//数组转集合,根据排列条件优先级拼接sort字段
$result = collect($testData)->map(function($data){
    $data['sort'] = $data['name'].'_'.$data['time'].'_'.$data['score'];
    return $data;
})->sortBy('sort')->toArray();
//去除数组中sort(可选)
$result = collect($result)->map(function($data){
	unset($data['sort']);
	return $data;
})->toArray();
//重新排序key(可选)
$result = array_value($result);
方式二,链式使用sortBy,后者优先级高
 
 
但这种排序一般不尽人意
 
$result = collect($testData)->sortBy('字段1')->sortBy('字段2');
方式三,php原生函数,此处省

                    方式1 : 数组转集合,根据排列条件优先级拼接sort字段//测试数组$testData = [	[		'name' => '张三',		'score' => '96',		'time' => '2021-12-01',	],	[		'name' => '张三',		'score' => '85',		'time' => '2021-11-01',	],	[		'name' => '李四',		'score' => '91',
