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

You can write it most simply like this:

$string = @$array[0];

The @ operator will suppress errors, making $string null if $array is empty.
