You're not to fault, and the point about Java collections Vs array()

Oh really? From http://zestyping.livejournal.com/124503.html
% cat equality.php
<?php
$a = 0;
$b = "eggs";
$c = "spam";
print ($a == $b) ? "a == b\n" : "a != b\n";
print ($b == $c) ? "b == c\n" : "b != c\n";
print ($a == $c) ? "a == c\n" : "a != c\n";
print ($a == $d) ? "a == d\n" : "a != d\n";
print ($b == $d) ? "b == d\n" : "b != d\n";
print ($c == $d) ? "c == d\n" : "c != d\n";
?>
% php equality.php
a == b
b != c
a == c
a == d
b != d
c != d
(Of course, starting in version 5, Java began to mess up simple
Aristotelian logic too, but not quite this badly.)
ah, no, these answers are exactly right, given that $a is an integer, $b
and $c are strings, and $d is unset. $b and $c when converted to
integers for the purpose of comparison in #1 and #3 turn into 0 (zero)
so the comparisons are true. #2 compares two different strings and so is
false. #4 compares 0 to the integer of unset and so is true. #5 and #6
compare strings to the string of unset and so are false.
