            $opacity = 1;
        }else{
            $opacity = "0.$opacity";
        }

        $a = $opacity;
    }

    else{
        return "Error color code! Please enter correct color code, for example #ffffff";
        return false;

    return $r.", ".$g.", ".$b.", ".$a;

}

Usage:

$color = "#167ac6"; // Color Code

$opacity = "50"; // Opacity Value (number inside quotation marks), default is 100 (100 is no opacity).

echo Qassim_HEX_To_RGBA($color, $opacity); // Get RGBA Color!

CSS Example:

<style type="text/css">
    body{
        background-color: rgba(<?php echo Qassim_HEX_To_RGBA("#167ac6", "08"); ?>);
    }
</style>

Note

In opacity value don’t enter direct number like this 03! enter number inside quotation marks like this “03”.
