I am trying to get some information using a parser I am making.

Here is my code
<?php
if (!$_GET['id']) {
die("Please specify a member ID using ?id=1245");
}
$file = file_get_contents("http://zbcode.com/profile/".$_GET['id']);
if (preg_match("/<td>No Member was found/",$file) == 1) die("Member not Found");
preg_match("/<th colspan=\"2\" class=\"l\">(.*?)<\/th>/",$file,$name);
preg_match("/<dt>Posts:<\/dt><dd>(.*?)<\/dd>/",$file,$post);
echo ("Hi $name[1] $post[1]");
?>
However when I run it.. I get :

Notice: Undefined offset: 1 in C:\wamp\www\wekaboard\zbcode.php on line 9
Hi Dorith

Here is what I am trying to get:
<dt>Posts:</dt>
<dd>527</dd>

Where 527 is the number I am getting. Of course, It updates.
Example profile: http://zbcode.com/profile/375164

What am I doing wrong?

try this

<?php
$id = 375164;
$file = file_get_contents("http://zbcode.com/profile/".$id);
if (preg_match("/<td>No Member was found/",$file) == 1) die("Member not Found");
if(preg_match("/<th colspan=\"2\" class=\"l\">(.*?)<\/th>/",$file,$name))
{
if(preg_match("/<dt>Posts:<\/dt><dd>(.*?)<\/dd>/",$file,$post))
{
echo "Hi ".$name[0]." ".$post[0];
}
else
{
echo "Found no posts";
}
}
else
{
echo "couldn't find this thing";
}
?>

or even better

<?php
$id = 375164;
$file = file_get_contents("http://zbcode.com/profile/".$id);
if (preg_match("/<td>No Member was found/",$file) == 1) die("Member not Found");
if(preg_match("/<th colspan=\"2\" class=\"l\">(.*?)<\/th>/",$file,$name))
{
if(preg_match("#<dt>Posts:<\/dt>\s*<dd>(.*)<\/dd>#is",$file,$post))
{
echo "Hi ".$name[0]." ".$post[0];
}
else
{
echo "Found no posts";
echo "<xmp>".$file."</xmp>";
}
}
else
{
echo "couldn't find this thing";
echo "<xmp>".$file."</xmp>";
}
?>

white space occurred between </dt>[[[[[]here[]]]]]<dd> which you didn't take into account. Also using <xmp> to debug is very useful mate!
