Function list of php file

Question

How to get list of functions that are declared in a php file

Answer 1

Finding string (eg. Function names) in a file is simple with regex. Just read the file and parse the content using preg_match_all.

I wrote a simple function to get list of functions in a file.

$a = functions_in_file( "mylib.php" );
