Nuemann "got to go to every php file and hunt for the ones that gets call up by init script somewhere"
@Nuemann Which is why you learn to use the tools of the trade. Happy to see you trying to figure things out but you are doing things the hard way if you dont use the tools we use (well atleast i use) :
FireFox web developer tools (inspector in secific)
WinMerge http://winmerge.org/
Programmers Notepad http://www.pnotepad.org/
OR
Notepad++ http://notepad-plus-plus.org/
And one of the tools i have used for a long time and it has been one of the most valuable tools i have used in a very long time
Agent Ransack http://www.mythicsoft.com/agentransack which will solve your problem in searching the files for what you want if you learn how to use it.
Good Luck :)
