dl() problem

Hello.. Is there a way of setting the extension_dir by not modifying php.ini ? i've tried with ini_set("extension_dir","/home/alexcos/www/phps"); dl("first_module.so"); Warning: Unable to load dynamic library '/usr/lib/php4/first_module.so' then , i've tried setting the extension_dir in a .htaccess file.. still , the same result.. i have developed a small module , but I can't use it.. my site is hosted on an service provider , and they don't allow me to copy the module to extension_dir or to change the php.ini.. what should I do ? Thanks Alex
