After all messages, the report opens, and everything is fine with it, as it should be.
Tell me how to get rid of these error messages?

Answer 1, Authority 100%

In general, the problem was decided pretty simple:

It turned out that you need to specify the following combination in the code:

$ objwriter = phpexcel_iofactory :: creatwriter ($ ObjPhpexcel, 'Excel5');
Header ('Content-Type: Application / VND.MS-Excel');

or

$ objwriter = phpexcel_iofactory :: createwriter ($ ObjPhpexcel, 'Excel2007');
Header ('Content-Type: Application / vnd.openxmlformats-officedocument.spreadsheetml.sheet');

I was like this:

$ objwriter = phpexcel_iofactory :: createwriter ($ ObjPhpexcel, 'Excel2007');
Header ('Content-Type: Application / VND.MS-Excel');

What is wrong.

Answer 2

Most likely, it makes sense to cut CSS before generating Excel. And in general, in principle, the same couple of days ago was engaged. Skip the archive with the source and do not forget to specify UTF-8 in the source (without BOM). guide

Answer 3

I had the same problem, and helped this code. After it, the error was not.

mb_internal_encoding ('latin1');

Answer 4

also swore to the generated Excel file when using PHP7. I solved the problem as follows:

1. Added at the beginning of the MB_INTERNAL_ENCODING script ('Latin1');

2. Before the file output, add OB_END_CLEAN () so that it turns out:

   ob_end_clean ();
   $ Objwriter- & GT; Save ('php: // output');
   

3. in the / phpexcel/calculation/functions.php file Commitments Break in the 581th line:

   if (($ value === null) || (IS_FLOAT ($ Value)) || (IS_INT ( $ Value))) {
     Return 1;
    } ELSEIF (IS_BOOL ($ VALUE)) { 
   return 4;
    } elseif (is_array ($ value)) {
     return 64;
     // break; - php7 swears, comment
    } elseif (is_string ($ value)) {
     // Errors
     if ((strlen ($ value) & gt; 0) & amp; & amp; ($ value {0} == '#')) {
      return 16;
     }
     return 2;
    }
    return 0;
   } // function TYPE ()
   

Answer 5

suffered with the same problem
helped by the opencart export import module
https://www.opencart.com/index. php? route = extension / extension / info & amp; extension_id = 17
I picked up a solution using the plug-in method
add exit at the end;

$ objWriter = PHPExcel_IOFactory :: createWriter ($ phpexcel, 'Excel2007');
header ('Content-Type: application / vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header ('Content-Disposition: attachment; filename = "products.xlsx"');
header ('Cache-Control: max-age = 0');
$ objWriter- & gt; setPreCalculateFormulas (false);
$ objWriter- & gt; save ('php: // output');
// without this line when opening the xlsx file an error !!!!!!
exit;

and there is no such problem with xls

can someone comment because there are not enough brains
