PHP Question... Need some help

agamer

Ok, I made a tagboard for my site, and am trying to get /me coding in it, the problem, I don't know how to get a variables contents, check if it exists and if so, etc

What i'm trying to do, is read the data in "$message".

Check if "/me" exists somewhere in it, and if so, make $username2 = "<font color=ffffff>$username</font>";

insted of #000000 for font color, default.

How would I go about doing this?

I'm currently useing if's and else if's, but this one has me baffled.

Thanks.

You've lost me m8. Are you trying to echo back declared variables?

I'm guessing a tagboard is something like a comments system, or bulletin board/guestbook type of thing.

Anyway, we need more info. Post a part of your code so we can see exactly what you're doing.

It seems to me like what you're looking for is regular expressions. Read this page and see if you can find your answer here: http://www.php.net/manual/en/ref.regex.php

To get the contents of a variable, just use it. To see if a variable exists, use isset().

But I think your question is really "how do I find out if a string contains a particular substring"?

[man]strpos[/man] can be used to check this, and I don't know what you're talking about for the rest of it, but see the other string functions listed on that manual page.

while ($row = mysql_fetch_array($results))
{
$nick = $row["nick"];
$url = $row["url"];
$message = $row["message"];
$datetime = $row["datetime"];

    /* Add Emoticons to the user's message */
    if ($emoticon=="1" or $emoticon=="y") 
    $outcode = ti_code($message);
    $usrmsg = "$outcode";

    if ($url=="" or $url=="http://") 
      $nick = "<br><B>$nick";
    else 
      $nick = "<br><B><a href=\"$url\" target=\"_blank\">$nick</a>";

    if ($timestamping == 1)

      echo "    $nick ($datetime)$spacer</B> $usrmsg<BR>\n";
    else
      echo "    $nick$spacer</B> $usrmsg<BR>\n";
  }

  mysql_close($connection);

That's how it get's displayed.

I'm trying to get PHP to read the information (text) contained in $message, then see if the $message contents have a /me to start with, in IRC scripts, it makes the usernames like...

***Name is useing /me

with a different font color, i'm trying to get it to read $message, if it includes /me, then to alter the username and message so that insted of it doing:

      echo "    $nick$spacer</B> $usrmsg<BR>\n";

I want it to do this insted:

      echo "    <font color=FFFFFF>***$nick$spacer</B> $usrmsg *</font><BR>\n";

hope that explains it better

***edit:

Oh yea, a tagboard is a small chat type thing that can be put on the side of a site so user's can chat back and forth while browseing it.

Sort of a Mini Chat, but without the big link and window.

***edit2:

I checked out the link coditoergosum posted,

i'm pretty sure

ereg ("abc", $string);

/ Returns true if"abc"
is found anywhere in $string. /

is what i'm looking for, however, I don't know how to use it or where it would go in the code. or how it's used.

Well, if you just want to see if the first three characters of a string are "/me" then you can just use [man]substr()[/man] to get the first three characters of a string and see if they make "/me".

Duey

or if you wanted to check all the chars you would use one of strstr() strpos() and so on theres lots of them

agamer

I'm not really a php guru, lol

could somebody please explain/tell me exactly how to do this, or what the code that i'd use for my tagboard?

thanks.

Weedpacket

Nah, I think I'll just say RTFM.

agamer
