Try this code   preg match    a-zA-Z   lt   a gt        lastgame   match   print r  match     Using   as a delimiter means you also need to escape it here  like so   lt   a     UPDATE  preg match    lt a   lt a   gt      lt      lastgame   match   echo     match 1         Might not be the best way

You need to use delimiters with regexes in PHP  You can use the often used    but PHP lets you use any matching characters  so   and   are popular   Further Reading   If you are interpolating variables inside your regex  be sure to pass the delimiter you chose as the second argument to preg quote

This happened to me because I put a variable in the regex and sometimes its string value included a slash  Solution  preg quote
