We decided that the name should always be seven digits long and the file would be correspondent  to the line number in the database. For example line seven would link to a file 0000007.txt.

code for the id from MySQL
$mynr = mysql_insert_id();

code for the seven digits
$mynr = sprintf(”%07d”,$mynr);
