Description:
------------
When the name of a built in array is stored inside of an object
attribute, its contents can't be access from the 'variable variable'
without the use of eval.
So, print_r(${$this->array}) and print_r($$this->array) don't work, but
eval("print_r(\${$this->array});") does.
When trying the same thing on a "regular" variable variable, it works
as expected.
Reproduce code:
---------------
<?php
$built_in_array = '_SERVER';
class klass {
function klass($array = '_SERVER') {
$this->array = $array;
}
function printit() {
print_r(${$this->array});
#eval ("print_r(\${$this->array});");
}
}
print_r(${$built_in_array});
$k = new klass();
$k->printit();
?>
Expected result:
----------------
Array
(
[HZ] => 100
[TERM] => rxvt
[SHELL] => /bin/bash
[WINDOWID] => 31457282
...etc...
Array
(
[HZ] => 100
[TERM] => rxvt
[SHELL] => /bin/bash
[WINDOWID] => 31457282
...etc...
Actual result:
--------------
Array
(
[HZ] => 100
[TERM] => rxvt
[SHELL] => /bin/bash
[WINDOWID] => 31457282
...etc...
