PHP Version: 4.0.6
New Comment:
I forgot to mention that there may be something wrong with
array_unique itself. There are three values of 3 considered equal in the example
above:
2 => "3"(string), 4 => 3(int), 5 => "3" (string)
[manual]
" Two elements are considered equal if and only if (string)
" $elem1 === (string) $elem2. In words: when the string
" representation is the same."
Why does array_unique use the index 4 in this case?
(It's neither the first nor the latest key of value 3)

The manual (recent version from cvs) states that :
" array_unique() will keep the first key encountered for every value, and ignore all
following keys. "
I've tested the two examples in this page and I've found
this statement is not true.
<?php
$input = array (4,"4","3",4,3,"3");
$result = array_unique ($input);
var_dump($result);
?>
output: /* PHP 4.0.6 Win'98 PWS */
array(2) {
[3]=>
int(4)
[4]=>
int(3)
}
but the manual says it should print:
array(2) {
[0]=>
int(4)
[1]=>
string(1) "3"
}
As you can recognize the latest keys are preserved
for both value 4 and 3.
