I have a script which has this regex in it:
preg_match_all('/((#?[A-Za-z0-9]+))/'
This takes a line of text like and strips out all the characters apart from the color code. For example it turns this:
Black (#000000)
into this:
#000000
I would like to change it so that instead of extracting the color it would extract anything included in the brackets. For example it would turn this:
Black (/magento/1.gif)
into this:
/magento/1.gif
Thanks!
preg_match('/\w+\s*\((.+)\)/', 'Black (/magento/1.gif)', $capture);
var_dump($capture);giving:
array(2) {
[0]=>
string(22) "Black (/magento/1.gif)"
[1]=>
string(14) "/magento/1.gif"
}

$length = strlen($string);
$right = strrpos($string, "(");
$left = strrchr($string, ")");
$start = $right - $length;

$value = substr($string, $start, $end);
echo $value;

There are problems with this pattern if there's a ( before or after your (), but in the case of style sheets, I think not.
