The do-while loop is very similar to the while loop, but it does things in reverse order. The mechanism of the while loop is - while a condition is true, perform a certain action. The mechanism of the do-while loop is - perform a certain action while a condition is true.
Syntax:
do{ // execute this code; } while (condition);
Example:
<?php $num = 0; do{ $num = $num + 5; print $num . "<br />"; } while ($num < 25); ?>
Output:
This will produce the following result
5 10 15 20 25
Flow chart
In the above code, a variable named num is initialized with the value of 5. The condition in the do-while loop is that while num is less than 25, 5 should be added to num. Once the value of num is greater than 25, the loop will stop executing.
