do...while Statement

The do...while Statement

The do...while statement will always execute the block of code once, it will then check the condition, and repeat the loop while the condition is true.

Syntax

do
  {
  code to be executed;
 
}
while (condition);

Example

The example below first sets a variable i to 1 ($i=1;).
Then, it starts the do...while loop. The loop will increment the variable i with 1, and then write some output. Then the condition is checked (is i less than, or equal to 5), and the loop will continue to run as long as i is less than, or equal to 5:
<html>
<body>

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

</body>
</html> 
Output:
The number is 2
The number is 3
The number is 4
The number is 5
The number is 6
