The array_diff() function is specifically designed to return the difference between two or more arrays. It looks at each element in the first array and checks if it exists in any of the other arrays. If it doesn't exist in any of them, then it's added to the resulting array. This is different from array_compare(), which is not a built-in PHP function, and array_search() and array_match(), which both look for a specific element within an array.
