Can't concatenate 2 arrays in PHP

Question

I\'ve recently learned how to join 2 arrays using the + operator in PHP.

But consider this code...

$array = array(\'Item 1\');

$array += array(\'Ite         


        

Answer 1

It is indeed a key conflict. When concatenating arrays, duplicate keys are not overwritten.

Instead you must use array_merge()

$array = array_merge(array('Item 1'), array('Item 2'));
