I always liked the qw function from perl. You could easily make an array just by seperating the values with whitespaces. For example:

1
2

#!usr/bin/perl 
$array = qw("first second third fourth");

You would now have an array consisting of the values ‘first’, ’second’, ‘third’ and ‘fourth’. in PHP you would have to type the following code.

1
2
3

<?php
$array = array('first', 'second', 'third', 'fourth'); 
?>

This is much longer than the perl function.. So I simply made the qw function for PHP. It was actually very simple.

1
2
3
4
5
6
7

<?php 
function qw($string)
{
	$array = explode(' ', $string);
	return $array;
}
?>

Sample use:

1
2
3
4

<?php
$array = qw('first second third fourth fifth');
print_r($array);
?>

Output:

Array
(
    [0] => first
    [1] => second
    [2] => third
    [3] => fourth
    [4] => fifth
)
