在Excel中搜索PHP與PHP

Question

我想通過使用PHPExcel的第一個單元格值來查找Excel表格中行的最後單元格值。用戶輸入行中第一個單元格的值（這是「command」參數），如果它存在於表格中，我的函數應該跳轉到行的最後一個單元格並返回值。這是我的代碼：

public function search($command, $excelobj) { 
    foreach ($excelobj->getWorksheetIterator() as $worksheet) { 
     foreach ($worksheet->getRowIterator() as $row) { 
      $rowiterator = $worksheet->getRowIterator(); 
      foreach ($row->getCellIterator() as $cell) { 
       $celliterator = $row->getCellIterator(); 
       $head = $celliterator->current()->getValue(); 
       if(strcmp($head, $command)) { 
        for ($i = 0; $i == 8; $i++) { 
         $celliterator->next(); 
        } 
        return $cell->getValue(); 
       } 
      } 
     } 
    } 
    return false; 
} 

由於某些原因它總是返回錯誤。

我解決它自己，這個代碼正常工作：

public function search($command, $excelobj) { 
    foreach ($excelobj->getWorksheetIterator() as $worksheet) { 
     foreach ($worksheet->getRowIterator() as $row) { 
      $rowiterator = $worksheet->getRowIterator(); 
      $celliterator = $row->getCellIterator(); 
      $celliterator->setIterateOnlyExistingCells(true); 
      $head = $celliterator->current()->getValue(); 
      while (strcmp($head, $command) !== 0 && $rowiterator->valid()) { 
       $rowiterator->next(); 
       $row = new PHPExcel_Worksheet_Row($worksheet, $rowiterator->key()); 
       $celliterator = $row->getCellIterator(); 
       $head = $celliterator->current()->getValue(); 
      } 
      for ($i = 0; $i <= 7; $i++) { 
       $celliterator->next(); 
      } 
      return $celliterator->current()->getValue(); 
     } 
    } 
    return false; 
}
