about PHP array_diff( ) functions usage? [closed]

Question

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...

What if the difference will be more than one element? What will be XXXXX in that case? array_diff returns an array containing all the entries from array1 that are not present in any of the other arrays. — Valera Leontyev, Dec 13 '12 at 20:21

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;
}

it shows only one difference. For example: eval.in/4599 – ademcu Dec 13 '12 at 20:38

Try this eval.in/4804 – SeanWM Dec 17 '12 at 0:29
