Perl has Regexp::Optimizer, is there anything similar in PHP? My searches haven’t turned up anything.

For example, Regexp::Optimizer would turn

/foobar|fooxar|foozap/

into

/foo(?:[bx]ar|zap)/

Update: I wanted to keep that question really short so that people would not try to over-interpret it but it turns out it had the opposite effect. I am looking for something that takes a regular expression and outputs a functionally equivalent yet more efficient regular expression. I have found such a thing in Perl but none in PHP, and I am wondering whether such a thing exists. In that respect, I expect a yes/no answer, accompagnied with a link if applicable. Thanks and sorry for the confusion.

    So as it turns out, there is no generic regular expression optimizer for PHP as of December 1st, 2010.
