well you gotta make sure that the record that you are deleting is not being used by another program, you will have to look at the other program and determine when they run, it will be difficult to automate that.
to physically delete a record you have to find the id of the record ( i presume that each record is stored with a primary (unique) key, and secondly each record has its own row. to delete it you loop through the rows and every row check if the key to be deleted is the key of that row, if so then delete the row, you will need to use some string functions mid, left right, instr etc... see the documentation for that. I havent given you any code but thats how you would do it in theory just use the manual to develop what ive said into php code. good luck -----Original Message----- From: Gamze Basaran [mailto:[EMAIL PROTECTED] Sent: Thursday, January 22, 2004 10:46 AM To: [EMAIL PROTECTED] Subject: [PHP-DB] how can I delete a record from txt file Hi; I take users from Active Directory with ldap functions and put them in a list menu.
