I have 2 arrays I want to get the values that are not the same but for some reason this is not working:
$newArray = array_unique(array_merge($array1, $array2)
var_dump(array1) = array(3) { [0]=> string(17) "verbal aggression" [1]=> string(19) "physical aggression" [2]=> string(3) "vol" }
var_dump(array2) = array(2) { [0]=> string(17) "verbal aggression" [1]=> string(19) "physical aggression" }
So I suspect $newArray to be:
array(1) { [0]=> string(3) "vol"" }
array_diff — Computes the difference of arrays
$array1 = array("verbal aggression", "physical aggression", "vol");
$array2 = array("verbal aggression", "physical aggression");
$result=array_diff($array1,$array2);
print_r($result);
Output :
Array
(
[2] => vol
)
If you want the difference between two arrays you can use array_diff as suggested by @Sunil. But that finds only the elements that are in $array1 but not in $array2.
If you want to find differences use the function below. This will also find elements that are in $array2 but not in $array1
function differences($array1, $array2){
return array_merge(array_diff($array1,$array2),array_diff($array2,$array1));
}
