PHP解析文件到数组

我想弄清楚我在做什么，给了我错误的结果。PHP解析文件到数组

我有这样组成的文件：

2017/05/02 BA 86 23 39 89 5 
2017/05/02 CA 23 4 14 86 5 
2017/05/02 FI 71 26 19 15 6

2017/05/06 PA 2 33 65 72 61 
2017/05/06 RM 29 49 13 70 83 
2017/05/06 RN 30 81 55 37 41

正如你可以看到这是格式化这样：

DATE（标签）LETTERS（标签）N1（标签）N2（标签）N3 （标签）N4（标签）N5（标签）

第二行有相同的日期，并且更改了LETTERS和N_。

我需要这个文件插入到数据库中，但是这必须有一个线每一个日期，就像这样：

Date  |BA1|BA2|BA3|BA4|BA5|CA1|CA2|CA3|CA4|CA5|FI1|FI2|FI3|FI4|FI5| 
----------------------------------------------------------------- 
2017/05/02| 86 | 23| 39| 89|5 |23 | 4 | 14|86 |5..... 
----------------------------------------------------------------- 
2017/05/04|61 |70 |47 |71 |75 |26 |44 |16 |77 |55...

为什么我的代码不工作？

public function caricaStorico(){ 
     $this->load->helper('file'); 

     $storico = read_file(base_url("storico.txt")); 

     $splitter = explode("\n", $storico); 
     $data_estr = "-"; 
     $insert = []; 
     $arr_key = 0; 

     echo "<pre>"; 

     foreach ($splitter as $key => $value) { 
      $dati = explode("\t", $value); 

      if(count($dati)>1) { 

       $data_estr = $dati[0]; 

       $ruota = $dati[1]; 
       $n1 = $dati[2]; 
       $n2 = $dati[3]; 
       $n3 = $dati[4]; 
       $n4 = $dati[5]; 
       $n5 = $dati[6]; 

       switch ($ruota) { 
        case 'BA': 
         array_push($insert, ["data_estrazione" => $data_estr, "BA1" => $n1, 'BA2' => $n2, "BA3" => $n3, "BA4" => $n4, "BA5" => $n5]); 
         break; 

        case 'FI': 
         $insert[$arr_key] += ["FI1" => $n1, 'FI2' => $n2, "FI3" => $n3, "FI4" => $n4, "FI5" => $n5]; 
         break; 

        case 'MI': 
         $insert[$arr_key] += ["MI1" => $n1, 'MI2' => $n2, "MI3" => $n3, "MI4" => $n4, "MI5" => $n5]; 
         break; 

        case 'NA': 
         $insert[$arr_key] += ["NA1" => $n1, 'NA2' => $n2, "NA3" => $n3, "NA4" => $n4, "NA5" => $n5]; 
         break; 

        case 'PA': 
         $insert[$arr_key] += ["PA1" => $n1, 'PA2' => $n2, "PA3" => $n3, "PA4" => $n4, "PA5" => $n5]; 
         break; 

        case 'RM': 
         $insert[$arr_key] += ["RM1" => $n1, 'RM2' => $n2, "RM3" => $n3, "RM4" => $n4, "RM5" => $n5]; 
         break; 

        case 'TO': 
         $insert[$arr_key] += ["TO1" => $n1, 'TO2' => $n2, "TO3" => $n3, "TO4" => $n4, "TO5" => $n5]; 
         break; 

        case 'VE': 
         $insert[$arr_key] += ["VE1" => $n1, 'VE2' => $n2, "VE3" => $n3, "VE4" => $n4, "VE5" => $n5]; 
         break; 

        case 'RN': 
         $insert[$arr_key] += ["NZ1" => $n1, 'NZ2' => $n2, "NZ3" => $n3, "NZ4" => $n4, "NZ5" => $n5]; 
         break; 
       } 
      } 
      $arr_key = $arr_key+1; 
     } 

     print_r($insert); 
     echo "</pre>"; 

    }

如果我删除$input[$arr_key]和我做$input[0]我得到正确的结果只有第一个阵列上，而其他的则只能包含BA号码，你可以看到：

你可以通过使用日期作为数组的关键字来检查这一点：我用字符串变量来演示你的情况，所以你可以根据需要更改storico变量。

<?php 
function caricaStorico(){ 
     $storico = '2017/05/02 BA 86 23 39 89 5, 2017/05/02 CA 23 4 14 86 5, 2017/05/03 BA 86 23 39 89 5, 2017/05/03 CA 23 4 14 86 5'; 
     $splitter = explode(",", $storico); 
     $data_estr = "-"; 
     $insert = []; 

     echo "<pre>"; 
     foreach ($splitter as $key => $value) { 
      $dati = explode(" ", $value); 

      if(count($dati)>1) { 

       $data_estr = trim($dati[0]); 

       $ruota = $dati[1]; 
       $n1 = $dati[2]; 
       $n2 = $dati[3]; 
       $n3 = $dati[4]; 
       $n4 = $dati[5]; 
       $n5 = $dati[6]; 

       if(isset($insert[$data_estr]) && is_array($insert[$data_estr])) 
        $insert[$data_estr] += [ "data_estrazione" => $data_estr, $ruota."1" => $n1, $ruota."2" => $n2, $ruota."3" => $n3, $ruota."4" => $n4, $ruota."5" => $n5 ]; 
       else 
        $insert[$data_estr] = array("data_estrazione" => $data_estr, $ruota."1" => $n1, $ruota."2" => $n2, $ruota."3" => $n3, $ruota."4" => $n4, $ruota."5" => $n5); 
      } 
     } 

     print_r($insert); 
     echo "</pre>"; 

    } 

    caricaStorico(); 
?>

输出到这个代码：

Array 
(
    [2017/05/02] => Array 
     (
      [data_estrazione] => 2017/05/02 
      [BA1] => 86 
      [BA2] => 23 
      [BA3] => 39 
      [BA4] => 89 
      [BA5] => 5 
      [CA1] => 23 
      [CA2] => 4 
      [CA3] => 14 
      [CA4] => 86 
      [CA5] => 5 
     ) 

    [2017/05/03] => Array 
     (
      [data_estrazione] => 2017/05/03 
      [BA1] => 86 
      [BA2] => 23 
      [BA3] => 39 
      [BA4] => 89 
      [BA5] => 5 
      [CA1] => 23 
      [CA2] => 4 
      [CA3] => 14 
      [CA4] => 86 
      [CA5] => 5 
     ) 

)
