What is the best way to convert a hexadecimal color value to separate RGB values in PHP?

To convert a hexadecimal color value to separate RGB values in PHP, you can use the `hexdec()` function to convert the hexadecimal value to decimal, then use bit-shifting and bitwise operations to extract the red, green, and blue values. Finally, you can output the RGB values in an array or separate variables for further use. 

$hexColor = "#ff4500";
$hexColor = ltrim($hexColor, '#');
$red = hexdec(substr($hexColor, 0, 2));
$green = hexdec(substr($hexColor, 2, 2));
$blue = hexdec(substr($hexColor, 4, 2));

echo "Red: $red, Green: $green, Blue: $blue";
