Is there a recommended approach or method for merging arrays in PHP that maintains the integrity of the data and prevents index conflicts?
When merging arrays in PHP, one recommended approach to maintain the integrity of the data and prevent index conflicts is to use the `array_merge` function. This function combines the values of two or more arrays into a single array, with duplicate keys overwritten with the values from the latter arrays. This ensures that the resulting array contains all unique keys and values without losing any data.
$array1 = ['a' => 1, 'b' => 2];
$array2 = ['b' => 3, 'c' => 4];
$mergedArray = array_merge($array1, $array2);
print_r($mergedArray);
