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

function RGB($hex = '')
{
    $hex = str_replace('#', '', $hex);
    if(strlen($hex) > 3) $color = str_split($hex, 2);
    else $color = str_split($hex);
    return [hexdec($color[0]), hexdec($color[1]), hexdec($color[2])];
}
