PHP Tutorial – The while loop

A loop is a block of code that enables you to repeat the same set of statements or commands over and over again; the actual number of repetitions may be dependent on a number you specify.

The while loop

The while loop will continue to execute a block of code as long as the specified condition is true and if the condition becomes false the code within the loop will not be executed.


while (condition)
code to be executed;


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


The number is 1
The number is 2
The number is 3
The number is 4
The number is 5
The number is 6
The number is 7
The number is 8
The number is 9
The number is 10

In our example we have initialize our $num variable into 1 and the condition is while our $num variable is less than or equal to ten, it will write some output and the loop will continue and it will increase by 1 as the loop runs.
