Hướng dẫn xử lý ký tự đặc biệt khi xuất excel 

xử lý kí tự đặc biệt trong nukeviet chúng ta sử dụng hàm 

nv_htmlspecialchars

Chuyển đổi các kí tự đặc biệt thành chuỗi 
&  	=>	  &  
\  	=>	  '  
"  	=>	  "  
<  	=>	  &lt;  
>  	=>	  &gt;  
\\  	=>	  &#x005C;  
/  	=>	  &#x002F;  
(  	=>	  &#40;  
)  	=>	  &#41;  
*  	=>	  &#42;  
[  	=>	  &#91;  
]  	=>	  &#93;  
!  	=>	  &#33;  
=  	=>	  &#x3D;  
#  	=>	  &#x23;  
%  	=>	  &#x25;  
^  	=>	  &#x5E;  
:  	=>	  &#x3A;  
{  	=>	  &#x7B;  
}  	=>	  &#x7D;  
`  	=>	  &#x60;  
~  	=>	  &#x7E;  
 

Cú pháp: 

$objPHPExcel->getActiveSheet()->setCellValue(PHPExcel_Cell::stringFromColumnIndex($col) . $rowIndex, nv_htmlspecialchars ($title));

Lấy dữ liệu xuống và xử lý ký tự đặc biệt 
// Hien thi danh sach cau tra loi
			$i = $rowIndex + 1;
			$number = 1;
			foreach ($array_data as $data) {
				// $date_time =  date('d/m/Y h:i:s A',$data['publtime']);
				$data['publtime'] = date('d/m/Y',$data['publtime']);
				$j = $columnIndex;
				foreach ($array_title as $field => $title) {  
					$col = PHPExcel_Cell::stringFromColumnIndex($j);
					$CellValue = $data[$field];
					$objPHPExcel->getActiveSheet()->setCellValue($col . $i, nv_htmlspecialchars ($CellValue));
					$j++;
				}
				$i++;
			}
Dưới đây là mẫu xuất excel
