Question

Alright  so I m currently working on parsing an RSS feed  I ve gotten the data I need no problem  and all I have left is parsing the game title   Here is the code I currently have  ignore the sloppiness  it is just a proof of concept     lt  php  url    http   raptr com conexion rss     ch   curl init    curl setopt  ch  CURLOPT URL   url   curl setopt  ch  CURLOPT RETURNTRANSFER  1     result   curl exec  ch    curl close  ch     xml   new SimpleXMLElement  result     lastgame    xml- gt channel- gt item 0 - gt description  preg match   a-zA-Z   lt  a gt       lastgame   match    echo  match    gt    Everything was working great  but then I started getting this error   Warning  preg match    function preg-match    Unknown modifier     in raptr php on line 14   The only thing I have left is to strip out the closing anchor tag and the period  but I can t seem to figure out why it isn t liking the      Any ideas   Edit  This should not be marked as a duplicate as it was asked two years before the other question

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
