It is extremely counter-intuitive to have parameters named after
superglobal variables.
<?php
/**
* This function looks like it does nothing.
*/
function EmptyFunction($_POST)
{
}
// Build $_GET
$_GET['Name'] = 'Richard';
print_r($_GET);
print_r($_POST);
EmptyFunction($_GET);
print_r($_GET);
print_r($_POST);
?>
Rather than doing nothing, any parameter passed to it will be assigned
to the super global $_POST array.
There is no "pass be reference" &$_POST which would be one way to
alter a variable that exists outside of the scope of the function.
If your intention _IS_ to assign to the $_POST super-global, then just
assign it. Don't pass it.
Using any super global as a parameter is almost always NOT going to
have the intent required.
Things get really quite odd if the parameter is $GLOBALS.
<?php
function EmptyFunction($GLOBALS)
{
}
// Build $_GET
$_GET['Name'] = 'Richard';
$Age = 43;
EmptyFunction($_GET);
var_dump($GLOBALS);
echo $Name, $Age;
?>
The output here is ...
array(1) {
["Name"]=>
string(7) "Richard"
}
Notice: Undefined variable: Name in Z:\testsg.php on line 12
43
So, the link between the global variables and $GLOBALS super global is
now broken.
$Name isn't in global scope and $Age isn't in $GLOBALS.
