[PHP]While and For loops

TehByte · Aug 29, 2010

The while loop executes a block of code while a condition is true.

Code:

&lt;?php
$i=0;
while($i &lt; 3) {
echo "Your number is: " .$i. "&lt;br /&gt;";
$i++;
}
?&gt;

In this code, while the variable $i is less than 3 the while loop shall run, and the output shall be:

Code:

Your number is 0
Your number is 1
Your number is 2
Your number is 3

The for loop is used when you know how many times your script should run.

Code:

&lt;?php
for($i=0; $i&lt;=5; $i++) {
echo "Your number is: " .$i. "&lt;br /&gt;";
$i++;
}
?&gt;

This example defines a loop with the variable $i=0. The loop shall continue to run as long as $i is less than or equal to 5.

Output:

Code:

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