Is there a PHP port of Java's Matcher class?

I'm porting YUI's CssCompressor, which has several Matcher uses, to PHP. For the sake of long-term maintenance I'd like to keep the PHP port as similar to the Java original as possible (preg_replace_callback of course works, but d开发者_Python百科rastically changes the program flow).

So, has anyone ported Matcher to PHP?

Are you looking for the while(find next match){ do stuff } equivalent in PHP (without using preg_match_all)?

In that case use preg_match with the offset parameter. For example:

offset = 0;
while(preg_match(re, str, matches, PREG_OFFSET_CAPTURE, offset)){
    offset = matches[0][1] + strlen(matches[0][0]);

    // do stuff
}
