How to install phalcon on php
The installation always fails. Follow the instructions on the official website
First put it in the ext folder, then add extension=php_phalcon.dll in php.ini and then restart wamp and it will prompt this error...
Then I downloaded php5.dll and it prompted this error again
------Solution--------------------
My php is 5.4.20
php_phalcon.dll is version 5.4.12.0
No problem
print_r(preg_grep('/^phalcon/i', get_declared_classes()));
