**Solved it**:

    apt-get install libzip-dev

will install the missing libzip-distribution



This might be helpful for webmin/virtualmin users running CentOS 7:

     yum install php-pecl-zip

This worked for me.

This worked for me with Amazon Linux:

    yum install libzip-devel.x86_64

At the time of this writing, I had to use libzip &gt; = 0.11.  The libzip/libzip-devel package on the official
CentOS x86_64 repository is still on 0.10.  To get around this, the Psychotic Ninja Plus x86_64 repository offers a 0.11 version.  Information for [libzip](https://centos.pkgs.org/7/psychotic-ninja-plus-x86_64/libzip-0.11.2-6.el7.psychotic.x86_64.rpm.html) and [libzip-devel](https://centos.pkgs.org/7/psychotic-ninja-plus-x86_64/libzip-devel-0.11.2-6.el7.psychotic.x86_64.rpm.html) on the Psychotic Ninja Plus repositories can be found on those links.

To install and use this version, you can run the following commands,

Download latest psychotic-release rpm from
`http://packages.psychotic.ninja/7/plus/x86_64/RPMS/`

Install psychotic-release rpm:
```bash
rpm -Uvh psychotic-release*rpm
```
Install libzip-devel rpm package:
```bash
yum --enablerepo=psychotic-plus install libzip-devel
```

Since it took me some time and research to figure this out i think it may come handy for mac-users:

You can install libzip through brew using:

    ruby -e &quot;$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)&quot; &lt; /dev/null 2&gt; /dev/null

And then:

    brew install libzip




I&#39;m trying to set up a simple systemd timer to run a bash script every day at midnight.

```systemctl --user status backup.service``` fails and logs the following:

    backup.service: Failed at step EXEC spawning /home/user/.scripts/backup.sh: No such file or directory.

    backup.service: Main process exited, code=exited, status=203/EXEC
    Failed to start backup.
    backup.service: Unit entered failed state.
    backup.service: Failed with result &#39;exit-code&#39;.

I&#39;m lost, since the files and directories exist. The script is executable and, just to check, I&#39;ve even set permissions to 777.

Some background:

The ```backup.timer``` and ```backup.service``` unit files are located in ```/home/user/.config/systemd/user```.

```backup.timer``` is loaded and active, and currently waiting for midnight.

Here&#39;s what it looks like:

    [Unit]
    Description=Runs backup at 0000

    [Timer]
    OnCalendar=daily
    Unit=backup.service

    [Install]
    WantedBy=multi-user.target

Here&#39;s ```backup.service```:

    [Unit]
    Description=backup

    [Service]
    Type=oneshot
    ExecStart=/home/user/.scripts/backup.sh

    [Install]
    WantedBy=multi-user.target

And lastly, this is a paraphrase of ```backup.sh```:
    
    #!/usr/env/bin bash

    rsync -a --delete --quiet /home/user/directory/ /mnt/drive/directory-backup/

The script runs fine if I execute it myself.

Not sure if it matters, but I use ```fish``` as my shell (started from .bashrc).

I&#39;m happy to post the full script if that&#39;s helpful.

We are running XAMPP with PHP 7.0 because our new products requires PHP 7.

But there are old projects which use functions like `mysql_connect`, etc. Those are removed in PHP 7.0.

So, is there a way to easily change PHP versions in XAMPP?


&gt; **Note**: Please don&#39;t suggest to upgrade old project to compatible with new versions because I am not in a position to do it because of that
&gt; decisions I can&#39;t get as a developer (just an employee).


Is there way to use two PHP versions in XAMPP?

I want to integrate Marketo form with my existing website on yii framework.
My code works on all the browsers except Firefox.

Excerpt from my code:

        $(&#39;#button&#39;).click(function () {
        var formData = {
            &#39;Email&#39;: $(&#39;#UserInfo_email&#39;).val(),
            &#39;FirstName&#39;: $(&#39;#UserInfo_first_name&#39;).val(),
            &#39;LastName&#39;: $(&#39;#UserInfo_last_name&#39;).val(),
            };
        MktoForms2.loadForm(&#39;//app-ab23.marketo.com&#39;, mcId, formId, function (form) {
            var myForm = MktoForms2.allForms()[0];
            myForm.addHiddenFields(formData);
            myForm.onSuccess(function (values, followUpUrl) {
                return false;
            });
            myForm.submit();
        });
    });

I get error on Firefox only with message 

&gt; Loading failed for the &amp;lt;script&amp;gt; with source “http://app-ab23.marketo.com/index.php/form/getForm?munchkinId=1111&amp;form=1111&amp;url=http%3A%2F%2Fblox.dev%2Fwizard%2Fmap&amp;callback=jQuery110207175825035737486_1503656391790&amp;_=1503656391791”.

other browsers do the job correctly

I need to integrate a new payment gateway to our corporate website, which is based on Social Engine. There is an extension for this `CMS` called Advanced Payment Gateways which allows integration of new gateways. In fact, it gets your gateway name and generates a skeleton structure zipped as a file so you can unzip and upload to your server and thus merge with the application directory. 

I&#39;m going to explain how I implement my gateway without Social Engine, and I hope someone can tell me how I can incorporate that into Social Engine.     

 1. First I connect to my `PSP` service: 

        $client = new nusoap_client(&#39;https://example.com/pgwchannel/services/pgw?wsdl&#39;);

 2. I prepare the following parameters in an array to send to `bpPayRequest`: 

    	$parameters = array(
    		&#39;terminalId&#39; =&gt; $terminalId,
    		&#39;userName&#39; =&gt; $userName,
    		&#39;userPassword&#39; =&gt; $userPassword,
    		&#39;orderId&#39; =&gt; $orderId,
    		&#39;amount&#39; =&gt; $amount,
    		&#39;localDate&#39; =&gt; $localDate,
    		&#39;localTime&#39; =&gt; $localTime,
    		&#39;additionalData&#39; =&gt; $additionalData,
    		&#39;callBackUrl&#39; =&gt; $callBackUrl,
    		&#39;payerId&#39; =&gt; $payerId);
    
    	// Call the SOAP method
    	$result = $client-&gt;call(&#39;bpPayRequest&#39;, $parameters, $namespace);

 3. If payment request is accepted, the result is a comma separated string, with the first element being **0**.   
Then we can send the second element (reference id) to payment
    gateway as follows via `POST` method:

    
        echo &quot;&lt;script language=&#39;javascript&#39; type=&#39;text/javascript&#39;&gt;postRefId(&#39;&quot; . $res[1] . &quot;&#39;);&lt;/script&gt;&quot;;
    
    	&lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot;&gt;    
    		function postRefId (refIdValue) {
    			var form = document.createElement(&quot;form&quot;);
    			form.setAttribute(&quot;method&quot;, &quot;POST&quot;);
    			form.setAttribute(&quot;action&quot;, &quot;https://example.com/pgwchannel/startpay&quot;);         
    			form.setAttribute(&quot;target&quot;, &quot;_self&quot;);
    			var hiddenField = document.createElement(&quot;input&quot;);              
    			hiddenField.setAttribute(&quot;name&quot;, &quot;RefId&quot;);
    			hiddenField.setAttribute(&quot;value&quot;, refIdValue);
    			form.appendChild(hiddenField);
    
    			document.body.appendChild(form);         
    			form.submit();
    			document.body.removeChild(form);
    		}
    		&lt;/script&gt;

 4. The gateway will return the following parameters via `POST` method to the call back `URL` that we provided in payment request:  
`RefId` (reference id as produced in previous steps)  
`ResCode` (Result of payment: 0 denotes success)  
`saleOrderId` (order id as passed during payment request)  
`SaleReferenceId` (sale reference code is given by PSP to the merchant)  

 5. If `ResCode` in the previous step was **0**, then we&#39;d need to pass the call `bpVerifyRequest` with the following parameters to verify payment, otherwise the payment will be canceled.    

         $parameters = array(
    		&#39;terminalId&#39; =&gt; $terminalId,
    		&#39;userName&#39; =&gt; $userName,
    		&#39;userPassword&#39; =&gt; $userPassword,
    		&#39;orderId&#39; =&gt; $orderId,
    		&#39;saleOrderId&#39; =&gt; $verifySaleOrderId,
    		&#39;saleReferenceId&#39; =&gt; $verifySaleReferenceId);
    
    	// Call the SOAP method
    	$result = $client-&gt;call(&#39;bpVerifyRequest&#39;, $parameters, $namespace);

 6. In case the result of `bpVerifyRequest` is zero, payment is certain and the merchant has to provide goods or services purchased. However, there is an optional method `bpSettleRequest`, which is used to request a settlement. It is called as follows:   
```
	$parameters = array(
		&#39;terminalId&#39; =&gt; $terminalId,
		&#39;userName&#39; =&gt; $userName,
		&#39;userPassword&#39; =&gt; $userPassword,
		&#39;orderId&#39; =&gt; $orderId,
		&#39;saleOrderId&#39; =&gt; $settleSaleOrderId,
		&#39;saleReferenceId&#39; =&gt; $settleSaleReferenceId);

	// Call the SOAP method
	$result = $client-&gt;call(&#39;bpSettleRequest&#39;, $parameters, $namespace);
```

I get confused by looking at default gateways in the Payment Gateways plugin e.g. PayPal, Stripe, 2Checkout, etc.  How am I incorporate this code logic into the newly created gateway skeleton? (the structure is shown below):

My register page is showing the form properly with CsrfToken (`{{ csrf_field() }}`) present in the form).

**Form HTML**

    &lt;form class=&quot;form-horizontal registration-form&quot; novalidate method=&quot;POST&quot; action=&quot;{{ route(&#39;register&#39;) }}&quot;&gt;
            {{ csrf_field() }}
            ....
    &lt;/form&gt;

I am using inbuilt authentication for the users. Have not changed anything except the routes and redirects.

When I submit the form (just after reloading also), it gives that **The page has expired due to inactivity. Please refresh and try again.** error.

My be I am missing a very small thing. But not sure what it is. Any help?

**Update**

Found the issue. The session driver was set to array. Changed it to file and the error is gone now.
But what is wrong if I use array?

&quot;The page has expired due to inactivity&quot; - Laravel 5.5

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.
