#38422 [NEW]: session.use_trans_sid not changeable by ini_set

From: strube at physik3 dot gwdg dot de Operating system: Solaris 9 (SPARC) PHP version: 4.4.3 PHP Bug Type: Session related Bug description: session.use_trans_sid not changeable by ini_set Description: ------------ In PHP 4.4.2 and 4.4.3 (cannot test earlier ones any more), the option session.use_trans_sid cannot be changed by function ini_set, but can be changed using php.ini or the command-line option -d. Also ini_set always returns 0 as the old value for session.use_trans_sid, even if it was set to 1. (BTW, this causes test ext/session/tests/bug36459.phpt to fail -- not because of bug 36459, of course.) The bug persists even on a second call to ini_set (unlike bug #30422).
