php excel reader - problem reading multiple files at once | Libraries & Helpers

Hi,
i’m using Codeigniter 1.7.2 with the PHP Excel Reader found in the Codeigniter Wiki.
The standard use is to provide the filename of the Excel like this:

$params = array(‘file’ => $pathToFile, ‘store_extended_info’ => true,‘outputEncoding’ => ‘’);
    $this->load->library(‘Spreadsheet_Excel_Reader’, $params);

I read the XLS files in a model, but due to that, that i have to read multiple files i cannot assign in the model constructor the filename to be read. I do it later in the specific functions. My constructor looks like this:

function Chartsofc() {
        parent::Model();
        $params = array("store_extended_info" => false, "outputEncoding" => "");
        $this->load->library("Spreadsheet_Excel_Reader", $params);
    }

I provide only store_extended_info false and standard encoding.

Later on in the functions i call the ***read*** method of the php_excel_reader library like this:

function get_sheet_names($File) {
        $pathToFile = $this->xls_dir.$File;
        $this->spreadsheet_excel_reader->read($pathToFile);
        $sheetcount = $this->spreadsheet_excel_reader->sheetcount();
        for($i = 0; $i < $sheetcount; $i++){
            $sheet_names[$i] = $this->spreadsheet_excel_reader->boundsheets[$i]['name'];
        }
        return $sheet_names;
    }

I think the problem is that php-excel-reader opens the files but does not close them. There is no method to close them. Also i dont see that php-excel-reader is closing the files automatically.

I got a function which first reads all excels and gets me the sheetnames, but the for reading i need to get the sheet index. i wrote a function for that and i works on lone files, but when i read here more and twice it produces wrong results This is because php-excel-reader’s read function is called twice:
in $this->get_sheet_names($files[$index]);
and later in: $this->get_sheet_index_by_name(“xls\\” . $fs_arr[$index2][0] , $fs_arr[$index2][1]);

function get_tags() {
        $this->load->helper('directory');
        $files = directory_map('./xls/');
        $tags = array();
        $fs_arr = array(); 
        $init = 0;
        for ($index = 0; $index < count($files); $index++) {
            $sheets = $this->get_sheet_names($files[$index]);
            for ($index1 = $init; $index1 < count($sheets); $index1++) {
                $fs_arr[$init][0] = $files[$index];
                $fs_arr[$init][1] = $sheets[$index1];
                $init++;
            }
        }
    
        for ($index2 = 0; $index2 < count($fs_arr); $index2++) {
            $sheetIndex = $this->get_sheet_index_by_name("xls\\" . $fs_arr[$index2][0] , $fs_arr[$index2][1]);
            echo $fs_arr[$index2][1] . ' - ' . $sheetIndex . "\r\n";
        }
    
            return $tags;
        }

Then i got 4 XLS files and in produces a output of:

//name - index
        1_PKB - 0
        2_Inny - 1
        3_Tortowy - 2
        4_Liniowy - 3
        5_test - 4
        1_PKBO - 5
        2_BZT5 - 6
        3_PM10 - 7
        1_PKB - 0
        2_Inny - 1
        Arkusz1 - 10
        Arkusz2 - 11
        Arkusz3 - 12
        Rys_4_2_1 - 13

Instead of getting the right indexes of the sheets

//name - index
        1_PKB - 0
        2_Inny - 1
        3_Tortowy - 2
        4_Liniowy - 3
        5_test - 4
        1_PKBO - 0
        2_BZT5 - 1
        3_PM10 - 2
        1_PKB - 0
        2_Inny - 1
        Arkusz1 - 2
        Arkusz2 - 3
        Arkusz3 - 4
        Rys_4_2_1 - 0

Any ideas what to do? Is my seperated providing of the xls filename ok?
