Summary: Conflict between $GLOBALS["now"] and $now
Status: Not a bug
Type: Bug

Operating System: All

New Comment:
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.

$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"]) . "\n";
}
?>

Description:
------------
A value is assigned to $GLOBALS["now"], however this is removed when a value is assigned
to $now, as in the example below
Test script:
---------------
$GLOBALS["now"] = time();
print "Year is " . strftime("%Y", $GLOBALS["now"]) . "\n";
$now = new DateTime("now");
print "Year is " . strftime("%Y", $GLOBALS["now"]) . "\n";
Expected result:
----------------
Year is 2020
Year is 2020
Actual result:
--------------
Year is 2020
<br /> <b>Warning</b>: strftime() expects parameter 2 to be int, object given in
<b>[...][...]</b> on line <b>10</b><br /> Year is
