Ha! Stupido! I had cut'n'pasted and somehow had a trailing space on the ini entry name!
But, it works a treat. Is this worth mentioning in the dox? I have karma there, but I don't want to add just because I can. On 15/03/07, Richard Quadling <[EMAIL PROTECTED]> wrote:
Hmm. Good idea! I think I also have to turn off session.use_only_cookies. I just tried this, but within the framework the ini_set return false (when the value is currently "1") and the setting was not altered and I've yet to work out why. In a simple test this works fine. <?php for($i = 0 ; $i < 246; ++$i) // 245 counts are OK, 246 are not. { session_start(); $_SESSION['Count'] = $i; session_write_close(); // ini_set("session.use_cookies", 0); // Removing the comment here and upping the count above worked fine. } var_dump($_SESSION); ?> On 15/03/07, Stefan Esser <[EMAIL PROTECTED]> wrote: > Hello Richard, > > your problem is a bug in the session extension. > > My suggested but not tested workaround is that you simply call > > ini_set("session.use_cookies", 0); > > after the first time you call session_write_close().
