关于PHP array_diff（）函数的用法？ [关闭]

When i use array_diff() functions like; $result = array_diff($array1, $array2);

It turns like; Array( [5] => XXXXXX )

But i dont want to show " Array ( "index here" ) ", only XXXXX part. How can i show only XXXXX? Thanks for every comments...

Obtain the first element that is different -or- NULL if there is no difference.

list($result) = array_values(array_diff($array1, $array2)) + [NULL];

You can do:

var_dump($result);

See Demo.

To just out put the value you can do:

foreach($result as $value){
    echo $value;
}
