get_defined_functions

get_defined_functions — Returns a multidimensional array containing a list of all defined functions, both built-in (internal) and user-defined. The internal functions will be accessible via $arr["internal"], and the user defined ones using $arr["user"]

Example:

function funct_four(){
    //do something
}

$arr = get_defined_functions();
var_dump($arr);

Always wondered why in one case such answer (nearly link to manual) will be downvoted -3 and worse and in other cases - upvoted to +5 and better, while it always should be just a comment I guess :p Will not upvote/dowvote anyway :p – Alma Do Aug 27 '13 at 10:14

@AlmaDoMundo A comment isn't an answer though :p He asked a very specific question and it had a very specific answer. In my opinion, posting it as a comment would have defeated the purpose of Stackoverflow. – Wayne Whitty Aug 27 '13 at 10:19
Link to manual is a specific answer? :p Not sure. Nevermind, just trying to clarify the criteria for myself (as I've seen many samples where such questions/answers were downvoted seriously instead) – Alma Do Aug 27 '13 at 10:21
Because this question have to be rather closed as a duplicate? – Your Common Sense Aug 27 '13 at 10:23

Try with get_defined_functions() like

$fun_arr = get_defined_functions();
print_r($fun_arr['user']);

print_r($fun_arr['user']); thank you.. :) – Manjunath Hegde Aug 27 '13 at 10:16
If so, then `print_r(get_defined_functions()['user'])` – Alma Do Aug 27 '13 at 10:19
