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'));

Answer 2

Use array_merge()
See the documentation here:
http://php.net/manual/en/function.array-merge.php

Merges the elements of one or more arrays together so that the values of one are appended to the end of the previous one. It returns the resulting array.

Answer 3

This works for non-associative arrays:

while(($item = array_shift($array2)) !== null && array_push($array1, $item));

Answer 4

Try saying

$array[] = array('Item 2'); 

Although it looks like you're trying to add an array into an array, thus $array[][] but that's not what your title suggests.
