PHP - Convert Function To Php

I am trying to convert colors from Hex to HSL (Not HSL to Hex). I am using a PHP function for this purpose. But It's not working properly for some colors. For example for #e04c4c the HSL should be (0, 70%, 59%) which it isn't the case with the 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) / $delta) % 6;
    } elseif ($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) * 100;
    $saturation = $delta === 0 ? 0 : ($delta / (1 - abs(2 * $lightness - 1))) * 100;
    if ($saturation < 0) {
        $saturation += 100;
    }

    $lightness = round($lightness);
    $saturation = round($saturation);

    //return "hsl(${hue}, ${saturation}%, ${lightness}%)";
    return array($hue, $saturation, $lightness);
}

This is how I used it:
 

$templatePrimaryColor = '#e04c4c';

$templatePrimaryColor = str_replace("#", "",$templatePrimaryColor);

list($h,$s,$l) = hexToHsl($templatePrimaryColor);

$primaryColor = "hsl(${h}, ${s}%, ${l}%)";

This is the output:

echo '<pre>',print_r(hexToHsl($templatePrimaryColor)).'</pre>';

Array
(
    [0] => 0
    [1] => 99
    [2] => 59
)
1

Does anyone know what is the problem there?

Thank you.

$dir_name="./$masterdir";

$dir = opendir($dir_name);
$basename = basename($dir_name);
$fileArr = array();

while ($file_name = readdir($dir)){
if (preg_match("/\.jpg$/i", $file_name)) {

#Get file modification date...
#
$fName = "$dir_name/$file_name";
$fTime = filemtime($fName);
$fileArr[$file_name] = $fTime;
}
}
# Use arsort to get most recent first
# and asort to get oldest first
arsort($fileArr);

////$numberOfFiles = sizeOf($fileArr);
$numberOfFiles =7;
for($t=0;$t<$numberOfFiles;$t++){
$thisFile = each($fileArr);
$thisName = $thisFile[0];
$thisTime = $thisFile[1];
$thisTime = date("d M y", $thisTime);


echo"$masterdir/$thisName";

}


closedir ($dir);

this returns the latest 7 files in a dir... works fine but each is now deprecated so gives warning

        $cb = 'str_replace("' . $this->LE . '", "", "<$1>");';
        $encoded_value[$key] = preg_replace("/<([^>]+)>/e", $cb, $encoded_value[$key]);

if($_GET['type'] == 'country'){
	$result = mysql_query("SELECT name FROM country where name LIKE '".strtoupper($_GET['name_startsWith'])."%'");	
	$data = array();
	while ($row = mysql_fetch_array($result)) {
		array_push($data, $row['name']);	
	}	
	echo json_encode($data);
}
