Increment Hex Values

increment-hex-values.php

<?php
// This file increments hex values and keeps any leading zeroes.
// Example: Use to generate a list of MySQL CREATE DATABASE functions to set up database shards.

$x = 0; // Counter
$hex = "00"; // When the amount of digits changes in $hex, remember to change the str_pad() function, too.

while ($x < 256) { // The amount of times to loop.
	echo "$hex <br />";
	$hex = dechex(hexdec($hex)+1); // Increment the hex value.
	$hex = str_pad($hex, 2, "0", STR_PAD_LEFT); // Keep leading zeroes up to 2 digits.
	$x ++; // Counter
}
