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

You can use the function hexdec(hexStr: String) to get the decimal value of a hexadecimal string.

See below for an example:

$split = str_split("ffffff", 2);
$r = hexdec($split[0]);
$g = hexdec($split[1]);
$b = hexdec($split[2]);
echo "rgb(" . $r . ", " . $g . ", " . $b . ")";

This will print rgb(255, 255, 255)
