The code for my import file is

<?php

// TODO
// including the file thats has the query function
require("../includes/config.php");

//ensuring proper usage
if($argc != 2)
{
    print("Usage : ./import path/to/file \n");
    exit(1);
}

// if the file is there and can be read
if(is_readable($argv[1]))
{
    $file = $argv[1];
    //open file
    $handle = fopen($file, "r");
    if ($handle == false)
    {
        print("Could not open file./n");
        exit(1);
    }

    // iterate over all the rows
    while($row = fgetcsv($handle, "\t"))
    {
        $countrycode = $row[0];
        $postalcode = $row[1];
        $placename = $row[2];
        $adminname1 = $row[3];
        $admincode1 = $row[4];
        $adminname2 = $row[5];
        $admincode2 = $row[6];
        $adminname3 = $row[7];
        $admincode3 = $row[8];
        $latitude = $row[9];
        $longitude = $row[10];
        $accuracy = $row[11];

        //query to insert into db
        CS50::query ("INSERT INTO places (country_code, postal_code, place_name, admin_name1, admin_code1,
                                         admin_name2, admin_code2, admin_name3, admin_code3, latitude,
                                         longitude, accuracy) VALUES (?,?,?,?,?,?,?,?,?,?,?,?)",$countrycode, $postalcode, $placename,
                                         $adminname1, $admincode1, $adminname2, $admincode2, $adminname3,
                                         $admincode3, $latitude, $longitude, $accuracy);

    }
}
else
{
    print("could not open/read file");
}

fclose($handle);

?>

Try this fgetcsv($handle, 0, "\t") instead of this fgetcsv($handle, "\t")

Why?

Because the second parameter of fgetcsv() is the length of the line. Thus, if you don't explicitly put it there, fgetcsv() will most likely think that your third parameter (delimiter "\t") is in fact the second.

You can kinda see what's wrong if you try to: print_r($row);

You should then see that $row is one array and there is no $row[1]

I haven't solved it yet myself but here is how you split it up:

$data = (list($country_code, $postal_code, $place_name, $admin_name1, $admin_code1, $admin_name2, $admin_code2, $admin_name3, $admin_code3, $latitude, $longitude, $accuracy) = fgetcsv($file, 0, "\t"));

It should then be like this: Array ( [0] => US [1] => 34034 [2] => APO [3] => [4] => AA [5] => Dillon [6] => 033 [7] => [8] => [9] => 33.0364 [10] => -82.2493 [11] => 1 )

Hope this was helpful. Sorry if it is poorly explained.
