If you're experiencing this issue when you execute PHP command-line with wamp server, it's because PHP does not hold a reference to the wamp-modified <code>php.ini</code> file (only the apache instance does). Without it, things like <code>curl</code> will not work properly.

To fix this, you need to copy the <code>php.ini</code> file from the Apache folder to the PHP folder.

<ul>
<li>Apache Path: [wamp install dir]\bin\apache\apache2.2.22\bin\php.ini </li>
<li>PHP Path: [wamp install dir]\bin\php\php5.4.3\php.ini</li>
</ul>

You can update the apache/php versions in the folder-paths if yours don't match.

2 solutions:

<ol>
<li>Enable the plugin

<ul>
<li>in wamp this is done in the right click menu.</li>
<li>On Linux - it'll probably be in php.ini (though don't forget to restart Apache!)</li>
</ul></li>
<li>Check curl exists before attempting to use it:

<ul>
<li><code>if(!function_exists('curl_init')) echo "cURL not installed. Trying something else...";</code></li>
</ul></li>
</ol>

Uncomment this line in the php.ini

<pre><code>extension=php_curl.dll

And remember to set the extensions directory in your php.ini

<pre><code>extension_dir = “/usr/local/php5/ext”
</code></pre>

There is solution with all necessary details: 

<a href="http://www.youtube.com/watch?v=7qNTi1sEfE8" rel="nofollow">http://www.youtube.com/watch?v=7qNTi1sEfE8</a>

It is in French, but you can understand everything! I solved same problem, even don't speak French. :-)

Many answers forget to mention that you need to add new version of php_curl.dll file from this location: 
<a href="http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/" rel="nofollow">http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/</a>

I added new version of php_curl.dll from archive php_curl-5.4.3-VC9-x64.zip to folders:
C:\wamp\bin\php\php5.4.3\ext and C:\Windows\System32
and everything was fine!

I am having following error on using curlas extension

<blockquote>
 Fatal error: Call to undefined function curl_init() in C:\wamp\www***\index.php on line 15
</blockquote>

<hr>

I have following configuration 

<pre><code>;extension=php_bz2.dll 
extension=php_curl.dll 
;extension=php_dba.dll
</code></pre>

i installed 
 wampserver2.2e-php5.4.3-httpd2.2.22-mysql5.5.24-x64.exe

i tried to enable other extension also and restarted server but they local host is not able to load that extension.
