A simple script to copy the filenames of a directory into a database table


Directories filenames to database ver. 1.00

released: 2006-07-28
This script is an example how to import all filenames of a single directory into a database table. Extra features are: the last modification date is saved in the database too; all filenames that are not imported to the database are stored in an error array. The script is very easy to use: just place the script into the folder where you want to copy the files and modify the database connection string and then run the script via the browser. The script is working on windows/linux, PHP 4 and MySQL 3.23 (or higher)
