How can i enable php extension with .htaccess file

Question

I need to enable php_intl extension only in a subdomain of my website, so i use the .htaccess file to do it with this code.

<IfModule mod_php4.c>
    php_extension_dir php_intl.dll
    php_extension php_intl.dll
</IfModule>

But not work. Someone helpe me, please?

Answer 1

The directive php_extension_dir should be:

php_extension_dir <path_to__php_extensions>

Where <path_to_php_extensions> is the absolute path to where your PHP extensions are installed. Simply putting the file name here does nothing, since a path value is expected.

If this still does not work, then PHP is set up as CGI and therefore cannot use htaccess to load modules. Take a look here if that is the case.
