PHP Auto-Increment and Auto-Decrement Operators

Posted by Daniel at 6:16 am

The auto-increment operator designed to automatically increment the value of the variable it is attached to by 1. It is represented by a double addition symbol (++). To see it in action, run the following script:

<?php
// define $total as 10
$total = 10;
// increment it
$total++;
// $total is now 11

?>

Thus, <?php $total++; ?> is functionally equivalent to <?php
$total = $total + 1; ?>.
There’s also a corresponding auto-decrement operator (––), which does exactly the opposite:

<?php
// define $total as 10
$total = 10;
// decrement it
$total--;
// $total is now 9

?>

These operators are frequently used in loops to update the value of the loop counter.
