Re: Oh what a fool I am (Oracle/PHP connection)

Hi to all Thanks to you too Andy. Firstly I wanna say that I agree with you. Php manual page forced us to make this fault and wanna ask a question about how to keep persistent connection on php pages using oracle ( ocilogon lets people to access their rights , informations, pages while skipping other pages or log off the user without logging of by ocilogoff) . How to keep an oracle log when passing to another page.? (most stable, secure , easiest way) php oci8 functions do this by default , should we use session functions or cookies ??? and also I am from Turkiye (Turkey) ----- Original Message ----- From: "Andy Hoffman" <andy.hoffman@bms.com> To: "Vince LaMonica" <Vince.LaMonica@quest.com>; "Mustafa SARI" <msari@fatih.edu.tr>; <jasendorf@lcounty.com> Cc: <php-windows@lists.php.net> Sent: Friday, November 03, 2000 5:24 PM Subject: Oh what a fool I am (Oracle/PHP connection) > Folks, > > A bright new light has dawned in the "figuring out how to > use oci8 & php".
