權(quán)限列表的循環(huán)

如題我有一個(gè)查詢(xún)會(huì)查出當(dāng)前用戶(hù)所有的權(quán)限

$authList = [
    ['id' => 1, 'pid' => 0, 'title' => 'project'],
    ['id' => 2, 'pid' => 0, 'title' => 'customer'],
    ['id' => 3, 'pid' => 1, 'title' => 'select'],
    ['id' => 4, 'pid' => 1, 'title' => 'delete'],
    ['id' => 5, 'pid' => 2, 'title' => 'select'],
    ['id' => 6, 'pid' => 2, 'title' => 'delete'],
    ['id' => 7, 'pid' => 6, 'title' => 'logic delete']
];

我想重新組織這個(gè)數(shù)組使它根據(jù)pid變成樹(shù)形結(jié)構(gòu)，就像這樣

$result = [
    [
        'id' => 1,
        'pid' => 0,
        'title' => 'project',
        'children' => [
            [
                'id' => 3,
                'pid' => 1,
                'title' => 'select'
            ],
            [
                'id' => 4,
                'pid' => 1,
                'title' => 'delete'
            ],
        ]
    ],
    [
        [
            'id' => 2,
            'pid' => 0,
            'title' => 'customer',
            'children' => [
                [
                    'id' => 5,
                    'pid' => 2,
                    'title' => 'select'
                ],
                [
                    'id' => 6,
                    'pid' => 2,
                    'title' => 'delete',
                    'children' => [
                        [
                            'id' => 7,
                            'pid' => 6,
                            'title' => 'logic delete'
                            ]
                    ],
                ]
            ],
        ],
    ],

];

請(qǐng)問(wèn)大家有沒(méi)有什么要率高的算法？
