phpexcel 导入 excel出现问题，求解答！！！

使用phpexcel导入excel出现问题，怎么解决？？？
exception 'PHPExcel_Reader_Exception' with message 'Could not open 20131025085845.xls for reading! File does not exist, or it is not readable.' in E:\wamp\www\student_message\ThinkPHP\Extend\Vendor\Excel\PHPExcel\Shared\OLERead.php:80 Stack trace: #0 E:\wamp\www\student_message\ThinkPHP\Extend\Vendor\Excel\PHPExcel\Reader\Excel5.php(1067): PHPExcel_Shared_OLERead->read('20131025085845....') #1 E:\wamp\www\student_message\ThinkPHP\Extend\Vendor\Excel\PHPExcel\Reader\Excel5.php(571):

执行代码如下：
public function read($filename,$encode,$file_type){

if(strtolower ( $file_type )=='xls')//判断excel表类型为2003还是2007

{

Vendor("Excel.PHPExcel.Reader.Excel5");

$objReader = PHPExcel_IOFactory::createReader('Excel5');

}elseif(strtolower ( $file_type )=='xlsx')

{

Vendor("Excel.PHPExcel.Reader.Excel2007");

$objReader = PHPExcel_IOFactory::createReader('Excel2007');

}

$objReader->setReadDataOnly(true);

$objPHPExcel = $objReader->load($filename);

$objWorksheet = $objPHPExcel->getActiveSheet();

$highestRow = $objWorksheet->getHighestRow();

$highestColumn = $objWorksheet->getHighestColumn();

$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);

$excelData = array();

for ($row = 1; $row <= $highestRow; $row++) {

for ($col = 0; $col < $highestColumnIndex; $col++) {

$excelData[$row][] =(string)$objWorksheet->getCellByColumnAndRow($col, $row)->getValue();

}

}

return $excelData;

}

楼主我也遇到了同样的问题，百度了一下我得出的靠谱结论是： 'Could not open 20131025085845.xls for reading! File does not exist, or it is not readable.说明excel文件不存在或者不可读，原因很可能是文件夹有权限，我用的xampp，我看了下我tmp文件夹（存放临时文件的）的属性，果然是只读，不仅如此，所有的文件夹及其文件都是只读。但是修改属性没用啊，修改完后右击还是只读，我也很郁闷..

文件名不能用中文，只能用英文！！！！！！

我用的英文的还是没用
