TheJoey Posted October 3, 2009 Share Posted October 3, 2009 hi im currenlty trying to read from a file that saves all my session data into a txt file. Only problem is when i read from it i only get Resource id #3 <?php $sessionfile = fopen("sessionfile.txt", "w"); fputs($sessionfile, session_encode( ) ); fclose($sessionfile) ?> <?php session_start(); ?> <?php $sessionfile = fopen("sessionfile.txt", "r"); session_decode(fputs($sessionfile, 4096) ); fclose($sessionfile); ?> <html> <body> <?php echo $sessionfile; ?> </body> </html> Link to comment https://forums.phpfreaks.com/topic/176352-saving-data-into-a-session/ Share on other sites More sharing options...
Zyx Posted October 3, 2009 Share Posted October 3, 2009 Take a look at this: http://docs.php.net/manual/en/language.types.resource.php Basically, you are trying to display a file handle that is stored in $sessionfile. It is only used to identify the physical file on the hard disk after it has been opened and nothing more. Anyway, your code contains more mistakes and misunderstandings of the basic PHP concepts. Take a look - you are using fputs() (writing) to read the file, whereas you should use fgets() instead. However, this is not a good function, too. You read only 4096 bytes and what if the content is longer? It will be cut off. You must either read it in a loop and then pass to the next function or use file_get_contents(). The next mistake: session_decode() does not return any decoded values, but saves them into a session. So, in order to display them, you need to use $_SESSION variable.

TheJoey Posted October 3, 2009 Author Share Posted October 3, 2009 Trying to correct my code the first problem i ran into was Warning: file_get_contents() expects parameter 1 to be string, when replacing fputs. The other thing i dont understand is, When you say use $_SESSION? all i know is that when i do the saving part, it seems to work well and encrypts the information i need. it just displaying it that im having trouble with Link to comment https://forums.phpfreaks.com/topic/176352-saving-data-into-a-session/#findComment-929525 Share on other sites More sharing options...
Zyx Posted October 3, 2009 Share Posted October 3, 2009 Once again, just take a look at the manual (it really does not hurt ) and you'll know everything: http://docs.php.net/file_get_contents file_get_contents() expects string, because you put there the file name to read, not the file handle created by fopen(). Displaying -> when decoded, the session data are saved back to the $_SESSION array. If you need to read them or display, you have to access it, i.e.: echo $_SESSION['my_decoded_variable']; var_dump($_SESSION); // for debugging Link to comment https://forums.phpfreaks.com/topic/176352-saving-data-into-a-session/#findComment-929589 Share on other sites More sharing options...
