Function list of php file

Question

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

Answer 1

I solved this problem with array_diff

$funcs = get_defined_functions()["user"];

require_once 'myFileWithNewFunctions.php'; // define function testFunc() {} here

var_dump( array_values( array_diff(get_defined_functions()["user"], $funcs) ) )
// output: array[ 0 => "test_func"]

Update

To get the "real" functions name try this

foreach($funcsDiff AS $newFunc) {
   $func = new \ReflectionFunction($newFunc);
   echo $func->getName(); // testFunc
}
