I’m using XAMPP for Windows and decided to try out Symfony 2.
As soon as I get to Symfony Configuration page it recommends me to install and enable intl.
I tried reading PEAR's and PECL's guides, since I’m total 0 on this topic(started learning PHP recently), but nothing worked.
I found php_intl.dll inside my C:\xamp\php\ext. The php.ini‘s extension_dir= is set to "C:\xampp\php\ext". I was only missing the extension=php_intl.dll inside php.ini, so I added it.
Unfortunately it didn’t work, and Symfony keeps asking me for intl.
