While statement in PHP

The While Statement
The while statement will execute a block of code if and as long as a condition is true.

Syntax:
while (condition)
code to be executed;

Example
The following example demonstrates a loop that will continue to run as long as the variable i is less than, or equal to 5. i will increase by 1 each time the loop runs:

<?php

            $i=1;

            while($i<=5)

            {

                        echo "The number is " . $i . "

                        $i++;

            }

?>
