D'oh! I knew it should be substr but I could never find it! I was up to
page 1098 or such and muddling through all of the PCRE doc when I g
$color = '#aabbcc';
if (strlen($color) == 7) {
echo ' r: ' . substr($color, 1, 2);
echo ' g: ' . substr($color, 3, 2);
echo ' b: ' . substr($color, 5, 2);
} elseif (strlen($color) == 4) {
echo ' r: ' . str_repeat(substr($color, 1, 1), 2);
echo ' g: ' . str_repeat(substr($color, 2, 1
3 matches
