note 114048 added to reserved.variables.server

A word of caution... If you have some PHP code or file that is included from within a web request via Apache + PHP, as well as from a command line script, be very careful to inspect the keys inside of $_SERVER that you intend to use. The keys and values are different, and in fact, it also matters if you are running as your_user, sudo php from your_user, or from root. For example, I just found out that $_SERVER['PWD'] is not available if you run from the command line via sudo (PHP 5.2x, CentOS, YMMV). To make a test, create a file called server.php with the following content: <?php var_dump($_SERVER); ?> Then from the commandline: your_account/dir #$ php server.php > your_account_server.txt your_account/dir #$ sudo php server.php > your_account_sudo_server.txt your_account/dir #$ sudo bash root/dir #$ php server.php > root_server.txt Now you can diff the output of each of these three files and inspect against what you get when viewing the $_SERVER section of phpinfo() from a web request. You may find the differences to be quite striking, in all, four different ways to run the same PHP file! ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/reserved.variables.server.php Edit -- https://master.php.net/note/edit/114048 Del: integrated -- https://master.php.net/note/delete/114048/integrated Del: useless -- https://master.php.net/note/delete/114048/useless Del: bad code -- https://master.php.net/note/delete/114048/bad+code Del: spam -- https://master.php.net/note/delete/114048/spam Del: non-english -- https://master.php.net/note/delete/114048/non-english Del: in docs -- https://master.php.net/note/delete/114048/in+docs Del: other reasons-- https://master.php.net/note/delete/114048 Reject -- https://master.php.net/note/reject/114048 Search -- https://master.php.net/manage/user-notes.php
