How To Get All the Keys Out of an Array? - PHP Script Tips - PHP Built-in Functions for Arrays
✍: FYIcenter.com
Function array_keys() returns a new array that contains all the keys of a given array. Here is a PHP script on how to use array_keys():
<?php $mixed = array(); $mixed["Zero"] = "PHP"; $mixed[1] = "Perl"; $mixed["Two"] = "Java"; $mixed["3"] = "C+"; $mixed[""] = "Basic"; $mixed[] = "Pascal"; $mixed[] = "FORTRAN"; $keys = array_keys($mixed); print("Keys of the input array:\n"); print_r($keys); ?>
This script will print:
Keys of the input array: Array ( [0] => Zero [1] => 1 [2] => Two [3] => 3 [4] => [5] => 4 [6] => 5 )
