使用带有Spreadsheet_Excel_Reader库的codeigniter在php中读取xls文件

Question

am trying to read an excel file (i.e xls) and import the data to mysql database and am using codeigniter 2.0.1 framework.

here are the codes to generate query

    public function read_file($table = 'organization', $filename = 'test.xls') {

    $pathToFile = './uploads/' . $filename;
    $this->load->library('Spreadsheet_Excel_Reader');
    $data = new Spreadsheet_Excel_Reader($pathToFile);
    $sql = "INSERT INTO $table (";
    for($index = 1;$index <= $data->sheets[0]['numCols']; $index++){
        $sql.= strtolower($data->sheets[0]['cells'][1][$index]) . ", ";
    }

    $sql = rtrim($sql, ", ")." ) VALUES ( ";
    for ($i = 2; $i <= $data->sheets[0]['numRows']; $i++) {
        for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) {
            $sql .= "\"" . $data->sheets[0]['cells'][$i][$j] . "\", ";
        }
        echo  rtrim($sql, ", ")." ) <br>";
    }

}

the values generated in the loop are duplicated , i cant find the problem with the loop...

Here is the result after running the function above:

INSERT INTO organization (userid, datestamp, kata, kaya, kaya_zenye_vuoo, vyoo_vyenye_bamba, mifuniko, matumizi_mifuniko, uzuiaji_inzi, usafishikaji_sakafu, usitiri, uezekaji, milango_inayofungika, harufu, wadudu, sabuni, maji, vibuyuchirizi ) VALUES ( "[e-mail]", "2011-04-10 08:21", "Chunyu", "2", "4", "5", "3", "56", "5", "6", "8", "45", "7", "8", "9", "8", "9", "8" ) 
INSERT INTO organization (userid, datestamp, kata, kaya, kaya_zenye_vuoo, vyoo_vyenye_bamba, mifuniko, matumizi_mifuniko, uzuiaji_inzi, usafishikaji_sakafu, usitiri, uezekaji, milango_inayofungika, harufu, wadudu, sabuni, maji, vibuyuchirizi ) VALUES ( "[e-mail]", "2011-04-10 08:21", "Chunyu", "2", "4", "5", "3", "56", "5", "6", "8", "45", "7", "8", "9", "8", "9", "8", "[e-mail]", "2011-04-10 08:21", "Chunyu", "2", "4", "5", "3", "56", "5", "6", "8", "45", "7", "8", "9", "8", "9", "8" ) 
INSERT INTO organization (userid, datestamp, kata, kaya, kaya_zenye_vuoo, vyoo_vyenye_bamba, mifuniko, matumizi_mifuniko, uzuiaji_inzi, usafishikaji_sakafu, usitiri, uezekaji, milango_inayofungika, harufu, wadudu, sabuni, maji, vibuyuchirizi ) VALUES ( "[e-mail]", "2011-04-10 08:21", "Chunyu", "2", "4", "5", "3", "56", "5", "6", "8", "45", "7", "8", "9", "8", "9", "8", "[e-mail]", "2011-04-10 08:21", "Chunyu", "2", "4", "5", "3", "56", "5", "6", "8", "45", "7", "8", "9", "8", "9", "8", " [e-mail]", "2011-04-10 08:21", "Chunyu", "2", "4", "5", "3", "56", "5", "6", "8", "45", "7", "8", "9", "8", "9", "8" )

I cannot test it, but... :

    public function read_file($table = 'organization', $filename = 'test.xls') {

    $pathToFile = './uploads/' . $filename;
    $this->load->library('Spreadsheet_Excel_Reader');
    $data = new Spreadsheet_Excel_Reader($pathToFile);
    $sql = "INSERT INTO $table (";
    for($index = 1;$index <= $data->sheets[0]['numCols']; $index++){
        $sql.= strtolower($data->sheets[0]['cells'][1][$index]) . ", ";
    }

    $sql = rtrim($sql, ", ")." ) VALUES ( ";
    for ($i = 2; $i <= $data->sheets[0]['numRows']; $i++) {
        $valuesSQL = '';
        for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) {
            $valuesSql .= "\"" . $data->sheets[0]['cells'][$i][$j] . "\", ";
        }
        echo $sql . rtrim($valuesSql, ", ")." ) <br>";
    }
}
