How to run php extensions at runtime

Question

I'm trying to load a php extension at runtime. As the use of dl() is discouraged and it is removed from PHP i'm using php extension directives but it doesn't work either.

ini_set('extension','php_gmp.dll');

if(extension_loaded( 'gmp' ))
    echo 'GMP is Loaded';

Is it possible to do it ?

The reason why i want to do it is that my application needs gmp and want to load gmp even if gmp is not running on the web server.

Thanks

It is not possible to load extensions via ini_set. The extension directive is only changable in php.ini as described in the Path and Directories section.
