loops are used to enable code reusability, I mean if you need certain lines of code to be executed repeatedly you should use loops to reduce line of code. our topic of discussion is the difference between For loop and for each loop in PHP, let’s explore both one by one in detail.

syntax and example of for loop:

<?php

//example 
for ($i=5; $i>=0;$i--)
{
echo "number in decreasing order:$i <br>";
}
?>
