The do...while statement will execute a block of code at least once - it then will repeat the loop as long as a condition is true.

It executes the code at least one time always because the condition is checked after executing the code.


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

In a do...while loop the condition is tested AFTER executing the statements within the loop.

Let's put these syntax into real use.


<?php 
$x = 10; 
do {
 echo "Number = $x <br>";
 $x++;
} while ($x <= 20);
?>

This will produce the following result −


 Number = 10
 Number = 11
 Number = 12
 Number = 13
 Number = 14
 Number = 15
 Number = 16
 Number = 17
 Number = 18
 Number = 19
 Number = 20
