dbFacile - A Database API that should have existed from the start
|
||||
Version 0.4.3
|
||||
|
||||
This code is covered by the MIT license http://en.wikipedia.org/wiki/MIT_License
|
||||
|
||||
By Alan Szlosek from http://www.greaterscope.net/projects/dbFacile
|
||||
|
||||
The non-OO version of dbFacile. It's a bit simplistic, but gives you the
|
||||
really useful bits in non-class form.
|
||||
|
||||
Usage
|
||||
1. Connect to MySQL as you normally would ... this code uses an existing connection
|
||||
2. Use dbFacile as you normally would, without the object context
|
||||
3. Oh, and dbFetchAll() is now dbFetchRows()
