$text=preg_replace_callback('/\[([A-Za-z0-9\'.-:underscore:]+)\|([A-Za-z0-9\'. -:underscore:]+)\]/i' , "findLinks", $text); This regex should match any pair of square brackets, with two bits of text between them seperated by a pipe, like these: [Ety|wife] [Jarred|brother] [Ahmed|neighbor] [Gili and Gush|pets] [Bill Clinton|horny] I would expect that the "." would match spaces, but it doesn't. So the first three examples that I've shown are matched, but the last two are not. I've even added "\w", "\s", " ", and ":space:" to the regex, but of course that's not matching, either. What am I doing wrong? Note that I've been honing my regex skills for the past few days, but I've not so much experience with them. Thanks in advance to whoever can help me understand this.

Dotan, I'm surmising what you really want to do is grab all the characters between [ and | for the first field, and everything from | to ] as the second field. I would therefore identify the first field with:

        [^\]|]
        anything except the close-bracket and the vertical pipe

and the second field with:

        [^\]]
        anything except the close-bracket

Therefore:

        /\[([^\]|]+)\|([^\]]+)\]/
