Remove duplicates from array

Question

I have two arrays, like this:

$array1 = array(
'ADAIR',
'ADAM',
'ADAMINA',
'ADDISON',
'ADDY',
'ADELLE',
'ADEN',
'ADOLPH',
'ADRIANNA'
);

$array2 = array(
'ADAIR',
'ADAMINA',
'ADRIANNA'
);

How do I make a third array, without duplicates? We should take first array and remove from it duplicates from second array.

Answer 1

Use Array-diff

$array3=array_diff($array1,$array2);

Returns an array containing all the entries from array1 that are not present in any of the other arrays.
