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.
