excel数据导入mysql，当excel数据行数大概少于4500行的时候正常，
当数据大于4500行后报错，异常提示：
Fatal error: Uncaught exception 'Exception' with message 'Could not open for reading! File does not exist, or it is not readable.' in D:\PHPpro\PHPTest\OLERead.php:72 Stack trace: #0 D:\PHPpro\PHPTest\reader.php(381): PHPExcel_Shared_OLERead->read('') #1 D:\PHPpro\PHPTest\import.php(34): Spreadsheet_Excel_Reader->read('') #2 {main} thrown in D:\PHPpro\PHPTest\OLERead.php on line 72求助帮忙。
