Hex2RGB

With this function you can convert a normal HEX-color (like #FF00FF) into it's RGB values (Array(179,218,245)).

function Hex2RGB($color){
    $color = str_replace('#', '', $color);
    if (strlen($color) != 6){ return array(0,0,0); }
    $rgb = array();
    for ($x=0;$x<3;$x++){
        $rgb[$x] = hexdec(substr($color,(2*$x),2));
    }
    return $rgb;
}


// Example usage:
print_r(Hex2RGB('#B3DAF5'));

/*
Returns an array (R,G,B):

Array
(
    [0] => 179
    [1] => 218
    [2] => 245
)
*/

// Another cool way to define RGB colors with
// Hex values: (like #B3DAF5)

$rgb = array(0xB3, 0xDA, 0xF5);

print_r($rgb);

/* output:

Array
(
    [0] => 179
    [1] => 218
    [2] => 245
)

*/
