note 78151 added to ref.session

Another gotcha to add to this list is that using a relative session.save_path is a VERY BAD idea. You can just about pull it off, if you're very careful, but note two related points: 1) The path is taken relative to the directory of the ORIGINALLY executed script, so unless all pages are run from the same directory, you'll have to set the directory separately in each individual subfolder 2) If you call certain functions, such as session_regenerate_id(), PHP will try to take the session directory relative to the exectuable, or something like that, creating an error IN the executable. This provides slightly cryptic error messages, like this: Warning: Unknown: open(relative_path\ilti9oq3j9ks0jvih1fmiq4sv1.session, O_RDWR) failed: No such file or directory (2) in Unknown on line 0 Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (relative_path) in Unknown on line 0 ... so don't even bother. Just use <?php ini_set("session.save_path",dirname(__FILE__)."/relative_path"); ?> (or equivalent) in a file which you know is always in the same place relative to the file. {PHP version 5.1.6} ---- Server IP: 194.145.210.4 Probable Submitter: 84.43.70.129 ---- Manual Page -- http://www.php.net/manual/en/ref.session.php Edit -- https://master.php.net/note/edit/78151 Del: integrated -- https://master.php.net/note/delete/78151/integrated Del: useless -- https://master.php.net/note/delete/78151/useless Del: bad code -- https://master.php.net/note/delete/78151/bad+code Del: spam -- https://master.php.net/note/delete/78151/spam Del: non-english -- https://master.php.net/note/delete/78151/non-english Del: in docs -- https://master.php.net/note/delete/78151/in+docs Del: other reasons-- https://master.php.net/note/delete/78151 Reject -- https://master.php.net/note/reject/78151 Search -- https://master.php.net/manage/user-notes.php
