I recently spent several hours beating my head against the wall trying to figure out why Doctrine and Zend weren’t playing nice together. I was using the version of Apache and PHP that comes with Mac OS X Leopard. When trying to load up the site in my Zend framework I got the error:
Warning: Zend_Loader::include_once(Doctrine/Adapter/Mysql.php): failed to open stream: No such file or directory
Which made me think I was missing the mysql adapter for Doctrine. Looking in the Doctrine/Adapter folder, at least with the latest version, you’ll notice there is only a Mysqli.php no Mysql.php. This led me to think that I was missing some essential library for Doctrine. However, this was not the case. The issue is that the build of PHP that comes with Mac OS X Leopard does not include pdo_mysql. The extension is listed in the php.ini file and you can uncomment it, but it won’t load. Rather than try and compile PHP with pdo_mysql support I decided to move to MAMP. Which turned out to be a wonderful choice. It’s got pdo_mysql support in its PHP build. It’s also a great way to do local development since you can easily turn it on, or restart. I would highly recommend it for development on your local machine.
