Filter to omit based on certain url

[mherzber]

I have a script that will send an error for 404 emails. I want to exclude urls from a certain directory. How can I make it so they wont submit if /example is in the url? The code works fine I just want to filter out. Also you will see that I have defined REQUEST_URI this is because I have php on IIS, not my choice. I am somewhat of a noob, so if you can make your answer as simple as possible I would really appreciate it. Here is code:

 

<?
# 404.php - Last updated 3/1/2002, initially released 8/10/2000
# Trap 404 errors and mail a notice to the webmaster
# Now requires PHP4
# Copyright 2000-2002 shaun@shat.net under the GPL v2+

# Set these variables to configure the script:
if (!isset($_SERVER['REQUEST_URI']))
{
    if (!isset($_SERVER['QUERY_STRING']))
    {
        $_SERVER['REQUEST_URI'] = $_SERVER["SCRIPT_NAME"];
    }
    else
    {
        $_SERVER['REQUEST_URI'] = $_SERVER["SCRIPT_NAME"] .'?'.
        $_SERVER['QUERY_STRING'];
    }
}


# Set $domain to your domain name (no www)
$domain = "example.com";

# Set $docroot to the URL of the directory which contains your
# .htaccess file. Don't include trailing slash.
$docroot = "http://www.example.com";

# Font face you'd like to use on the 404 page
$fontface = "Verdana";

# Font size you'd like to use on the 404 page
$fontsize = "2";

# Background color of the 404 page (default is white)
$bgcolor = "#ffffff";

# Text color you'd like to use on the 404 page (default is black)
$textcolor = "#000000";

# This script is capable of mailing the details of each 404 error
# to the webmaster. Use the $reportlevel variable to control when
# you receive these reports.
#
# 0 = don't use the email capabilities
# 1 = send email only if the error's referer contains your domain name
#     (i.e. the 404 was generated by a broken link on your site)
# 2 = send email any time a 404 error is generated (useful for tracking
#     broken links at other sites which link to you)

$reportlevel = 1;

# Set $emailaddress to the email address of whoever should be
# notified of 404 errors. Don't escape the @ symbol.
# You can leave this unassigned if you're not using email features.

$emailaddress = "me@example.com";

#
#Configuration ends here!
#

#Until I rewrite my scripts, this will suffice for bg-compatibility;
if(phpversion() >= "4.2.0"){
   extract($_POST);
   extract($_SERVER);
   extract($_ENV);
}


# The send_email function sends the details of the 404 error to the
# webmaster. 

function send_email(){
   # Request access to the global variables we need
   global $REQUEST_URI, $HTTP_REFERER, $emailaddress, $REMOTE_ADDR, $docroot;

   # Build the $errortime variable to contain the date/time of the error.
   $errortime = (date("d M Y h:m:s")); 

   # Create the body of the email message
   $message .= "404 Error Report\n\nA 404 error was encountered by $REMOTE_ADDR";
   $message .= " on $errortime.\n\n";
   $message .= "The URI which generated the error is: \n$docroot$REQUEST_URI\n\n";
   $message .= "The referring page was:\n$HTTP_REFERER\n\n";

   # Send the mail message. This assumes mail() will work on your system!
   $headers = "From: $emailaddress\nDate: $errortime -0600\n";
   $subject = "404 Error Report";
   mail($emailaddress, $subject, $message, $headers);
   
   return;
  }

# Done with function declarations. Main function begins here.
header("404 Not Found");


# See whether or not we should send an email report. If so, do it.
if ($reportlevel != 0)
  if ($reportlevel == 1) {
    if (eregi($domain,$HTTP_REFERER))   
      send_email(); }
  else
     send_email();
