<?php// BigDump ver. 0.21b from 2005-02-08
// Staggered import of an large MySQL Dump (like phpMyAdmin 2.x Dump)
// Even through the webservers with hard runtime limit and those in safe mode
// Works fine with Internet Explorer 6.0 SP1, Mozilla 1.x and even Netscape 4.8

// terms of the GNU General Public License as published by the Free Software Foundation;
// either version 2 of the License, or (at your option) any later version.
// THIS SCRIPT IS PROVIDED AS IS, WITHOUT ANY WARRANTY OR GUARANTEE OF ANY KIND
// USAGE:
// 1. Adjust the database configuration in this file
// 2. Drop the old tables on the target database if your dump doesn't contain "DROP TABLE"
// 3. Create the working directory (e.g. dump) on your web-server
// 4. If you want to upload the dump files directly from the web-browser give the scripts
// writing permissions on the working directory (chmod 777 on a Linux based system)
// 5. Upload bigdump.php and your dump files (.sql, .gz) via FTP to the working directory
// 6. Run the bigdump.php from your browser via URL like http://www.yourdomain.com/dump/bigdump.php
// 7. BigDump will start the next import session automatically if you enable the JavaScript
// 8. Wait for the script to finish, do not close the browser window
// 9. IMPORTANT: Remove bigdump.php and your dump files from the web-server
// If Timeout errors still occure you may need to adjust the $linepersession setting in this file

$delaypersession = 0; // You can specify a sleep time in milliseconds after each session
// Works only if JavaScript is activated. Use to reduce server overrun
// Allowed comment delimiters: lines starting with these strings will be dropped by BigDump
