Find something in CSS with PHP

I am extracting a css file from PHP in my database.

So I have: $mycss = "SOME CSS SOME CSS SOME CSS"

In this $ mycss, I can:

 div.coul01,.red,.coul01{ color:#663333; } div.coul02,.blue,.coul02{ color:#3366CC; }

In this example, I need to extract PHP, for each instruction starting with a div. the second element, here is red and blue.

Do you have any ideas? Thanks!

If you really don't want to use any library and want to stick with regular expressions, this will work for you:

 <?php $mycss = "body,div.coul01,.white,.coul01{ color:#000000; } div.coul01,.red,.coul01{ color:#663333; } div.coul02,.blue,.coul02{ color:#3366CC; } div.coul02,.grey,.coul02{ color:#C0C0C0; }"; preg_match_all("/^div\.[^,{]*,[\.#](\w+)/ms", $mycss, $matches, PREG_PATTERN_ORDER, 0); ?>

and then in your $matches variable you will have something like this:

 $matches[0][0] div.coul01,.red $matches[0][1] div.coul02,.blue $matches[0][2] div.coul02,.grey $matches[1][0] red $matches[1][1] blue $matches[1][2] grey

$matches[1] is what you are looking for

You can use explode() with a comma as a separator, but a more elegant solution would be to use a PHP CSS parser, for example https://github.com/sabberworm/PHP-CSS-Parser

It is more flexible.

I would suggest using a CSS parser like Sabberworm . You can also try this library , which I saw when some people recommend. There is also a PEAR package, which you can see on the HTML_CSS name. Please note that it is not currently supported. Personally, I would stay away from writing custom regex expressions for this kind of thing, simply because I saw projects like “take wings” and lead to messy program code that is hard to maintain as the project expands and additional features are added . In one minute, you want everything that starts with a div, and then you want to control the h1, span, and p styles.
