Matching a function name

I need a regex that matches all instances of a particular PHP function name in given a piece of code.

The regex should match foo in:

foo("qwe");
function foo($param);
return foo();

An not match foo in:

my_foo("qwe");
foo_bar();
"some foo string"

Try \bfoo\([^\)]*\). This will match "some foo() string" but not "some foo string" though. Don't know if that's good enough for you.

You will want this:

/\bfoo\b/

The \b checks for word boundary. Basically the start or end of a word (which why it's on both sides).
