Random Code(Color Hex Generator)

Gavin Wednesday 21st June 2023, 17:58:14

I don't know why I am doing this, but I have made a custom HEX color generator

<?php
//$loop is how many generated hex code you would want to have.
function genHex(int $loop):array {
			$hex = array();
			$list = '0123456789abcdef';
			for($i=0;$i<$loop;$i++){
				$h='#';
				for($k=0;$k<6;$k++){
					$rand = rand(0,strlen($list)-1);
					$l = str_split($list);
					$h.=$l[$rand];
				}
				$hex[$h] = $h;
			}
			return $hex;
		}
?>

That's great, but you can do it more simply like this 😄 :


function genHex(int $loop): array {
    $hexArray = [];
    
    for ($i = 0; $i < $loop; $i++) {
        $hexArray[] = sprintf('#%06X', mt_rand(0, 0xFFFFFF));
    }
    
    return $hexArray;
}
