1st) Consider using the .vimrc and ftplugin enhancements as per schlitt.info

2nd) Install phpm to use

a) on the command line phpm mysql_q OR b) install file attached to this page into your <install path="fooBar" /> as per your settings.xml (file by phpm)

Note: The attached file contains only methods with a parent class matching sf* as the file otherwise got too big for trac (some 680K). If you want a convenient way to access all methods in symfony, generate that file as following:

#install PHP Documentor and all of its dependencies
pear install --alldeps PHPDocumentor-beta

#install phpm, including the template files in /usr/share/php/data
phpdoc -o XML:phpm:default -ti symfony -t /home/me/tmp/doc/symfony-phpm -d /usr/share/php/symfony 

#that generates PHPDocumentor output that phpm uses, you can copy that file to the dir where all your phpm xml files reside (as set in settings.xml by editing <install path="fooBar" />)
