In this tutorial, we are going to look at a "while" loop. This loop executes a block of code as long as the specified condition is true. We could use this for counting so it does X 5 times etc.
A while loop looks like this :
<?php
$x=0;
while($x<6) {
echo $x;
$x++;
}
?>
In here, a variable of x is assigned with the value 0. The while look says : while the variable x ($x) is less than 5 (<5)
Echo (print) out the variable.
Add 1 to the x variable.
So what you should get printed out is :
1
2
3
4
5
This is useful for a number of things in PHP.
