title: http.so loaded but http_get undefined
body: <p>I have LAMP installed on my linux distribution:</p>
  
  <p>///</p>
  
  <p>PHP 5.4.9-4ubuntu2.4 (cli) (built: Dec 12 2013 04:29:20) 
  Copyright (c) 1997-2012 The PHP Group

  <p>///</p>
  
  <p>In order to use http_get from pecl_http php extension I have explicitly installed it and added the http.so extension to php.ini.</p>
  
  <p>Now I am in the following scenario. Using the simple php code below:</p>
  
  <pre><code>echo var_dump(extension_loaded("http"));
  
  echo var_dump(extension_loaded("raphf"));
  
  echo var_dump(extension_loaded("propro"));
  
  echo var_dump(function_exists("http_get"));
  
  $response = http_get("www.google.com");
  
  echo $response;
  </code></pre>
  
  <p>I got the following results:</p>
  
  <p>///</p>
  
  <pre><code>boolean true
  
  boolean true
  
  boolean true
  
  **boolean false**
  </code></pre>
  
  <p>I am not sure why extension_loaded("http") returns true but function_exists("http_get") returns false, so I cannot use the function http_get without getting the following in the Apache log file </p>

  <p>Could you please help me troubleshooting this?</p>
  
  <p>(same issue using the console interactive mode php -a)</p>
  
  <p>phpinfo() shows:</p>
