I needed some PHP code to randomly generate me a hex value for use as a color in a webpage. Here’s what I came up with (WARNING: Some colors are UGLY!)

function random_hex() {
	$color = '';
	for ($c = 0; $c < 6; $c++) {
		$i = rand(0, 15);
		switch ($i) {
			case 10 :
				$i = 'A';
				break;
			case 11 :
				$i = 'B';
				break;
			case 12 :
				$i = 'C';
				break;
			case 13 :
				$i = 'D';
				break;
			case 14 :
				$i = 'E';
				break;
			case 15 :
				$i = 'F';
				break;
			default :
				$i = $i;
				break;
		}
		$color .= $i;
	}
	$color = '#' . $color;
	return $color;
}
