PHP Tutorial – While Loops

The PHP language has four different kinds of conditioned loops. In this PHP tutorial we will look at the “while” loop. Loops are used to execute a block of code multiple times.

In PHP, we have the following loop statements:

  • while – loop through a block of code while a specified condition is true
  • do…while – loops through a block of code once, and then repeats the loop as long as a specified condition is true
  • for – loops through a block of code a specified number of times
  • foreach – loops through a block of code for each element in an array


while (condition)
  code that will be executed;

while loop Example

Ok, let’s look at an example:


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


First we set X to 0. Then we enter the loop with; X less or equal to 5. As long as this is true the number will be printed. At the end of the loop we increment X. The loop until X is false (has the number 6.)

So the output of our example will be:

The number is 0
The number is 1
The number is 2
The number is 3
The number is 4
The number is 5

That is all for this php tutorial.
