3,使用示例：

注意：这里的编码要根据你的excel文件编码来定，这个示例只是取第一行数据，其它的可以例推。

  1. error_reporting(E_ALL);
  2. /** Include path **/
  3. set_include_path('../../lib/PHPExcel/');

  5. /** PHPExcel_IOFactory */
  6. include 'PHPExcel/Reader/reader.php';

  8. $data = new Spreadsheet_Excel_Reader();
  9. //设置文本输出编码
  10. $data->setOutputEncoding('utf-8');
  11. //读取Excel文件
  12. $data->read("2.xls");
  13. //$data->sheets[0]['numRows']为Excel行数
  14. $key=array();
  15. for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {
  16.     for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) {
  17.         //显示每个单元格内容
