[PHP] Re: Convert a grayscale value to a #RRGGBB hex value
If you know its grayscale...
function GrayScaleToHex( $val ) {
$norm = $val * 2.55 + $val/100;
$hex = sprintf("%02X", $norm);
return '#' . $hex . $hex . $hex;
}
Should get you close enough.

[PHP] Re: Classes Constructor syntax
PHP does not support multiple constructors. But, It does support
variable argument lists, so you can fake it with func_get_args() and
func_get_num_args():
function issue() {
if( func_get_num_args() > 0 ) {
$args = func_get_args()
} else {
// do something else...
}
}

[PHP] Re: Image functions
You won't get very far if you aren't outputting an image to the browser
using ImageJpeg(), etc.
