如何根據特定屬性對 PHP 中的物件陣列進行有效排序？

function cmp($a, $b) {
    return strcmp($a->name, $b->name); // Sort by "name" property
}

usort($your_data, "cmp");

usort($your_data, function($a, $b) {
    return strcmp($a->name, $b->name);
});

class ComparisonClass {
    public function cmp($a, $b) {
        return strcmp($a->name, $b->name);
    }
}

$obj = new ComparisonClass();
usort($your_data, array($obj, "cmp"));

usort($your_data, fn($a, $b) => strcmp($a->name, $b->name));

usort($your_data, function($a, $b) {
    return $a->count - $b->count;
});
