PhpLiteAdmin
phpLiteAdmin is an open source tool written in PHP intended to handle the administration of SQLite over the World Wide Web. Its feature set, interface, and overall user experience is comparable to that of phpMyAdmin for MySQL. In the same way that SQLite is a flat file database, phpLiteAdmin is distributed in the form of a single PHP file (currently approx. 200 KiB in size). Its ease of installation, portability, and small size go hand in hand with SQLite.
