Re: [PHP] connecting to mysql db
This really doesn't explain me much. I mean the difference between having that code on every page or calling it from an external page doesn't tell me if it is realy necessary to do it all the time. I guess I am looking for more generic explanation of the whole process rather than what you said.

RE: [PHP] connecting to mysql db
No dude. Create a file called whatever.inc that includes the code that you are using to connect to the db. In every php script ,that needs this connection to the db, you simply put: ?php include(whatever.inc); ?

RE: [PHP] connecting to mysql db
Hi Iggy, I mean the difference between having that code on every page or calling it from an external page doesn't tell me if it is realy necessary to do it all the time. Yes, you do have to connect to the database in every script that needs to access it. Usually this is done at the start of the script, along with any calls to session_start() and other global stuff. For convenience and ease of maintenance, however, it makes good sense to write a separate file that does nothing but connect to the database. This separate file then needs to be attached to the running script via include(), at any point before the first call to the database.

RE: [PHP] connecting to mysql db
This is the only way I know and probably the safest. This way you know there is connectivity because it is loaded rigth at the beginning.

Re: [PHP] connecting to mysql db
leaving the connection open creates security questions, and also leaves resources open, what if a user closes his browser window, how do you know to close the connection? if you really want to make it simple, you can edit your php.ini to have the username and password as default in there, but again, this can be a security risk. i'm afraid the best way is to include connection code on every page... -- skate - fatcuban.com Iggy [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] This really doesn't explain me much.
