404 Error Reporting

This Custom 404 PHP script will display an error page and send you an email with all the relevant information when there is a 404 error.  It is useful for notifying you of bad links to your site and it is also a great debugging tool, notifying you of your own invalid references.  You may want to turn on the email feature selectively (for testing your site and/or periodic checks) rather than leave it on all the time as it could generate a lot of emails if someone keeps making bad requests.

In order to use it you must add the following line to your .htaccess file.  DO NOT use the full URL to the error page, use the relative path as done in the example below.

ErrorDocument 404 /404.php

Raisonnement, la résolution de problèmes

Tracking and Securing Downloads

If you want to report or track downloads from your website, try this script.   This script will send you an email every time you have a download.   The email will tell you what file was downloaded and who did the download.   You could change this script to keep counts (store them in flat file or MySQL) if you desire. The variable $directory is the directory where the download files are located.   If you want the script in the same directory as the files then use "./" as the directory (you must always have the slash). In your html page, use the following structure as your download link (where name.txt is the file name to download): <a href="download.php?file=name.txt">download</a> Then you use the following script (called download.php): - - Start Script Here - - <?php $emailaddress  =  "email@yourdomain.com" ; $filename  =  $_GET [ 'file' ]; $directory  =  "downloads/" ; $path  =  "$directory$filename" ; putenv (...
