note 30522 added to reserved

I don't see anywhere else in the manual where this is documented, so: the __FILE__ keyword is the filename of the current file, and __LINE__ is the line in the file. Note that this is not the same as using some of the variables, such as $GLOBALS['PHP_SELF'], because for example: bar.php: <?php echo "\n"; echo __FILE__; echo "\n"; echo __LINE__; ?> foo.php: <?php include("bar.php"); echo "\n"; echo __FILE__; echo "\n"; echo __LINE__; ?> executing foo.php gives me this: /var/www/html/bar.php 5 /var/www/html/foo.php 6 Whereas if I used for example $GLOBALS['SCRIPT_FILENAME'] I would see the same filename for both outputs... suppose I change bar.php to be <?php echo "\n"; echo __FILE__; echo $GLOBALS['SCRIPT_FILENAME']; ?> Then executing foo.php will say /var/www/html/bar.php // <-- this line came from bar.php /var/www/html/foo.php // <-- this line came from bar.php /var/www/html/foo.php // <-- this line came from foo.php 6 -- http://www.php.net/manual/en/reserved.php http://master.php.net/manage/user-notes.php?action=edit+30522 http://master.php.net/manage/user-notes.php?action=delete+30522 http://master.php.net/manage/user-notes.php?action=reject+30522
