Debug apache log files from php

This is a secure method to debug your apache from within php

For debugging without checking error_log/access_log files

  1. create a file called phpinfo.php in your / directory
  2. the contents of phpinfo.php

  3. Use this for your .htaccess file.

    Options +FollowSymLinks
    ErrorDocument 404 /phpinfo.php

Now instead of getting a 404 error you will see debug information which will help you find out what the problem is.
