I've got some similar php files that I need to analyze to find the differences..I've done some searching, but haven't been able to quite find what I'm looking for.
I know it exists, but does anyone know of some software off the top of their head that can take 2 almost identical php files and show the differences between the two?
There are quite a lot of tools that can compare files; some more specific than others. Though a popular open source tool for comparing files on Windows is WinMerge: http://winmerge.org/
Possibly the best-known tool in this category is Beyond Compare. See http://www.scootersoftware.com (But I don't have any personal experience of it.)
I personally like both WinMerge and BeyondCompare. I've used both, never really had issues with either of them. I've also used KDiff on linux, diff (the command line) on linux, and a few lesser knowns that I can't quite remember the names of.
So pick either one, try them both, and then go with the one you like best. But I'll at least say, both were acceptable in my usage of them (and continued usage of them).
