PHP while Loop

The while loop executes a block of code as long as the specified condition is true.

Syntax

while (condition is true) {
code to be executed;
}

The example below first sets a variable $x to 1 ($x = 1). Then, the while loop will continue to run as long as $x is less than, or equal to 5 ($x <= 5). $x will increase by 1 each time the loop runs ($x++):

Example

<?php
$x = 1;

while($x <= 5) {
echo "The number is: $x <br>";
$x++;
}
?>
