Eric Scheid (founder of the excellent IAWiki) shot me a line with a more efficient and much sleeker version of my random hex code straight after I posted it, so here it is!
function random_hex() {
$color = '';
for ($c = 0; $c < 6; $c++) {
$i = rand(0, 15);
$color .= substr("0123456789ABCDEF", $i, 1)
}
$color = '#' . $color;
return $color;
}
Thanks Eric!
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;
}
