php - http.so loaded but http_get undefined

Question

I have LAMP installed on my linux distribution:

///

PHP 5.4.9-4ubuntu2.4 (cli) (built: Dec 12 2013 04:29:20) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies with Xdebug v2.2.1, Copyright (c) 2002-2012, by Derick Rethans

///

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.

Now I am in the following scenario. Using the simple php code below:

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;

I got the following results:

///

boolean true

boolean true

boolean true

**boolean false**

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

"[Tue Dec 31 12:32:26 2013] [error] [client 127.0.0.1] PHP Fatal error: Call to undefined function http_get() in /home/user/main.php on line 32"

Could you please help me troubleshooting this?

(same issue using the console interactive mode php -a)

phpinfo() shows:

///

HTTP Support enabled Extension Version 2.0.3

As Michael Berkowski says, the 2.x branch is totally new and it works with a different API.

You can go with the 1.x branch and use the old functions this way:

pecl uninstal pecl_http
pecl install pecl_http-1.7.6

Then you can use http_get

Anyway, if this is a fresh new project, it is recommended to go with the newest API.
