Unterminated entity reference in PHP

I&#39;m running windows 10 fresh copy and I just installed visual studio code.
I was trying to develop a PHP project using VS Code.
But I&#39;m having trouble in setting up the environment.

I saw a blog post and I downloaded the binary file of PHP 7 and place it in the &quot;C&quot; drive. Then I set path variable too.

But still, I&#39;m getting this issue.

PHP executable not found. Install PHP 7 and add it to your PATH or set the php.executablePath setting

Does PHP 7 support strict typing for resources? If so, how?

For example:


    	declare (strict_types=1);
    
    	$ch = curl_init ();
    	test ($ch);
    
    	function test (resource $ch)
    	{

    	}

The above will give the error: 

&gt; Fatal error: Uncaught TypeError: Argument 1 passed to test() must be an instance of resource, resource given

A var_dump on `$ch` reveals it to be **resource(4, curl)**, and the manual says `curl_init ()` returns a resource.

Is it at all possible to strictly type the `test()` function to support the `$ch variable`?

PHP 7 and strict &quot;resource&quot; types

I was testing return types with PHP 7.
 
I&#39;ve created a simple script to test return types of PHP 7:

    &lt;?php
    
    Class Obj {
        
        public function __construct(){
            
        }
        
        public function test(): string { //a string needs to be returned
            return &quot;ok&quot;;
        }
        
    }
    
    function foo(): Obj { //instance of Obj needs to be returned
        return new Obj();
    }
    
    $o = foo();
    echo $o-&gt;test(); // output: ok

Now in other programming languages when you specify a return type `void` it means you cannot return anything or you will get an error. So I wrote this script:

    &lt;?php

        function foo(): void {
    
        }
    
        foo(); 

Now in above script the expected output is nothing. 
Instead it gives me a Fatal error:

&gt;Fatal error: Return value of foo() must be an instance of void, none returned on line 2

My question is (I couldn&#39;t find it), in PHP 7 will there be a similar `void` type?

Void as return type

Is there a ternary operator or the like in PHP that acts like `??` of C#?

`??` in C# is clean and shorter, but in PHP you have to do something like:

    // This is absolutely okay except that $_REQUEST[&#39;test&#39;] is kind of redundant.
    echo isset($_REQUEST[&#39;test&#39;])? $_REQUEST[&#39;test&#39;] : &#39;hi&#39;;

    // This is perfect! Shorter and cleaner, but only in this situation.
    echo null? : &#39;replacement if empty&#39;;

    // This line gives error when $_REQUEST[&#39;test&#39;] is NOT set.
    echo $_REQUEST[&#39;test&#39;]?: &#39;hi&#39;;

Hi, can someone tell me what colon is doing here, in this method declaration inside PHP interface? Is this PHP 7 syntax and what array is meaning here? Method must return array or something else?

I have installed both php5.6 and php7.0 from PPA on Ubuntu according to this manual

[http://lornajane.net/posts/2016/php-7-0-and-5-6-on-ubuntu][1]

But I didn&#39;t get how to install extensions using `pecl` for php5.6 or php7.0.

For example I have already installed version of `libevent` or `amqp` in php5.6.

Now when I type `pecl install libevent` and my active php version is php7.0 (using `update-alternatives --set php /usr/bin/php7.0), `pecl` returns message that `libevent` already installed.

But it was installed only for php5.6 (when this version was active) and now I want to do it for php7.0.

Which commands could help me?

**UPD**

I have found this commands for switch pecl to php7.0 and packet them to executable bash scripts:

    #!/bin/bash

    sudo update-alternatives --set php /usr/bin/php7.0
    
    sudo pecl config-set php_ini /etc/php/7.0/cli/php.ini
    sudo pecl config-set ext_dir /usr/lib/php/20151012/
    sudo pecl config-set bin_dir /usr/bin/
    sudo pecl config-set php_bin /usr/bin/php7.0
    sudo pecl config-set php_suffix 7.0

and for php5.6

    #!/bin/bash

    sudo update-alternatives --set php /usr/bin/php5.6
    
    sudo pecl config-set php_ini /etc/php/5.6/cli/php.ini
    sudo pecl config-set ext_dir /usr/lib/php/20131226/
    sudo pecl config-set bin_dir /usr/bin/
    sudo pecl config-set php_bin /usr/bin/php5.6
    sudo pecl config-set php_suffix 5.6

But they are not help, pecl still gives me `list` of already installed extensions to php5.6, even if I switched to php7.

    pecl list
    Installed packages, channel pecl.php.net:
    =========================================
    Package  Version State
    amqp     1.7.1   stable
    libevent 0.1.0   beta
    stats    1.0.3   stable

It should be empty for php7.0 !

How to solve the problem?

**UPD**

For amqp I have just installed php-amqp package without using pecl.

    apt-get install php-amqp

And libevent still not exists for php7.
But I hadn&#39;t found a way to switch pecl installation between 5.6 and 7 version, so question is still open.

PHP7 : install ext-dom issue

I&#39;ve installed PHP 7 using [this repo][1], but when I try to run ``composer install``, it&#39;s giving this error:

&gt; - [package] requires ext-curl * -&gt; the requested PHP extension curl is missing from your system.

With PHP 5, you can easily install it by running the ``yum`` or ``apt-get install php5-curl`` command, but I can&#39;t find how to install the PHP 7 equivalent.

PHP 7, which will come out in November this year will introduce the Spaceship (&lt;=&gt;) operator. What is it and how does it work?

&lt;sub&gt;This question already has [an answer][1] in our general reference question about PHP operators.&lt;/sub&gt;


  [1]: https://stackoverflow.com/questions/3737139/reference-what-does-this-symbol-mean-in-php/31298778#31298778

What is &lt;=&gt; (the &#39;Spaceship&#39; Operator) in PHP 7?

PHP 7 introduces [return type declarations][1]. Which means I can now indicate the return value is a certain class, interface, array, callable or one of the newly hintable scalar types, as is possible for function parameters.

    function returnHello(): string {
    	return &#39;hello&#39;;
    }

Often it happens that a value is not always present, and that you might return either something of some type, or null. While you can make parameters nullable by setting their default to null (`DateTime $time = null`), there does not appear to be a way to do this for return types. Is that indeed the case, or am I somehow not finding how to do it? These do not work:

    function returnHello(): string? {
    	return &#39;hello&#39;;
    }

    function returnHello(): string|null {
    	return &#39;hello&#39;;
    }

The mcrypt-extension is [deprecated][1] will be removed in PHP 7.2 according to the comment posted [here][2]. So I am looking for an alternative way to encrypt passwords.

Right now I am using something like

    mcrypt_encrypt(MCRYPT_RIJNDAEL_128, md5($key, true), $string, MCRYPT_MODE_CBC, $iv)

I need your opinion for the best/strongest way to encrypt passwords, the encrypted password should of course supported by PHP 7.xx and should also be decryptable because my customers do want to have an option to &#39;recover&#39; their passwords without generating a new one.

I have updated my class definitions to make use of the newly introduced property type hints, like this:

```php
class Foo {
    
    private int $id;
    private ?string $val;
    private DateTimeInterface $createdAt;
    private ?DateTimeInterface $updatedAt;
    
    public function __construct(int $id) {
        $this-&gt;id = $id;
    }


    public function getId(): int { return $this-&gt;id; }
    public function getVal(): ?string { return $this-&gt;val; }
    public function getCreatedAt(): ?DateTimeInterface { return $this-&gt;createdAt; }
    public function getUpdatedAt(): ?DateTimeInterface { return $this-&gt;updatedAt; }
    
    public function setVal(?string $val) { $this-&gt;val = $val; }
    public function setCreatedAt(DateTimeInterface $date) { $this-&gt;createdAt = $date; }
    public function setUpdatedAt(DateTimeInterface $date) { $this-&gt;updatedAt = $date; }
}
```

But when trying to save my entity on Doctrine I am getting an error saying:

&gt; Typed property must not be accessed before initialization 

This not only happens with `$id` or `$createdAt`, but also happen with `$value` or `$updatedAt`, which are nullable properties.

Why I am suddenly getting a &quot;Typed property must not be accessed before initialization&quot; error when introducing properties type hints?

Does php 7 support type hinting for class properties? 

I mean, not just for *setters/getters* but for the property itself. 

Something like:

    class Foo {
        /**
         *
         * @var Bar
         */
        public $bar : Bar;
    }
    
    $fooInstance = new Foo();
    $fooInstance-&gt;bar = new NotBar(); //Error

Type hinting for properties in PHP 7?

**UPDATE**: PHP 7.4 now [does support covariance and contravariance][1] which addresses the major issue raised in this question.  

----------

I have run into something of an issue with using return type hinting in PHP 7.  My understanding is that hinting `: self` means that you intend for an implementing class to return itself.  Therefore I used `: self` in my interfaces to indicate that, but when I tried to actually implement the interface I got compatibility errors.  

The following is a simple demonstration of the issue I&#39;ve run into: 

    interface iFoo
    {
    	public function bar (string $baz) : self;
    }
    
    class Foo implements iFoo
    {
    	
    	public function bar (string $baz) : self
    	{
    		echo $baz . PHP_EOL;
    		return $this;
    	}
    }
    
    (new Foo ()) -&gt; bar (&quot;Fred&quot;) 
    	-&gt; bar (&quot;Wilma&quot;) 
    	-&gt; bar (&quot;Barney&quot;) 
    	-&gt; bar (&quot;Betty&quot;);

The expected output was: 

&gt; Fred
&gt; Wilma
&gt; Barney
&gt; Betty

What I actually get is: 

&gt; PHP Fatal error:  Declaration of Foo::bar(int $baz): Foo must be compatible with iFoo::bar(int $baz): iFoo in test.php on line 7

The thing is Foo is an implementation of iFoo, so as far as I can tell the implementation should be perfectly compatible with the given interface.  I could presumably fix this issue by changing either the interface or the implementing class (or both) to return hint the interface by name instead of using `self`, but my understanding is that semantically `self` means &quot;return the instance of the class you just called the method on&quot;.  Therefore changing it to the interface would mean in theory that I could return any instance of something that implements the interface when my intent is for the invoked instance is what will be returned.  

Is this an oversight in PHP or is this a deliberate design decision?  If it&#39;s the former is there any chance of seeing it fixed in PHP 7.1?  If not then what is the correct way of return hinting that your interface expects you to return the instance you just called the method on for chaining?

PHP 7 interfaces, return type hinting and self

Maybe I missed something but is there any option to define that function should have argument or return for example array of User objects?

Consider the following code:

    &lt;?php
    
    class User
    {
        protected $name;
    
        protected $age;
    
        /**
         * User constructor.
         *
         * @param $name
         */
        public function __construct(string $name, int $age)
        {
            $this-&gt;name = $name;
            $this-&gt;age = $age;
        }
    
        /**
         * @return mixed
         */
        public function getName() : string
        {
            return $this-&gt;name;
        }
    
        public function getAge() : int
        {
            return $this-&gt;age;
        }
    }
    
    function findUserByAge(int $age, array $users) : array
    {
        $result = [];
        foreach ($users as $user) {
            if ($user-&gt;getAge() == $age) {
                if ($user-&gt;getName() == &#39;John&#39;) {
                    // complicated code here
                    $result[] = $user-&gt;getName(); // bug
                } else {
                    $result[] = $user;
                }
            }
        }
    
        return $result;
    }
    
    $users = [
        new User(&#39;John&#39;, 15),
        new User(&#39;Daniel&#39;, 25),
        new User(&#39;Michael&#39;, 15),
    ];
    
    $matches = findUserByAge(15, $users);
    
    foreach ($matches as $user) {
        echo $user-&gt;getName() . &#39; &#39;.$user-&gt;getAge() . &quot;\n&quot;;
    }

Is there any option in PHP7 to tell function `findUserByAge` should return array of users? I would expect that when type hinting was added it should be possible but I haven&#39;t found any info for type hinting for array of objects so probably it&#39;s not included in PHP 7. If it&#39;s not included, do you have Any clue why it was not included when type hinting was added?

    pecl install zip

yields the error 

&gt; configure: error: Please reinstall the libzip distribution

I did not find anything related to this error.

I tried `apt-get install libzip` but the package was not found.

I am not able to see the MySQLi extension using phpinfo() either. How can I enable/install MySQLi extension in PHP&amp;nbsp;7?

That&#39;s why I cannot use phpMyAdmin. It says &quot;The mysqli extension is missing.&quot;





How can I enable the MySQLi extension in PHP 7?

I&#39;m testing PHP7, and have a weird issue after a recent update. SimpleXML should be enabled by default, and my `phpinfo` page shows that it is available:

[![enter image description here][1]][1]

However, the functions are not available:

    &lt;?php

    if (function_exists(&#39;simplexml_load_file&#39;)) {
        echo &quot;simpleXML functions are available.&lt;br /&gt;\n&quot;;
    } else {
        echo &quot;simpleXML functions are not available.&lt;br /&gt;\n&quot;;
    }

    // result-- NOT available

And the module isn&#39;t listed as loaded:

    ~ $ php -m
    [PHP Modules]
    calendar
    Core
    ctype
    curl
    ...
    Reflection
    session
    shmop
    sockets
    SPL
    standard
    sysvmsg
    sysvsem
    sysvshm
    tokenizer
    Zend OPcache
    zlib


Anyone know if there&#39;s a workaround for this?

PHP 7 simpleXML

I have some methods that can return **one of two return types**. I&#39;m using a framework utilizing MCV so refactoring these few functions in particular is not appealing.

Is it possible to declare the return type returning one or the other and failing on anything else?


    function test(): ?
    {
        if ($this-&gt;condition === false) {
            return FailObject;
        }

        return SucceedObject;
    }

Is it possible to specify multiple return types on PHP 7?

I am very happy with the new features in PHP 7. But I am confused on how to return an array of objects in PHP 7.

For example, we have a class `Item`, and we want to return an array of objects of this class from our function:

    function getItems() : Item[] {
    }

But it does not work this way.

After upgrade to PHP 7 the logs almost choked on this kind of errors:

`PHP Warning: Declaration of Example::do($a, $b, $c) should be compatible with ParentOfExample::do($c = null) in Example.php on line 22548`

How do I silence these and only these errors in PHP 7?

- Before PHP 7 they were `E_STRICT` type of warnings [which could be easily dealt with](https://stackoverflow.com/questions/1248952/php-5-disable-strict-standards-error). Now they&#39;re just plain old warnings. Since I **do** want to know about other warnings, I can&#39;t just turn off all warnings altogether.

- I don&#39;t have a mental capacity to rewrite these legacy APIs not even mentioning all the software that uses them. Guess what, nobody&#39;s going to pay for that too. Neither I develop them in the first place so I&#39;m not the one for blame. (Unit tests? Not in the fashion ten years ago.) 

- I would like to avoid [any trickery][1] with `func_get_args` and similar as much as possible.

- Not really I want to downgrade to PHP 5.

- I still want to know about other errors and warnings.

Is there a clean and nice way to accomplish this?

Silence &quot;Declaration ... should be compatible&quot; warnings in PHP 7

I have **Ubuntu 16.04 LTS** running with **PHP7** and phpmyadmin installed.
However, I get a lot of deprecation notices like:

    Deprecation Notice in ./../php/php-gettext/streams.php#48  
    Methods with the same name as their class will not be constructors in a future version of PHP; StringReader has a deprecated constructor
     
    Backtrace  
    ./../php/php-gettext/gettext.inc#41: require()  
    ./libraries/select_lang.lib.php#477: require_once(./../php/php-gettext/gettext.inc)  
    ./libraries/common.inc.php#569: require(./libraries/select_lang.lib.php)  
    ./index.php#12: require_once(./libraries/common.inc.php)

Is this a problem? How can I get rid of these notices (they pop up each time a page is loaded or action is performed)?

PHP 7 with phpmyadmin gives lots of Deprecation Notices

I am trying to setup webserver with `PHP 7 RC3` + `Nginx` on `Ubuntu 14.04` (for test purposes).

I installed Ubuntu in Vagrant using `ubuntu/trusty64` and PHP 7 RC 3 from Ondřej Sur&#253; (https://launchpad.net/~ondrej/+archive/ubuntu/php-7.0).

I can not find the way to install `MySQL PDO` (PHP sees `PDO` class but not anything related to MySQL, like `PDO::MYSQL_ATTR_DIRECT_QUERY` etc.)

Looks like there is no lib `php7.0-mysql` (by analogy with standard `php5-mysqlnd` and `php7.0-fpm` etc. from Ondřej)

Section `PDO` in `phpinfo()`:

    PDO support	     enabled
    PDO drivers	     no value

How can I get it?

Recently the new php7 has been released. However, when I am trying to install the gd package, the library can not be found.

I have tried through

    sudo apt-get install php70-gd 
and

    sudo apt-get install php70-php-gd

Does anybody have an idea if gd is available for php 7?

After I upgraded **php5** to **php7**, I get an error 500 with

&gt; PHP Fatal error:  Uncaught Error: Call to undefined function mysql_connect()

I put this into my apt sources in order to get php7 right now:

&gt; deb http://packages.dotdeb.org jessie all&lt;br /&gt;
&gt; deb-src http://packages.dotdeb.org jessie all

What I basically did is:

    apt-get remove php5
    apt-get install php7-*

*I&#39;m using the current version of Debian Jessie.*

But I still get this. There are a lot of questions here on SO and I definitely checked them all out. But I didn&#39;t find an answer there yet.

&quot;Call to undefined function mysql_connect()&quot; after upgrade to php-7

I&#39;m currently migrating my website from PHP5 to PHP7, and I&#39;ve started using the strict typing feature that was added. However this requires me to begin all files with the following line:

    &lt;?php declare(strict_types=1);
    
    // All other code here
    // ...

So I was wondering, is there any way to enable `strict_types` globally using something like `php.ini` or the apache configuration file so I don&#39;t have to write this line every time, and if so how could I enable this?
