RE: [PHP-DB] HEAP table
Thanks, Daevid I'll probably use something with session variables. However, what I wish is that there was some kind of application-wide variables, as can be set in ColdFusion, that could track this. I cannot find any means to create such variables in PHP. Anyone got any ideas on those lines? Cheers Terry --Original Message- Or instead of creating a table and tying up one more mysql thread, just save the timestamp in a file. This could be as simple as that, you could use XML, you could use INI parser, you could use any number of things. Also, if the HEAP is created per session, then just store that timestamp in a session variable and avoid any disk i/o that way. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 08, 2003 9:24 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: [PHP-DB] HEAP table Create a create_date table with one record, one or two fields, and put the last refreshed time/date in it.

RE: [PHP-DB] HEAP table
Good idea, Ben. I'll remember that when I can afford to have hosting on a non-shared server :-) , but can't use it at the moment. Cheers Terry --Original Message- You could have a php file set variables or an array called $GLOBAL[some_global_variable], go into the php.ini and set auto_prepend to this file. So EVERY php script that is called will first load this file.
