RE: [PHP] Session troubles

This was problem that I had: the function write was not been called by PHP sessions functions when a script finish or when I change the variable contents. Searching on PHP.net I saw this solution there: add a call to function "session_write_close()" at the end of the php code. This should be another problem with Sessions functions... but I need to test this with PHP 4.1... Thanks, _________________________________ Ricardo J. A.
