How find the Name in multidimensional arrays in php

Question

Is there a way to get the names of the form fields from $_POST ?

I know I can get the values with $_POST['foo'], but how do I get the list of names (not sure what they are called).

Any help is great.

It is called a *key*. – Devon Bessemer May 08 '15 at 01:09 — Devon Bessemer, May 08 '15 at 01:09

As simple as that

print_r($_POST);

print_r — Prints human-readable information about a variable

$_POST is an associative array. Use array_keys to get the keys of the array.

$names = array_keys($_POST);

An array consists of array key and value.

$array = array('color1' => 'red','color2' => 'blue', 'color3' => 'green');

to get the key values use

$keys = array_keys($array);
print_r($keys);
