一维数组数据

$a = [100,102,104
];

需要按照$a排序的二维数组

$b = [104 => ['id' => '104','qipa250' => '104qipa250'],105 => ['id' => '105','qipa250' => '105qipa250'],102 => ['id' => '102','qipa250' => '102qipa250'],100 => ['id' => '100','qipa250' => '100qipa250'],101 => ['id' => '101','qipa250' => '101qipa250']
];

实现方式：

// 使用键名比较计算数组的交集
$intersect_key = array_intersect_key(array_flip($a), $b);
// 使用后面数组的值替换第一个数组的值
$data = array_replace($intersect_key, $b);

最终返回结果：

array:5 [100 => array:2 ["id" => "100""qipa250" => "100qipa250"]102 => array:2 ["id" => "102""qipa250" => "102qipa250"]104 => array:2 ["id" => "104""qipa250" => "104qipa250"]105 => array:2 ["id" => "105""qipa250" => "105qipa250"]101 => array:2 ["id" => "101""qipa250" => "101qipa250"]
