You have the anwser in the error code, regex needs delimiters to work.

And you should use str_replace for  .

The first character in your pattern is interpreted as a delimiter and right now PHP thinks you want to use & as a delimiter. In your first regex, the delimiter was ', BTW. I guess what you really want is not ' ', but '/ /' (e.g. for pattern 2), now / is the delimiter (it is not part of the regex itself). BTW, your first regex seems not correct either, it should probably be

'<style[^>]*>[^<]*</style>'

Otherwise the regex could match the first tag and the very last tag of the whole document.
