Write persistent data to a file on server side ----- Original Message ----- From: "Mathias Rockel" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, January 14, 2003 8:12 AM Subject: Re: [PHP] Persistent global data ?
Hi! I'm not sure if that would be a good idea in respect to performance, also AFAIR cookies cannot save objects (can they?), and there are size limitations on cookies, so I probably cannot use them because they could not contain all the data ... and also, if I have the complete file structure saved on the client side its very easy to modify the data, possibly getting access to stuff that is not meant to be seen ... no cookies =). thanks anyway ! mathias rockel ----- Original Message ----- From: "Rick Emery" <[EMAIL PROTECTED]> To: "Mathias Rockel" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Tuesday, January 14, 2003 3:06 PM Subject: Re: [PHP] Persistent global data ? > cookies? > > ----- Original Message ----- > From: "Mathias Rockel" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Tuesday, January 14, 2003 7:33 AM > Subject: [PHP] Persistent global data ? > > > Hi all ! > > I am currently writing some kind of Document/File-Library in a LAMP > environment. > > As the library should be able to handle various file types, and most file > types have to be handled differently internally, I would like to use > Objects/Classes to make the code for the Library iself independent from the > stuff that is individual to the different file types. > > Now I noticed early that when I use Objects in PHP and have to create many > for them each time a script runs it slows the system down considerably.
