MySQL export ID to Excel for scientific counting method, how to deal with

MySQL export ID to Excel for scientific notation, what to do?
I am through phpexcelclasses the following method to export MySQL data to Excel, but when the identity card, it becomes the scientific notation, what method can be imported in advance to import the ID number of the Excel field set to text, to display the identity card normally?
Set_include_path (Get_include_path (). ";" . '.. /common/phpexcelclasses/');
Include ' phpexcel.php ';
Or include ' phpexcel/writer/excel2007.php ';
Include ' phpexcel/writer/excel5.php '; For the output. xls
Create an Excel
$objPHPExcel = new Phpexcel ();
Save excel-2007 Format
$objWriter = new phpexcel_writer_excel2007 ($objPHPExcel);
$objWriter->setoffice2003compatibility (TRUE);
$objWriter = new Phpexcel_writer_excel5 ($objPHPExcel); /
$objPHPExcel->setactivesheetindex (0);
$objPHPExcel->getactivesheet ()->setcellvalue (' A1 ', ' student number ');
$objPHPExcel->getactivesheet ()->setcellvalue (' B1 ', ' Social Security Number ');
..............................
$objWriter->save ("Info.xls");

------Solution--------------------
Use String type
------Solution--------------------
The exported value is automatically converted to characters before the symbol table space is added
------Solution--------------------
Single quotation mark with one half corner before the exported value
------Solution--------------------
