Bug description: array_unique works opposed to the manual
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.
