# Common Pitfalls

The MAX_FILE_SIZE item cannot specify a file size greater than the file size that has been set in the upload_max_filesize in the PHP 3.ini file or the corresponding php3_upload_max_filesize Apache .conf directive. The default is 2 Megabytes.

Not validating which file you operate on may mean that users can access sensitive information in other directories.

Please note that the CERN httpd seems to strip off everything starting at the first whitespace in the content-type mime header it gets from the client. As long as this is the case, CERN httpd will not support the file upload feature.
