Regex for matching CSS hex colors

I\'m trying to write regex that extracts all hex colors from CSS code.

This is what I have now:

Code:

$css = <<

        

Answer 1

The accepted answer shows you how to do it with regex, because that was your question. But you really don't need to use regex for this. Normally this is how I would do it:

if(ctype_xdigit($color) && strlen($color)==6){
    // yay, it's a hex color!
}

for 100.000 iterations:

Regex solution *: 0.0802619457245 seconds

Xdigit with strlen: 0.0277080535889 seconds

*: hex: ([a-fA-F0-9]{6})
