Php 在一列中获取具有相同值的行

我从csv中获取的数据基于以下一些索引：

$filename=$_FILES["file"]["tmp_name"];      


     if($_FILES["file"]["size"] > 0)
     {
        $file = fopen($filename, "r");
        $rowCount = 0 ;
        $secondColumnArray = array();

        while (($getData = fgetcsv($file,  100000, ",")) !== FALSE)
         {
         if($rowCount >=0){

             if(strpos($getData[0],"Bestand")!==false){

             array_push($secondColumnArray, $getData[0]);

               }
             foreach ($secondColumnArray as $all_elements){

                $all_elements_refine = explode(',', $all_elements);

                $new_refine =  $all_elements_refine[0];

                $all_elements_refine1 = explode(';', $new_refine);

                $specialChars = array(" ", "\r", "\n", '"', "*");
                $replaceChars = array("", "", "");
                $all_elements_refine2 = str_replace($specialChars, $replaceChars, $all_elements_refine1);
                 print_r($all_elements_refine2);

             }

         }
                 ++$rowCount;

         }

        //echo "<pre>"; print_r($secondColumnArray);   echo "</pre>"; 
         fclose($file); 
     }

这些是我的csv中的实际行检查实际csv中的第四列，过滤csv后，我得到了重复的行

重复的行数：

$filename=$_FILES["file"]["tmp_name"];
if($_FILES["file"]["size"]>0){
    $file=fopen($filename,"r");
    $rowCount=0;
    $secondColumnArray=[];
    while(($getData=fgetcsv($file,100000))!==false){
        if($rowCount>=306){
            if(strpos($getData[0],"Bestand")!==false){
                array_push($secondColumnArray, $getData[0]);
            }
            foreach($secondColumnArray as $all_elements){
                print_r($all_elements);
            }
        }
        ++$rowCount;
    }
    fclose($file); 
}   

因此，我只想在第一列中列出具有最佳值的行以及如何获得这些值，请提供帮助。

这里有一个重写：

你的意思是：如果$all_elements[0]==Bestand{//保留它}？我不确定是否要筛选if之后的行或foreach内部的行。仍然显示所有数据。请给我一些$getData[0]和$all_元素的示例。请将此信息直接编辑到您的问题中。以下是git上我的模块的完整代码：复制是问题我已将此数据从CSV插入到表中，因此它正在复制entries@Shoaib你是说csv文件有重复的行，你想过滤它们，使所有行都是唯一的吗？好像这是一个额外的步骤？@Shaoib请在屏幕上打印几个$getData数组，并将它们添加到您的问题中，然后我将能够完善您的流程并消除重复项。我还对您的GitHub文件提出了一些其他建议。
