Couldn't see this beeing brought up, so I write it here
so all can be clear:
<?php
define('test', 8);
$foo[8] = "debug 1";
$foo['test'] = "debug 2";
print $foo[test]; // "debug 1"
print $foo['test']; // "debug 2"
?>
What happens when we use a string variable as key?
<?php
$str = "test";
print $foo[$str];
?>
One (wrong) way of reasoning:
=> $str outputs just test (without quotes)
=> $foo[$str] should then translate to $foo[test]
=> $foo[test] whould translate to $foo[8] (because test is a defined constant)
=> output should then be "debug 1"
This is wrong! ..but I'm sure I'm not the only one who thought about this.. ;)
Both $foo[$str] and $foo["$str"] outputs "debug 2"
