note 82583 added to reserved.variables

I wanted to know the current file name; and was breaking my head to figure out why I'm getting a NULL for both $PHP_SELF and $_SESSION["PHP_SELF"] and even for $_SESSION["SCRIPT_NAME"]. tried with 2 UNIX servers with no luck. But when I used $_ENV["SCRIPT_NAME"] it worked !! so here's a little snippet to find out what works. echo "Current location= ".$PHP_SELF."<br>"; echo "Current location= ".$_SESSION["SCRIPT_NAME"]."<br>"; echo "Current location= ".$_SESSION["PHP_SELF"]."<br>"; echo "Current location= ".$_ENV["SCRIPT_NAME"]."<br>"; ---- Server IP: 69.147.83.197 Probable Submitter: 123.231.21.239 ---- Manual Page -- http://www.php.net/manual/en/reserved.variables.php Edit -- https://master.php.net/note/edit/82583 Del: integrated -- https://master.php.net/note/delete/82583/integrated Del: useless -- https://master.php.net/note/delete/82583/useless Del: bad code -- https://master.php.net/note/delete/82583/bad+code Del: spam -- https://master.php.net/note/delete/82583/spam Del: non-english -- https://master.php.net/note/delete/82583/non-english Del: in docs -- https://master.php.net/note/delete/82583/in+docs Del: other reasons-- https://master.php.net/note/delete/82583 Reject -- https://master.php.net/note/reject/82583 Search -- https://master.php.net/manage/user-notes.php
