What are the advantages and disadvantages of using sort() versus usort() for sorting multidimensional arrays in PHP?

When sorting multidimensional arrays in PHP, using the sort() function will only sort the values within each subarray, while usort() allows for custom sorting based on a user-defined comparison function. The advantage of using sort() is its simplicity and ease of use, while the advantage of usort() is the flexibility it offers in defining custom sorting criteria. However, usort() may be slightly more complex to implement compared to sort(). 

// Using sort() to sort multidimensional array by values within subarrays
$array = [
    ['name' => 'Alice', 'age' => 30],
    ['name' => 'Bob', 'age' => 25],
    ['name' => 'Charlie', 'age' => 35],
];

sort($array);

print_r($array);
