# 404.php, 8/10/2000.
# Traps 404 errors and mails a notice to the webmaster.
# Requires PHP 3.0 or newer, and mail capability on your system.

# Disclaimer: I wrote this script for me, and it works for me.
# If it doesnt work for you, or makes your server explode,
# thats life. Please email with questions or bug reports.

# Set these variables to configure the script:

# Set $domain to your domain name (no www)

$domain = "your.domain.com";

# Set $docroot to the URL of the directory which contains your
# .htaccess file. Dont include trailing slash.

$docroot = "http://your.domain.com";

# Font face youd like to use on the 404 page

$fontface = "Verdana";

# Font size youd like to use on the 404 page

$fontsize = "2";

# Background color of the 404 page (default is white)

$bgcolor = "#ffffff";

# Text color youd 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 = dont use the email capabilities at all
# 1 = send email only if the errors 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 = 2;

# Set $emailaddress to the email address of whoever should be
# notified of 404 errors. Dont escape the @ symbol. This will also
# be used as the "from" address on any emails the script generates.
# You can leave this unassigned if youre not using email features.

$emailaddress = "you@your.domain.com";

# The print_details function is what prints the 404 error to
# the visitor. As far as I know, PHP3 doesnt incorporate Perls
# print <<"EOT" ability. PHP4 does allow this capability
# but the script was written for PHP3. So, you have to use
# a lot of echo statements if you want to retain PHP3 compat.

function print_details()
{
# Request access to the global variables we need
global $fontface, $fontsize, $docroot, $REQUEST_URI, $reportlevel;
global $bgcolor, $textcolor

# Print the 404 error in web format
echo "

echo "Were sorry. The page you requested, $docroot$REQUEST_URI, doesnt exist";

# If an email report is being generated, let the visitor know:
