Convert hex color to RGB values in PHP

Question

What would be a good way to convert hex color values like #ffffff into the single RGB values 255 255 255 using PHP?

Answer 1

If you want to convert hex to rgb you can use sscanf:

<?php $hex = "#ff9900"; list($r, $g, $b) = sscanf($hex, "#%02x%02x%02x"); echo "$hex -> $r $g $b"; ?> 

Output:

#ff9900 -> 255 153 0
