Question

我正在尝试在PHP中执行过滤功能。我已经开始做吼了：

function handleDuplicates($duplicateMonthReportsArray,$NodeReports,$whatToCompare){
    foreach ($duplicateMonthReportsArray as $duplicate) {
       $duplicateReportsArray = $NodeReports->nodeReports[$duplicate]->indvReports;
       var_dump($duplicateReportsArray); //Prints out what I have written bellow
       foreach ($duplicateReportsArray as $duplicateReport) {
           if($whatToCompare==="both"){
               //Return higest [NoSamples] and latest ["StopTime"] (If possible).
           }
           else if($whatToCompare==="latest"){
               //Return array with latest ["StopTime"]          
           }else{
              //Return array with higest [NoSamples] (If both same like the bellow case then return latest "StopTime")

           }
       }
    }
}

var_dump打印出下面的文字：

array(2) {
  [""AU Feb-13",201302282                                                                                                                                                                                                            "]=>
  array(2) {
    ["StopTime"]=>
    string(23) "2013-02-28 23:00:00.000"
    ["NoSamples"]=>
    string(5) "673.0"
  }
  [""AU Feb-13",201302282                                                                                                                                                                                                            "]=>
  array(2) {
    ["StopTime"]=>
    string(23) "2013-02-28 23:55:00.000"
    ["NoSamples"]=>
    string(5) "673.0"
  }
}

我想要做的是在代码中打印为注释。我想做一个自定义的过滤器函数，它循环遍历一个看起来像我上面写的var_dump的对象数组，并返回带有最高“StopTime”，“higest NoSamples”或两者的数组实例（如果可能，否则只返回最大的“NoSamples”。

您将如何实施此过滤功能？在我的情况下是否准备好使用任何已完成的过滤器函数，它需要一组数组并对其执行过滤？

提前多多谢谢。

假设$ arrays变量包含var_dump数据：

$maxStopTime = "";    
$maxStopTimeIx = 0;

$maxNoSamples = "";
$maxNoSamplesIx = 0;

foreach ($arrays as $k=>$array) {
   if ($array['StopTime'] > $maxStopTime) {
      $maxStopTimeIx = $k;
      $maxStopTime = $array['StopTime'];
   }

   if ($array['NoSamples'] > $maxNoSamples) {
      $maxNoSamplesIx = $k;
      $maxNoSamples = $array['NoSamples'];
   }
}

$maxStopTimeArray = $arrays[$maxStopTimeIx];
$maxNoSamplesArray = $arrays[$maxNoSamplesIx];

php中的自定义Filter数组值
