PHP Bug Type: Scripting Engine problem
Bug description: Accessing superglobal arrays in functions via variable variable names
Please try the following script:
<?php
function foo() {
echo $_SERVER;
}
foo();
?>
This script returns "Array". This is the expected behavior.
Now, try this one:
<?php
function foo() {
$bar = '_SERVER';
echo $$bar;
}
foo();
?>
This time, an error is returned:
Notice: Undefined variable: _SERVER on line 4
This is nonsense, of course: As we see in the example above, the variable
should be defined!
