livethedead Posted February 12, 2012 Share Posted February 12, 2012 I can't figure out why this isn't working. <?php $twitter = trim($_REQUEST['twitter_handle']); if (preg_match("/^@/", $twitter)) { preg_replace("/@/", "twitter.com/", $twitter); } else { $twitter = "twitter.com/" + $twitter; } <? if I enter @asdjf it just returns @asdjf. Appreciate any help. Quote Link to comment Share on other sites More sharing options...
ragax Posted February 12, 2012 Share Posted February 12, 2012 Hi livethedead, It sounds like it could be an encoding problem, where what you see is not what you think it is. Before your preg_match, try running this to see the actual components of the string. If there is something odd, it should jump out. for($i=0;$i<strlen($twitter);$i++) echo "{{$twitter[$i]}}" . ord($twitter[$i]) . " <br />\n"; Quote Link to comment Share on other sites More sharing options...
livethedead Posted February 12, 2012 Author Share Posted February 12, 2012 edit: I occidentally added a character, it's working now. {@}64 {p}112 {h}104 {p}112 @php The script isn't from pratical use, I'm just teaching myself PHP. After finishing a chapter in this book on regular expressions a snippet suggested to rewrite an old script using regex. I've been sitting here for about and hour self-proclaiming there is nothing wrong with this code haha. I would like to figure out what's wrong, for future reference. I appreciate your helping.

AyKay47 Posted February 13, 2012 Share Posted February 13, 2012 Actually, I haven't lol. i have no idea what to do with those values. what do you mean?

livethedead Posted February 13, 2012 Author Share Posted February 13, 2012 I'm still having the original problem, I used the code mentioned above but not sure exactly what to do with the results in the process of solving the problem. My edit in the second post is misleading, didn't realise that until just now, I was referring to the code he gave me. Quote Link to comment Share on other sites More sharing options...
ragax Posted February 13, 2012 Share Posted February 13, 2012 Sorry, I missed the original problem. Use $twitter=preg_replace( etc That will fix it. Here is a working example. <?php $twitter = '@whatever'; if (preg_match("/^@/", $twitter)) { $twitter=preg_replace('/@/','twitter.com/',$twitter); } else { $twitter = "twitter.com/".$twitter; } echo $twitter.'<br />'; ?> Quote Link to comment Share on other sites More sharing options...

ragax Posted February 13, 2012 Share Posted February 13, 2012 You're welcome, glad it works. And sorry for taking you in another direction originally, I too missed it on first glance. Quote Link to comment Share on other sites More sharing options...
