while Loop

The while Loop

The while loop executes a block of code while a condition is true.

Syntax

while (condition)
  {
  code to be executed;
  }

Example

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

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

</body>
</html>
Output:
The number is 1
The number is 2
The number is 3
The number is 4
The number is 5
