Reading an XLS file with codeigniter 2.0

问题

I've got the following problem.

I am trying to read an excel 97 - 2003 (XLS) file. The file is located within the codeigniter folder. Currently i am using the spreadsheet_excel_reader.php library to read the XLS file.

Unfortunately i cannot get it working, it does recognize the XLS file and also reads the file, but when it's done parsing the file, it returns NULL

This is what my method looks like.

$CI =& get_instance();

$this->data_file = "./xls/BolFeed.xls"; //The XLS file and folder

//$CI->spreadsheet_excel_reader->setOutputEncoding('CP1251'); //I've added this one into the library itself.

$CI->spreadsheet_excel_reader->read($this->data_file); //Start reading the XLS file

$this->data_array = $this->spreadsheet_excel_reader->sheets[0]; //This should return my XLS but only returns NULL

var_dump($this->data_array);
die;

I think the method does not cause the problem, but the XLS parse library does.

I hope you guys can help me out, because i've been struggling with this problem for days.

I am using PHP 5.3.0 and CI 2.0.0

Thanks for your efforts.

回答1:

shouldn't $this->spreadsheet_excel_reader->sheets be $CI->spreadsheet_excel_reader->sheets as you are calling $CI->spreadsheet_excel_reader->read in the line above

回答2:

if you do count($this->spreadsheet_excel_reader->sheets) before or after var_dump does it show that the array isn't empty?

And from the docs, it seems like you need to do more that sheets to see data:

$this->spreadsheet_excel_reader->dump($row_numbers=false,$col_letters=false,$sheet=0,$table_class='excel');
