PHP函数重新排序数组

Question

以下是来自paypal.com的所有外部JS文件的示例数组:

Array
(
    [src] => Array
        (
            [1] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/lib/min/global.js
            [2] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/tns/mid.js
            [8] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/opinionlab/oo_engine.js
            [11] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/iconix.js
            [12] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/pageBlockingUnsafeBrowsers.js
            [13] => https://www.paypalobjects.com/js/tns/min/bid.js
            [15] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/pp_naturalsearch.js
            [17] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/site_catalyst/pp_jscode_080706.js
        )

    [size] => Array
        (
            [1] => 0.273
            [2] => 0.266
            [8] => 0.279
            [11] => 0.265
            [12] => 0.285
            [13] => 0.248
            [15] => 0.275
            [17] => 0.289
        )

)

是否有PHP的内置函数,或者可以将此数组重新排序为此的自定义(也没有大的性能影响):

Array
(
    [src] => Array
        (
            [1] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/lib/min/global.js
            [2] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/tns/mid.js
            [3] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/opinionlab/oo_engine.js
            [4] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/iconix.js
            [5] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/pageBlockingUnsafeBrowsers.js
            [6] => https://www.paypalobjects.com/js/tns/min/bid.js
            [7] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/pp_naturalsearch.js
            [8] => https://www.paypalobjects.com/WEBSCR-590-20090814-1/js/site_catalyst/pp_jscode_080706.js
        )

    [size] => Array
        (
            [1] => 0.273
            [2] => 0.266
            [3] => 0.279
            [4] => 0.265
            [5] => 0.285
            [6] => 0.248
            [7] => 0.275
            [8] => 0.289
        )

)

Answer 1

这个功能应该可以工作,这很简单.

function reindex_array($src) {
    $dest = array();

    foreach ($array as $key => $value) {
        if (is_array($value)) {
           foreach ($value as $dest_val) {
               $dest[$key][] = $dest_val;
           }
        }
    }

    return $dest;
}

使用Henrik的答案中建议的array_values()

function reindex_array($src) {
    $dest = array();

    foreach ($array as $key => $value) {
        if (is_array($value)) {
           $dest[$key] = array_values($value);
        }
    }

    return $dest;
}

这将使数组索引从0开始.如果您想要基于1的索引,那么使用:

function reindex_array($src) {
    $dest = array();

    foreach ($array as $key => $value) {
        if (is_array($value)) {
           $count = 1;

           foreach ($value as $dest_val) {
               $dest[$key][$count] = $dest_val;
               $count++;
           }
        }
    }

    return $dest;
}

编辑:我没有注意到数组首先嵌套,因此以下是不够的.由于伊姆兰已经纳入了我的建议,我将不再进一步编辑.

检查array_values()函数,它几乎完全符合您的需要.

与你想要的输出的唯一区别在于它从零开始重新索引 - 如果你真的需要索引从一开始,你可以先array_shift()在虚拟条目中,然后在array_unshift()它之后.
