Zend Studio php_pdo_mysql.dll error

I started using phpunit, which is built into Zend Studio 7.2. Everything works fine until it encountered a database query that used PDO. The test case will timeout and zend studio will give you the error “Test case was unexpectedly terminated”. It took a lot of digging to find the real error in the windows event viewer:

Faulting application name: php-cgi.exe, version:, time stamp: 0x4abb41d8

The solution? While I had Zend Server installed and using PHP 5.3, Zend Studio’s internal version was using PHP 5.2.xxx. I’m pretty certain Doctrine, which uses PDO, requires PHP 5.3. I changed Zend Studio to PHP 5.3 and it worked. In Zend Studio, go to Window->preferences->php->debug and ensure the “PHP executable” is set to PHP 5.3. FYI – My “server” on this screen is set to “Local Zend Server”. Hope this helps!
