I have not been able to get the php_ibm_db2.dll extension to work correctly under WAMP 2.0. It works using CLI but won't work through Apache.
I receive the following error:
PHP Startup: Unable to load dynamic library 'E:/wamp/bin/php/php5.2.5/ext/php_ibm_db2.dll' - The specified module could not be found. in Unknown on line 0
I am currently using PHPEd 5.8 and set up the internal Apache server the exact same way and it worked immediately.
