With this function you can change a hexadecimal color to a decimal one:
<?php
function hextodec($hex){
$hex=split('#', $hex);
$hex=end($hex);
$dec=array(
"r"=>hexdec(substr($hex, 0, 2)),
"g"=>hexdec(substr($hex, 2, 2)),
"b"=>hexdec(substr($hex, 4, 2))
);
return $dec;
}
//Use this function:
$color=hextodec("#5522ff");
echo $color["r"].', '.$color["g"].',
'.$color["b"];
?>
It returns an array like this
Array(
[r] => 85
[g] => 34
[b] => 255
)
