symfony2 requirements cant be met

Question

Was trying to play with symfony2. If I hit the web/config.php of my symfony2 installation it shows me the following problems

Install and enable the mbstring extension.
Install and enable the intl extension (used for validators).
Install and enable a PHP accelerator like APC (highly recommended).
Install PDO drivers (mandatory for Doctrine).

I can understand that these are not mandatory ones but question is I fixed these in my php.ini file but still cant see any reflection in this page. Here is how I fixed the above problems

extension=php_intl.dll
extension=php_mbstring.dll
extension=php_pdo_mysql.dll

Didnt install anything for APC so no complain with that. Restarted apache server "thousand" times, but no luck.

Side Note:

I tried to figure out something from phpinfo() . I can see one discrepancy. The phpinfo is showing one of my old php directory path F:\\Softwares\\Development\\PHP\\php-5.5.13-x64 . This path used to exist in my system PATH variable earlier. But I myself remove this location from System PATH variable. But it is still visible in phpinfo(). But if I print the PATH variable from command prompt or cygwin console, it shows the correct PATH variable.

Also ran php app/check.php . It shows everything OK except the APC, which is completely fine for me. But it also shows that "PHP CLI can use a different php.ini file than the one used with your web server" .

Environment Details:

• OS: Windows 7
• php: php-5.4.30-Win32-VC9-x86
• Apache: Win32-2.4.9 VC9
• MySQL: mysql-5.6.19-winx64
• Not using any xampp/wampp etc.

Few more hear left on my head. Please help.

Make sure that you have these extensions in your ext directory, if not search and put it in the directory (for windows extension file type must be .dll).

• APC https://www.dropbox.com/s/hmnrgle8xing3fo/php_apc.dll
• INTL https://www.dropbox.com/s/wm14zk0grc6pm6v/php_intl.dll (you also need ICU lib)
• mbstring https://www.dropbox.com/s/wm14zk0grc6pm6v/php_intl.dll
• PDO mysql https://www.dropbox.com/s/hd5cm02oti8qw3s/php_pdo_mysql.dll

Also, don't forget to restart apache after changes in php.ini
