At least some IDE‘s have a means of searching through your current project for all instances of certain variables, function calls, etc. If you are using an IDE, check its help.

If you are using a *nix system, you can use grep to search:

grep do_something *.php'

The above will search your current working directory for the text ‘do_something’ in all files ending with the ‘.php’ extension. You can expand this to search all subdirectories of the current directory using the find command:

find . -name "*.php" -exec grep do_something {} \;

Use ‘man grep’ and ‘man find’ from your *nix command line to learn more.

If you are on Windows, I believe the find command can do similar things, I am not as familiar with it, but the basic syntax should look something like:

find "do_something" *.php
