How can I import data from an XLS file to MySQL?

Question

As I am trying to import MS Excel data to MySQL data base using the following code:

<?php  
    $db_username="root"; //database user name
    $db_password="";//database password
    $db_database="hr_mysql"; //database name
    $db_host="localhost";


    mysql_connect($db_host,$db_username,$db_password);
    @mysql_select_db($db_database) or die( "Unable to connect to database.");

    $handle = fopen("UploadIt.xls", "r"); //test.xls excel file name
    if ($handle)
    {
        $array = explode("\n", fread($handle, filesize("UploadIt.xls")));
    }

    $total_array = count($array);
    $i = 0;
    $Leave_Type_Id1="LTY001";
    $Leave_Type_Id2="LTY002";

    while($i < $total_array)
    {
    $data = explode(",", $array[$i]);    
    //$sql = "insert into test values ('$data[0]','$data[1]')";
    $sql = "update `hs_hr_employee_leave_quota` set `no_of_days_allotted`= {$data[0]} WHERE `employee_id`= {$data[0]} and `leave_type_id`= '{$Leave_Type_Id1}'";        
    $result = mysql_query($sql);
    $sql = "update `hs_hr_employee_leave_quota` set `no_of_days_allotted`= {$data[2]} WHERE `employee_id`= {$data[0]} and `leave_type_id`= '{$Leave_Type_Id2}'";        
    $result = mysql_query($sql);
    $i++;
    }
    if($result==false)
            echo "Not succed";  
    else 
    {
        echo "completed";   
    }

?>

And my .xls sheet is:

But I am getting error saying

htdocs\\Verify\\XL_To_DBTable.php line 28 - Undefined offset: 2

|1|2|5|

|2|3|5|

|3|3|4|

|4|3|9|

|5|4|1|

(Assume above one as xls sheet only)

Answer 1

You need to properly read the file as an MS Excel file. You are treating it as an ascii text file. You could manually dump the file to CSV format and parse it using similar logic to what you have already. Or you could use:

PHP Excel File Reader

and use that to parse the file, get the contents and then create the appropriate queries to be executed in mysql.
