excluding text

[ice2003]

This is getting to me , what i am doing is pulling some info from my sql base , some of the info that is comming out i want to exclude with php , this is what i am using and it works to omit data but only the excat data , is it possibel to add a wildcard that excludes all data say beginning with guest.

$find[] = 'Guest4521'; 
$replace[] = '';
$text = str_replace($find, $replace, $str);

see what i mean it will omit the data Guest4521 but i want it to omit all data begining with guest.

Any ideas would be very helpful.

edit , almost got it with this but its just removing the Guest bit and not the numbers after it.

$irc18 = preg_replace("/Guest(.*?)/", "", $ircusers);

What about:

 $irc18 = preg_replace("#^(guest[0-9]+)(.*)$#i", "\\2", $ircusers);

nope thanks for trying though now the word Guest has come back as well.

Are you sure?

<?php
  $ircusers = "Guest1325342google";
  $irc18 = preg_replace("#^(guest[0-9]+)(.*)$#i", "\\2", $ircusers); 
  echo $irc18;
?>

yup sorry , what i am doing is pulling a list of names out of sql which is a list of names in a chat room , $ircusers is the list of names returned by sql.

Are you using a string with all of the names in it or are you using an array to hold all of the names?

Can you post some of your code where you are using this?

[ice2003]

this is the code i am using to grab the info from sql

$irc = "select online, online_max, operators, halfops, voiced, users, topic from irc_channel ORDER BY users DESC";
$irc1 = mysql_query_eval($irc,$link);
$irc2 = mysql_fetch_array($irc1);
$irconline=number_format($irc2['online']);
$irconlinemax=number_format($irc2['online_max']);
$ircoperators = ($irc2['operators']);
$ircvoiced = ($irc2['voiced']);
$ircusers = ($irc2['users']);
$irctopic = ($irc2['topic']);
mysql_free_result($irc1);

$irc18 = preg_replace("#^(guest[0-9]+)(.*)$#i", "\\2", $ircusers);

[Kudose]

Are the Operators and Users an array of names logged in? If so, what are they delimited by?

[ice2003]

all the info is stored in one table and users is
users text NOT NULL,

*edit , looks like its in an array as it arrives from the channel
also looks like delimited by cr (i think)
correction i think its just a space inbetween names.

Hi,

in your first post you need to add the word delimiter (space|end of string|....), something like

$irc18 = preg_replace("/Guest.*?( |$)/i", "", $ircusers); 

because without the delimiter the (.*?) part would match the shortest string that comes after guest and that's an ampty string.

Remove the i modifier if you want to be case sensitive.
