Do-while Loop:

 

Do-while loop is a control flow statement it is also called do-loop. It must run the code once and then checks the condition and repeat the loop if the condition is true otherwise terminate the loop.

 

Do-while Loop in PHP:

 

When we want to run our code at least once whatever the condition is we use do-while loop because it must execute the code one time and then checks the condition and response according to the condition. In the given code we initialize variable i with 1 and then in do block increment i and print it. This do block must execute at least once then it has to check the given condition that is if variable i is less then and equal to 5.

 

Syntax:

 

do

 {

code to be executed;

}

while (condition);

 

Code:

 

<?php

$i=1;

do

  {

  $i++;

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

  }

while ($i<=5);

?>
