If you&#39;re on Windows:

Go to your php.ini file and remove the `;` mark from the beginning of the following line:

    ;extension=php_curl.dll

After you have saved the file you *must* restart your HTTP server software (e.g. Apache) before this can take effect.

----------


For Ubuntu 13.0 and above, simply use the debundled package. In a terminal type the following to install it and do not forgot to restart server.

    sudo apt-get install php-curl

Or if you&#39;re using the old PHP5

    sudo apt-get install php5-curl

or

    sudo apt-get install php5.6-curl

Then restart apache to activate the package with

    sudo service apache2 restart

The CURL extension `ext/curl` is not installed or enabled in your PHP installation. Check the [manual][1] for information on how to install or enable CURL on your system.

An _implicit_ question to newcomers to Scala seems to be: where does the compiler look for implicits? I mean implicit because the question never seems to get fully formed, as if there weren&#39;t words for it. :-) For example, where do the values for `integral` below come from?

    scala&gt; import scala.math._
    import scala.math._
    
    scala&gt; def foo[T](t: T)(implicit integral: Integral[T]) {println(integral)}
    foo: [T](t: T)(implicit integral: scala.math.Integral[T])Unit
    
    scala&gt; foo(0)
    scala.math.Numeric$IntIsIntegral$@3dbea611
    
    scala&gt; foo(0L)
    scala.math.Numeric$LongIsIntegral$@48c610af

Another question that does follow up to those who decide to learn the answer to the first question is how does the compiler choose which implicit to use, in certain situations of apparent ambiguity (but that compile anyway)?

For instance, `scala.Predef` defines two conversions from `String`: one to `WrappedString` and another to `StringOps`. Both classes, however, share a lot of methods, so why doesn&#39;t Scala complain about ambiguity when, say, calling `map`?

**Note:** this question was inspired by [this other question][1], in the hopes of stating the problem in a more general manner. The example was copied from there, because it is referred to in the answer.

Is there a way to convert a string to binary then back again in the standard PHP library?

To clarify what I&#39;m trying to do is store a password on a database. I&#39;m going to convert it first using a hash function then eventually store it as binary.

---

I&#39;ve found the best way is to use this function. Seems to hash and output in binary at the same time.

As we know, creating anonymous objects in JavaScript is easy, like the code below:

    var object = { 
        p : &quot;value&quot;, 
        p1 : [ &quot;john&quot;, &quot;johnny&quot; ]
    };

    alert(object.p1[1]);

Output:

    an alert is raised with value &quot;johnny&quot;

Can this same technique be applied in PHP? Can we create anonymous objects in PHP?

Current situation: I have dependencies in my project that I solve by using dependency injection. I want to take the next logic step by using a dependency injection container (DIC) to ease the management of my dependencies and to lazy-load classes.

I looked at [Bucket](https://github.com/troelskn/bucket), [Pimple](http://pimple.sensiolabs.org/), and [sfServiceContainer](http://components.symfony-project.org/dependency-injection/), ran some test and really appreciate how DIC’s work. I’d probably go for Pimple because of its simplicity and raw power. If I didn’t have this problem:

Due to the abstraction that DIC’s offer, the IDE I’m using (PHPStorm) no longer understands what’s going on in my code. It doesn’t understand that $container[&#39;mailer&#39;] or $sc-&gt;mailer is holding a class object. I also tried Netbeans IDE: same problem.

This is really a problem for me because my IDE becomes useless. I don’t want to program without code hints, autocompletion and refactoring tools when dealing with classes. And I don’t want my IDE to find all kinds of false positives when validating code.

So my question is: Has anyone dealt with this problem and found a solution?

How do I make my PHP IDE understand Dependency Injection Containers?

I have an array like:

    $array = array(&#39;foo&#39; =&gt; &#39;bar&#39;, 33 =&gt; &#39;bin&#39;, &#39;lorem&#39; =&gt; &#39;ipsum&#39;);
    echo native_function($array, 0); // bar
    echo native_function($array, 1); // bin
    echo native_function($array, 2); // ipsum

So, this native function would return a value based on a numeric index (second arg), ignoring assoc keys, looking for the real position in array.

Are there any native function to do that in PHP or should I write it?
Thanks

Is it possible to use Sockets.io on the client side and communicate with a PHP based application on the server? Does PHP even support such a &#39;long-lived connection&#39; way of writing code? 

All the sample code I find for socket.io seems to be for node.js on the server side, so no help there.

I am using [XAMPP](http://www.apachefriends.org) for development. Recently I upgraded my installation of xampp from an old version to 1.7.3. 

Now when I curl HTTPS enabled sites I get the following exception

&gt; Fatal error: Uncaught exception &#39;RequestCore_Exception&#39; with message
&gt; &#39;cURL resource: Resource
&gt;     id #55; cURL error: SSL certificate problem, verify that the CA cert is OK. Details:
&gt;     error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed (60)&#39;

Everyone suggest using some specific curl options from PHP code to fix this problem. I think this shouldn&#39;t be the way. Because I didn&#39;t have any problem with my old version of XAMPP and happened only after installing the new version. 

I need help to figure out what settings change in my PHP installation, Apache etc can fix this problem.

I need to make a POST request via cURL from the command line. Data for this request is located in a file. I know that via PUT this could be done with the `--upload-file` option.

I need to download remote file using curl.

Here&#39;s the sample code I have:

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    
    $st = curl_exec($ch);
    $fd = fopen($tmp_name, &#39;w&#39;);
    fwrite($fd, $st);
    fclose($fd);
    
    curl_close($ch);

But it can&#39;t handle big files, because it reads to memory first.

Is it possible to stream the file directly to disk?
