What is the difference between using array_merge and array_merge_recursive in PHP?

The main difference between using array_merge and array_merge_recursive in PHP is how they handle merging multidimensional arrays. - array_merge will simply overwrite any duplicate keys with the values from the second array, while array_merge_recursive will recursively merge arrays with the same keys, creating a multidimensional array if necessary. To merge arrays using array_merge_recursive, you can use the following PHP code snippet: 

$array1 = ['a' => ['b' => 'c']];
$array2 = ['a' => ['d' => 'e']];

$result = array_merge_recursive($array1, $array2);

print_r($result);
