好吧,我已经在stackoverflow中得到了这个问题,但遗憾的是它是在javascript中 - Javascript - 基于另一个数组的排序数组

我希望它在PHP中

$data = array(
   "item1"=>"1",
   "item2"=>"3",
   "item3"=>"5",
   "item4"=>"2",
   "item5"=>"4"
);

匹配此数组的排列:

sortingArr = array("5","4","3","2","1");

和我正在寻找的输出:

$data = array(
    "item3"=>"5",
    "item5"=>"4",
    "item2"=>"3",
    "item4"=>"2",
    "item1"=>"1"
 );

知道如何做到这一点？谢谢.

我在PHP中使用Json是这样的:

$json = '{"total":"100", "page":"1", "records":"100", "rows": [ 
{"no":"1","part_number":"2","part_name":"3","price":"4","note":"8"}]}';

我想补充一下

"test1":"5","test2":"7"

进入JSON上面.

所以它会是这样的:

$json = '{"total":"100", "page":"1", "records":"100", "rows": [ 
    {"no":"1","part_number":"2","part_name":"3","price":"4","test1":"5","test2":"7","note":"8"}]}';

请帮我.如何在PHP中添加JSON中的属性？
