Is there a way to check if a function exists within a class?

Question

I\'m passing some post data to execute a function based on post data, to determine if this should execute I\'ve tried to use the following:

$SP = new StoredP         


        

Answer 1

method_exists checks for method of a class for a given object:

Docs Link: http://www.php.net/method_exists

if(method_exists($SP, $_POST['function'])) {
    {
        $SP->$_POST['function']();
    }
    else
    {
        echo 'function does not exist.';
    }

function_exists() and method_exists() are for these checks. First is for regular functions and second for OOP functions.
