If you need to calculate the integer representation of a color with an alpha channel, without
initialising an image and using the imagecolorallocatealpha function. Then this function might be of
some help:
<?php
function alphaColor($hexColor,$alpha)
{
return bindec(decbin($alpha).decbin(hexdec($hexColor));
}
echo alphaColor("FFFFFF",127);
?>
