[rps-include post=6522]

In previous chapter we have looked for and foreach loops. In this chapter we will look another Php programming language loop while and do while loops.

While Loop

while loop iterates over given code block unless the condition met. The condition is checked in before every step. If the condition do not meet the while loop will end. Syntax is like below.

  • CONDITION is checked after every step
  • CODE will run in every step

In this example we will count from 1 to 10 and use variable named $counter and increase it in every step.

If we run code above we will get following output. The name of the code file is index3.php

Do While Loop
