i have got this preg replace that always returns the value with 1

\\1 doesnt seem to work.

the function is Get_Username2($id);

help please

PHP Code:

$out1 = preg_replace("/\[user\](.*)\[\/user\]/Usi", "".Get_Username2('\\1')."", $out1); 


I'm not sure what you are trying to do. You are calling Get_Username2 with the parameter '\\1' and appending it to two empty strings (which has no effect by the way). What does get_username do? what do you expect this expression to do?

You should take a closer look at the preg_replace documentation: http://us2.php.net/manual/en/function.preg-replace.php

here is the entire code for the page.

PHP Code:

<?
$conn = mysql_connect("localhost","auto","password");
$db = mysql_select_db("tableA");
function Get_Username2($id){
 $result = mysql_query("SELECT * FROM `grpgusers` WHERE `id` = '".$id."'");
 $worked = mysql_fetch_array($result);
        $bbuser = New User($worked['id']);
  $secondsago = time() - $bbuser->lastactive;
        if($secondsago<=900){
 return "<table width='55%' background='http://i48.tinypic.com/15zp0tc.gif'><tr><td width='40%'>".$bbuser->formattedname."</td><td width='15%'>".$bbuser->level."</td><td width='10%'>".$bbuser->cityname."</td></tr><tr><td><center>&nbsp; <a href=spy.php?id=".$worked['id'].">Spy</a></center></td><td> <a href=mug.php?id=".$worked['id'].">Mug</a></td><td width='33%'>&nbsp;&nbsp;&nbsp; <a href=attack.php?id=".$worked['id'].">Attack</a></td></tr></table>";
        }
        if($secondsago>=900){
 return "<table width='55%' background='http://i48.tinypic.com/2i12rmx.gif'><tr><td width='40%'>".$bbuser->formattedname."</td><td width='15%'>".$bbuser->level."</td><td width='10%'>".$bbuser->cityname."</td></tr><tr><td><center>&nbsp; <a href=spy.php?id=".$worked['id'].">Spy</a></center></td><td> <a href=mug.php?id=".$worked['id'].">Mug</a></td><td width='33%'>&nbsp;&nbsp;&nbsp; <a href=attack.php?id=".$worked['id'].">Attack</a></td></tr></table>";
        }

?>

the replacement in the preg replace is a function and it will notbackreference properly.

the preg replace does notbackreference properly

Try:

PHP Code:

$out1 = preg_replace("/\[user\](.*)\[\/user\]/esi", "Get_Username2('\\1')", $out1); 


well, i got no error message, just page errors and no result.

please can someone explain why this isnt working or how to fix this. this is important to me.

the

PHP Code:

"".Get_Username2('\\1')."", 


is what wont work.

PHP Code:

$out1 = preg_replace("/\[user\](.*)\[\/user\]/Usi", "".Get_Username2('\\1')."", $out1); 


You have to pass the "e" modifier flag in order to evaluate the replace function, and the function must be written as a string (much like you would do using an eval function).

um, how might i do that exactly. im new with this preg replace.

never mind i got this thank you alot.
