The PHP for Loop
The for loop is used when you know in advance how many times the script should run.
Syntax

code to be executed for each iteration;
}

Examples
The example below displays the numbers from 0 to 10:
Example Explained
- $x = 0; - Initialize the loop counter ($x), and set the start value to 0
- $x <= 10; - Continue the loop as long as $x is less than or equal to 10
- $x++ - Increase the loop counter value by 1 for each iteration
This example counts to 100 by tens:
Example
<?php
for ($x = 0; $x <= 100; $x+=10) {
