XPATH - get single value returned instead of array php

Question

I am using Xpath in PHP - I know that my query will return either 0 or 1 results.

If 1 result is returned I do not want it as an array - which is what is returned ri

Answer 1

probably

if ($array[0]){
    $string = $array[0];
}

?

if $array[0] is an array, you can rename string to new_array

if ($array[0]){
    $new_array  = $array[0];
}
