PHP while Loop

In this tutorial, you will learn about PHP while Loop step by step. So without much to do, let’s get started.

The while loop – Loops through a block of code as long as the specified situation is true.

The PHP whilst 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;

}

Examples

The example below displays the numbers from 1 to 5:

Example

<!DOCTYPE html>
<html>
<body>

<?php  
$x = 1;
 
while($x <= 5) {
  echo "The number is: $x <br>";
  $x++;
} 
?>  

</body>
</html>

Example Explained

• $x = 1; – Initialize the loop counter ($x), and set the start value to 1

• $x <= five – Continue the loop so long as $x is less than or equal to 5

• $x++; – Increase the loop counter value by 1 for each iteration

This example counts to 100 by tens:

Example

<!DOCTYPE html>
<html>
<body>

<?php  
$x = 0;
 
while($x <= 100) {
  echo "The number is: $x <br>";
  $x+=10;
}
?>  

</body>
</html>

Example Explained

• $x = 0; – Initialize the loop counter ($x), and set the begin cost to 0

• $x <= 100 – Continue the loop as long as $x is less than or equal to 100

• $x+=10; – Increase the loop counter value by way of 10 for each iteration
