In reference/array/functions/array-unique.xml file there's an example:
$input = array (4,"4","3",4,3,"3");
$result = array_unique ($input);
var_dump($result);
The printout of the program above will be (PHP 4.0.6):
array(2) {
[3]=>
int(4)
[4]=>
int(3)
}
But in my Linux system, both PHP 4.0.6 and PHP 4.3.0-dev print the following
result:
array(2) {
[0]=>
int(4)
[2]=>
string(1) "3"
}
And in PHP 4.2.3-dev under Windows it print out:
array(2) {
[1]=>
string(1) "4"
[5]=>
string(1) "3"
}
This really confused me. What's going on here? Thanks in advance.
