This tutorial will show you how to use PHP while operator

while loops are the simplest type of loop in PHP. They behave just like their C counterparts.

Next example will show you simple code for printing the digits from 10 to 1.

<?php
$k=10;
while($k!=0) {
    echo "$k\n";
    $k--;
}
?>
The result from above PHP script will be:

10
9
8
7
6
5
4
3
2
1
Also while can be used for listing arrays:

<?php
$array=array("One", "Two", 3, "Apple");
while(list($key,$value)=each($array)) {
    echo "$key : $value\n";
}
?>
The result from above PHP script will be:

0 : One
1 : Two
2 : 3
3 : Apple
