PHPExcel只将第一个工作表导入到Mysql中

Question

我找到了这个代码并且它工作得很好，除了它将所有工作表导入我的MySql数据库并且我只打算使用第一个工作表。

<?php  
 $connect = mysqli_connect("localhost", "root", "", "test_db");  
 include ("PHPExcel/IOFactory.php");  
 $html="<table border='1'>";  
 $objPHPExcel = PHPExcel_IOFactory::load('example.xls');  
 foreach ($objPHPExcel->getWorksheetIterator() as $worksheet)   
 {  
  $highestRow = $worksheet->getHighestRow();  
  for ($row=2; $row<=$highestRow; $row++)  
  {  
       $html.="<tr>";  
       $name = mysqli_real_escape_string($connect, $worksheet-     >getCellByColumnAndRow(0, $row)->getValue());  
       $email = mysqli_real_escape_string($connect, $worksheet->getCellByColumnAndRow(1, $row)->getValue());  
       $sql = "INSERT INTO tbl_excel(excel_name, excel_email) VALUES   ('".$name."', '".$email."')";  
       mysqli_query($connect, $sql);  
       $html.= '<td>'.$name.'</td>';  
       $html .= '<td>'.$email.'</td>';  
       $html .= "</tr>";  
  }  
 }  
 $html .= '</table>';  
 echo $html;  
 echo '<br />Data Inserted';  
 ?>  

我试过了 $ objWorksheet = $ objPHPExcel-＆gt; setActiveSheetIndex（0）; 以及getSheet（0）; 还有很多其他事情无济于事。
