If we want to make an array values only comparison we need to make a sort of each array in order to
reset keys and sort all values in the same order.
Here is an example:
$a = array (0 => "apple", 1 => "banana");
$b = array (0 => "banana", 1 => "apple");
var_dump($a,$b);
var_dump($a==$b);
var_dump($a===$b);
sort($a);
sort($b);
var_dump($a,$b);
var_dump($a==$b);
var_dump($a===$b);
// Output
array(2) {
[0]=> string(5) "apple"
[1]=> string(6) "banana"
}
array(2) {
[0]=> string(6) "banana"
[1]=> string(5) "apple"
}
bool(false)
bool(false)
array(2) {
[0]=> string(5) "apple"
[1]=> string(6) "banana"
}
array(2) {
[0]=> string(5) "apple"
[1]=> string(6) "banana"
}
bool(true)
bool(true)
