do-while Loop in PHP

  • 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.
  • The do-while would execute its statements at least once, even if the condition fails for the first time itself.

Syntax

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

Example

The following example show the do-while loop that starts with a=1. It will then increment a with 1, and write some output. Then the condition is checked, and the loop will continue to run as long as a is less than, or equal to 5:

<html>

<body>

    <?php

    $a=1;

    do

    {

    $a++;

    echo "The number is " . $a . "<br />";

    }

    while ($a<=5);

    ?>

</body>

</html>
