Check If array is null or not in php

Question

I have an array like below which is generated by parsing a xml url.

The array is

Array
  (
 [Tags] => SimpleXMLElement Object
    (
        [0] =         


        

Answer 1

This checks if the array is empty

if (!empty($result) {
    // do stuf if array is not empty
} else {
    // do stuf if array is empty
}

This checks if the array is null or not

if (is_null($result) {
   // do stuf if array is null
} else {
   // do stuf if array is not null
}
