note 90007 added to function.session-start

If you want to check if a session has already been activated, you can check $_COOKIE["PHPSESSID"] for a value before reactivating that session. Example code: == login.php == <?php session_start(); $_SESSION["data"] = "you have an active session!"; echo "<a href=\"page.php\">go</a>"; ?> == page.php == <?php if(isset($_COOKIE["PHPSESSID"])) { session_start(); echo $_SESSION["data"]; } else { echo "no cookies required!"; } ?> This can prevent forcing a cookie on someone (very annoying in lynx) that doesnt intend to login on your site. ---- Server IP: 209.41.74.194 Probable Submitter: 68.230.177.153 ---- Manual Page -- http://www.php.net/manual/en/function.session-start.php Edit -- https://master.php.net/note/edit/90007 Del: integrated -- https://master.php.net/note/delete/90007/integrated Del: useless -- https://master.php.net/note/delete/90007/useless Del: bad code -- https://master.php.net/note/delete/90007/bad+code Del: spam -- https://master.php.net/note/delete/90007/spam Del: non-english -- https://master.php.net/note/delete/90007/non-english Del: in docs -- https://master.php.net/note/delete/90007/in+docs Del: other reasons-- https://master.php.net/note/delete/90007 Reject -- https://master.php.net/note/reject/90007 Search -- https://master.php.net/manage/user-notes.php
