php cannot load pecl http extension

Question

I have installed pecl_http on a PLESK server (which seems to be successful) but for some reason, the http extension will not load into PHP.

var_dump(extension_loaded("http"));

gives me bool(false).

pecl info pecl_http gives me a lot of info and if I run php -me http is also listed.

php -i | grep "http_request" gives me:

http_request => N/A => 0 => 0
http_request_datashare => GLOBAL => 1 => 0
http_request_pool => N/A  => 0 => 0

and if I run pecl run-tests -p pecl_http I get a lot of FAILs

and I am also getting

Fatal error: Call to undefined function http_get()

http.so is located inside /usr/lib/php/modules/ which is also defined as the extension dir in php.ini - all other extensions loads fine.

What have I missed?

Which Plesk, OS and PHP version have you installed on your server? — Oleg Neumyvakin

OS is Linux 2.6.32-042stab072.10, PLESK is 10.4.4 Update #47 and PHP is 5.3.21 — Morten Hagh

I have build pecl_http and add extension=http.so in /etc/php.d/http.ini. And it looks like everything fine php -r 'var_dump(extension_loaded("http"));' returns bool(true). Does this file exists on your server ls -la /usr/lib64/php/modules/http.so -rwxr-xr-x 1 root root 1642342 Mar 1 08:39 /usr/lib64/php/modules/http.so ? (lib64 - because i have Centos 5.9 x64 ) — Oleg Neumyvakin

I have this exact problem on CentOS, followed all the instructions above and php -r "dl('http.so');" returns this PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/http.so' - /usr/lib64/php/modules/http.so: undefined symbol: php_json_decode in Unknow n on line 0 Also, php -me does not have http included.

Your issue is not related to this question. Is php-json package is installed on server?(rpm -qa | grep -e php.*json)
