Anyway to see if a url 'consists' something?

Lets say I set a variable,

$lines = file
('http://tibia.4players.de/statistics/?subtopic=whoisonline&world=Nova');

$charname = $_POST['charname'];

if($lines (?consists?) $charname) {
echo "<font color='green'>". $charname ."</font>";
}


Is it possible to see if this homepage consists lets say a Character Name
like in this case?

I am making an online list for my guild's homepage... and I want to see if
someone is online then his/her name should be shown in Green for e.g

If it is, how do I write the script?

Please help me!!! =(

In advance,
Andreas Saarva.

I think you are looking for something like this:

for ($i=0; $i<count($lines);$i++) {
if (stristr ($lines[$i], $charname)) {
str_replace ($charname, "<span style="color:
green;">$charname</span>); }
echo $lines[$i];
}

Case of name may be a problem, so you may want to use eregi_replce
instead.

(BTW, <font> is deprecated. ;-) )
