@hube2 also I tried this part of function :
function hexToHsl($hex){
$red = hexdec(substr($hex, 0, 2)) / 255;
$green = hexdec(substr($hex, 2, 2)) / 255;
$blue = hexdec(substr($hex, 4, 2)) / 255;
$cmin = min($red, $green, $blue);
$cmax = max($red, $green, $blue);
$delta = $cmax - $cmin;
if ($delta == 0) {
$hue = 0;
} elseif ($cmax === $red) {
$hue = (($green - $blue) / $delta);
} elseif ($cmax === $green) {
$hue = ($blue - $red) / $delta + 2;
} else {
$hue = ($red - $green) / $delta + 4;
}
$hue = round($hue * 60);
if ($hue < 0) {
$hue += 360;
}
$lightness = (($cmax + $cmin) / 2);
$saturation = $delta === 0 ? 0 : ($delta / (1 - abs(2 * $lightness - 1)));
if ($saturation < 0) {
$saturation += 1;
}
$lightness = round($lightness*100);
$saturation = round($saturation*100);
// return "hsl(${hue}, ${saturation}%, ${lightness}%)";
return array($hue, $saturation, $lightness);
}
I called as <?php echo hexToHsl($hex_color); ?>
and it returns me an Array
without any kind of result.
Every part of the solution is welcome.
Thanks.
