The variable names are the keys of the array. > The variable defined outside of a function or class is simply > a local variable outside of a function or class nonsense - you had 15 years time to learn some basics like https://www.php.net/manual/en/language.variables.scope.php frankly if you write $GLOBALÖS['foo'] or global $foo withina function is the same and when you write $GLOBALS in the global scope you waste performance for no good reason (useless ) php > echo $GLOBALS['x']; filename: php shell code function name: (null) number of ops: 4 compiled vars: none line #* E I O op fetch ext return operands ------------------------------------------------------------------------------------- 1 0 E > FETCH_R global ~0 'GLOBALS' 1 FETCH_DIM_R ~1 ~0, 'x' 2 ECHO ~1 2 3 > RETURN null branch: # 0; line: 1- 2; sop: 0; eop: 3; out0: -2 path #1: 0, php > echo $x; filename: php shell code function name: (null) number of ops: 2 compiled vars: !0 = $x line #* E I O op fetch ext return operands ------------------------------------------------------------------------------------- 1 0 E > ECHO !0 2 1 > RETURN null branch: # 0; line: 1- 2; sop: 0; eop: 1; out0: -2 path #1: 0, php > ------------------------------------------------------------------------ [2020-05-28 23:49:12] requinix@php.net > I would also like to propose that these should be treated as separate.

I have a counter-proposal for you: Don't use $GLOBALS. ------------------------------------------------------------------------ [2020-05-28 23:22:22] murray at focus-computing dot com dot au I've been programming with PHP for about 15 years now. I've always assumed the $GLOBALS was a reference to an array of variables unrelated to the variables defined outside of functions and classes. I would also like to propose that these should be treated as separate. The variable defined outside of a function or class is simply a local variable outside of a function or class. ------------------------------------------------------------------------ [2020-05-28 13:45:07] bugreports at gmail dot com $GLOBALS["now"] and $now are the same variable in the global scope and there is no point to write $GLOBALS at all outside functions <?php $GLOBALS["now"] = time(); print "Year is " . strftime("%Y", $GLOBALS["now"]) . "\n"; $now = new DateTime("now"); print "Year is " . strftime("%Y", $GLOBALS["now"]) . "\n"; ?> versus <?php test(); function test() { $GLOBALS["now"] = time(); print "Year is " . strftime("%Y", $GLOBALS["now"]) . "\n"; $now = new DateTime("now"); print "Year is " . strftime("%Y", $GLOBALS["now"]) .
