How to find all PHP funtions/classes/constants

Hello everyone, I am in the process of updating the PHP syntax file for Vim, and I need to gather a list of all built-in PHP functions, constants, classes, interfaces, and preferably also the methods and class-constants from said built-in classes and interfaces. First I used my PHP's get_defined_functios() and similar classes to havest my list, but this misses out on any extensions I don't have compiled. Second, I tried to scan the PHP manual, but this is time consuming and not 100% accurate (page layout is very inconsistent). Does anyone know if it would be effective to 'grep' the PHP source code to find all these built-in words? regards, Peter Send instant messages to your online friends http://au.messenger.yahoo.com
