BigDump: Staggered MySQL Dump Importer. Allows you to import large mysql dump files in a staggered way. Stolen from: http://www.ozerov.de/bigdump/ version 0.35
Raw

error_reporting(E_ALL);
// BigDump ver. 0.35b from 2012-12-26
// 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 7.0 and Firefox 2.x
// Author: Alexey Ozerov (alexey at ozerov dot de)
// AJAX & CSV functionalities: Krzysiek Herod (kr81uni at wp dot pl)
// Copyright: GPL (C) 2003-2013

// THIS SCRIPT IS PROVIDED AS IS, WITHOUT ANY WARRANTY OR GUARANTEE OF ANY KIND
// USAGE
// 1. Adjust the database configuration and charset in this file
// 2. Remove 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. Upload bigdump.php and your dump files (.sql, .gz) via FTP to the working directory
// 5. Run the bigdump.php from your browser via URL like http://www.yourdomain.com/dump/bigdump.php
// 6. BigDump can start the next import session automatically if you enable the JavaScript
// 7. Wait for the script to finish, do not close the browser window
// 8. 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
// LAST CHANGES
// *** First ideas about adding plugin interface
// *** Fix // delimiter bug
// *** Minor fix to avoid Undefined variable curfilename notice
// *** Handle empty delimiter setting
// *** New way to determine the upload directory
// *** Set UTF8 as default connection charset
// Database configuration
$db_server = 'localhost';

// Connection charset should be the same as the dump file charset (utf8, latin1, cp1251, koi8r etc.)
// See http://dev.mysql.com/doc/refman/5.0/en/charset-charsets.html for the full list
// Change this if you have problems with non-latin letters
$db_connection_charset = 'utf8';
// OPTIONAL SETTINGS
$filename = ''; // Specify the dump filename to suppress the file selection dialog
$ajax = true; // AJAX mode: import will be done without refreshing the website
$linespersession = 3000; // Lines to be executed per one import session
$delaypersession = 0; // You can specify a sleep time in milliseconds after each session

// CSV related settings (only if you use a CSV dump)

$csv_add_slashes = true; // If your CSV data already have slashes in front of ' and " set it to false
// Allowed comment markers: lines starting with these strings will be ignored by BigDump
$comment[]='#'; // Standard comment lines are dropped by default
$comment[]='-- ';
$comment[]='DELIMITER'; // Ignore DELIMITER switch as it's not a valid SQL statement

// $comment[]='CREATE DATABASE'; // Uncomment this line if your dump contains create database queries in order to ignore them
$comment[]='/*!'; // Or add your own string to leave out other proprietary things
// Pre-queries: SQL queries to be executed at the beginning of each import session
// $pre_query[]='SET foreign_key_checks = 0';
// $pre_query[]='Add additional queries if you want here';
// Default query delimiter: this character at the line end tells Bigdump where a SQL statement ends
// Can be changed by DELIMITER statement in the dump file (normally used when defining procedures/functions)
