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

I understand what you want. You want to check every data of the array if all of it is empty or at least 1 is not empty

Empty array

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

Not an Empty array

Array ( [Tags] => SimpleXMLElement Object ( [0] =>,[1] => "s" ) )

---

I hope I am right. You can use this function to check every data of an array if at least 1 of them has a value.

/*
 return true if the array is not empty
 return false if it is empty
*/
function is_array_empty($arr){
  if(is_array($arr)){     
      foreach($arr $key => $value){
          if(!empty($value) || $value != NULL || $value != ""){
              return true;
              break;//stop the process we have seen that at least 1 of the array has value so its not empty
          }
      }
      return false;
  }
}

if(is_array_empty($result['Tags'])){
    //array is not empty
}else{
    //array is empty
}

Hope that helps.
