Are there any specific advantages of using usort() over custom sorting methods in PHP for complex data structures?

When dealing with complex data structures in PHP, using the built-in usort() function can offer several advantages over implementing custom sorting methods. usort() allows for a more concise and readable way to sort arrays based on custom criteria, without the need to write complex sorting algorithms. It also provides better performance as it is a built-in function optimized for sorting arrays efficiently. 

// Example of using usort() to sort a complex data structure
$data = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 35]
];

usort($data, function($a, $b) {
    return $a['age'] <=> $b['age']; // Sort by age in ascending order
});

print_r($data);
