我有一系列物体从数据库返回。 在未经编辑的阵列上打字机:

Array
(
    [0] => stdClass Object
        (
            [nid] => 53162
            [title] => Kroger 'Giving Hope' Standee
            [path] => node/53162
        )

    [1] => stdClass Object
        (
            [nid] => 64185
            [title] => Kroger 'Giving Hope' Stanchion Sign
            [path] => node/64185
        )

    [2] => stdClass Object
        (
            [nid] => 52190
            [title] => Betty Crocker Kroger 'Giving Hope' Shipper
            [path] => node/52190
        )

    [3] => stdClass Object
        (
            [nid] => 53159
            [title] => Frito-Lay Kroger 'Giving Hope' Packaging
            [path] => node/53159
        )

    [4] => stdClass Object
        (
            [nid] => 53164
            [title] => Nabisco Kroger 'Giving Hope' Violator
            [path] => node/53164
        )

    [5] => stdClass Object
        (
            [nid] => 52607
            [title] => Doritos Kroger 'Giving Hope' Packaging
            [path] => node/52607
        )

    [6] => stdClass Object
        (
            [nid] => 52720
            [title] => Kroger Big K Cola 'Giving Hope' Packaging
            [path] => node/52720
        )

    [7] => stdClass Object
        (
            [nid] => 52729
            [title] => Windex Kroger 'Giving Hope' Packaging
            [path] => node/52729
        )

    [8] => stdClass Object
        (
            [nid] => 52731
            [title] => Ziploc Kroger 'Giving Hope' Packaging
            [path] => node/52731
        )

    [9] => stdClass Object
        (
            [nid] => 53157
            [title] => Stacy's Kroger 'Giving Hope' Cut Cases
            [path] => node/53157
        )

)

I want to sort the array by the nid property, so I used a custom usort function (found here.)

function my_search_sort($a, $b) {
  strcmp($a->nid, $b->nid);
}

我这样说:

usort($docs,  my_search_sort );

之后还有另一台打印机。 结果是:

Array
(
    [0] => stdClass Object
        (
            [nid] => 52720
            [title] => Kroger Big K Cola 'Giving Hope' Packaging
            [path] => node/52720
        )

    [1] => stdClass Object
        (
            [nid] => 52729
            [title] => Windex Kroger 'Giving Hope' Packaging
            [path] => node/52729
        )

    [2] => stdClass Object
        (
            [nid] => 52731
            [title] => Ziploc Kroger 'Giving Hope' Packaging
            [path] => node/52731
        )

    [3] => stdClass Object
        (
            [nid] => 53157
            [title] => Stacy's Kroger 'Giving Hope' Cut Cases
            [path] => node/53157
        )

    [4] => stdClass Object
        (
            [nid] => 52607
            [title] => Doritos Kroger 'Giving Hope' Packaging
            [path] => node/52607
        )

    [5] => stdClass Object
        (
            [nid] => 53164
            [title] => Nabisco Kroger 'Giving Hope' Violator
            [path] => node/53164
        )

    [6] => stdClass Object
        (
            [nid] => 64185
            [title] => Kroger 'Giving Hope' Stanchion Sign
            [path] => node/64185
        )

    [7] => stdClass Object
        (
            [nid] => 52190
            [title] => Betty Crocker Kroger 'Giving Hope' Shipper
            [path] => node/52190
        )

    [8] => stdClass Object
        (
            [nid] => 53159
            [title] => Frito-Lay Kroger 'Giving Hope' Packaging
            [path] => node/53159
        )

    [9] => stdClass Object
        (
            [nid] => 53162
            [title] => Kroger 'Giving Hope' Standee
            [path] => node/53162
        )

)

它显然做了thing,但它没有按照 n令分类。 我需要做些什么才能做到这一点?
