CSVファイルにデータを挿入できませんPHP

Question

別のCSVファイルから目的のCSVファイルにデータを挿入中です。

CSVファイルは問題なしで問題なく作成されますが、ファイルに配列データを挿入することはありません。

最初の行にのみヘッダーが挿入されます。以下は

は、私がしようとしているコードです：

date_default_timezone_set('America/New_York'); 
set_time_limit(0); 
ini_set("memory_limit", -1); 

$realPath = realpath(dirname(__FILE__)); 
$path  = $realPath.'/3pltracking/'; 
$files = scandir($path); 
$FilePath = $path.$files[2]; 
$result = array(); 
$date  = date('m-d-Y_his'); 

if (file_exists($FilePath)) 
{ 
    if (($handle = fopen($FilePath, "r")) !== FALSE) 
     { 
      $i=0; 
      while (($data = fgetcsv($handle, 10000, ",")) !== FALSE) 
      { 
       $i++; 
       if($i==1) continue; 

       //$list = array('$data[2],$data[25],$data[4],$data[30],$data[41],$data[27]'); 
       echo $data[2].",".$data[25].",".$data[4].",".$data[30].",".$data[41].",".$data[27]; 
       echo "<br>"; 
       $list = array($data[2].",".$data[25].",".$data[4].",".$data[30].",".$data[41].",".$data[27]); 

      // the problem is here I believe as it is empty array if I check it outside while loop 
      } 

     fclose($handle); 

     $headers = array('ReferenceNumber', 'TotalCartons', 'ShipCarrier', 'TrackingNum', 'FreightPP', 'TotalWeight'); 

     $fp = fopen($realPath.'\3pltracking\TrackingFiles\Tracking_File_'.$date.'.csv', 'w'); 

     fputcsv($fp, $headers); 

     foreach ($list as $line) { 

      $val = explode(",", $line); 

      fputcsv($fp, $val); 

     } 

     fclose($fp); 

    } else { 

     $body = "File Not Found"; 

     } 
    } 

はここに私のCSVファイルのデータです：

この... str_getcsv($csvData)含むついて行くのように多くの方法があります。しかし、ここでは何かのために行くだろうold-school &少しひねり;-)。関連するCSVデータ構造を構築するために、RegexとLoopingコンストラクトを使用する関数を作成します。以下の機能は、どのように説明します。また、これは幾分ねじれた古い学校のアプローチだと言いましたが、だまされてはいけません... それはまだそれを行うので;-)。

<?php 

     $csvSourceFile   = __DIR__ . "/1.csv"; 
     $csvPreferredColumns = array('ReferenceNumber', 'TotalCartons', 'ShipCarrier', 'TrackingNum', 'FreightPP', 'TotalWeight'); 
     $newCsvStrut   = processCSVData($csvSourceFile, $csvPreferredColumns, __DIR__ . "/test.csv"); 

     /** 
     * @param $csvSource     // PATH TO THE MAIN CSV FILE

     * @return string 
     */ 
     function processCSVData($csvSource, array $csvPreferredColumns, $newCSVFileName=null){ 
      // GET THE CONTENTS OF THE CSV FILE & STORE IT IN A VARIABLE 
      $csvData  = file_get_contents($csvSource); 

      // SPLIT THE CONTENTS OF THE CSV FILE LINE BY LINE: THAT IS; AT THE END OF EACH LINE 
      // THUS CONVERTING THE DATA TO AN ARRAY... 
      $arrCsvLines = preg_split("#\n#", $csvData); 

      //FILTER OUT UNWANTED EMPTY VALUES FROM THE ARRAY
