fork of php mysql[i][nd] extension for script filehash based db auth

Aloha, I'd like to see a fork of the mysql extensions and perhaps other databases (I'm actually a little partial to postgres), that allows mysql to authenticate php scripts based on their file contents, or hash, or inode modification time. Basically during mysql_[p]connect() calls, 1. checks if feature is enabled, 2. gathers additional data script path and name hash, script file contents hash (only computed if mtime changed), script file inode mtime, desired database name, 3. then uses this data as a key to a flat file berkeley db in /etc/php5/ 4. where it could be returned a data record containing mysql hostname, real database name, real username, real password, 5. and then transparently continues it's connection to mysql, 6. and upon success returns the connection to the php script, which never knew the difference. I'm almost done coding this idea into the old mysql extension for a proof of concept and assuming it received positive feedback would enjoy coding it into mysqli or mysqlnd, or others. I also coded up a little helper program for managing the bdb table, to create, add, update, and remove records from the /etc/php5/mysql_auth.db database, that the extension consults upon page requests. I'm doing this for a school project, for extra credit in my Software Engineering class. It'd be great if this idea really worked, and if there was not some huge hole in my thinking on this subject. In any case I welcome opinions on it. I'm particularly interested in knowing what fields would be useful in the key and data. thank you. /juan -- "only during tornadoes do apples fall far from the tree."
