Answer 1

I use this library to convert array to some other data format or vice versa.

CI - Rest Server

There you can find library/class Format (Format.php) that you can use to convert CSV to array then save it into your database. This class also support other format:

• xml – almost any programming language can read XML
• json – useful for JavaScript and increasingly PHP apps.
• csv – open with spreadsheet programs
• html – a simple HTML table
• php – Representation of PHP code that can be eval()’ed
• serialize – Serialized data that can be unserialized in PHP

EDIT:

This library works on CSV with delimiter "\n" on each row and "," on each of column, you can use it like this:

$this->load->library('format');

$string_csv = "YOUR CSV";        
$result = $this->format->factory($string_csv, 'csv')->to_array();

var_dump($result);

Just that simple. However as I said above if your have another delimiter then you have to adjust the library as your need. Here the main function to convert CSV to array:

function _from_csv($string)
{
    $data = array();

    // Splits
    $rows = explode("\n", trim($string));
    $headings = explode(',', array_shift($rows));
    foreach ($rows as $row)
    {
        // The substr removes " from start and end
        $data_fields = explode('","', trim(substr($row, 1, -1)));

        if (count($data_fields) == count($headings))
        {
            $data[] = array_combine($headings, $data_fields);
        }
    }

    return $data;
}

EDIT 2:

My example will work on this standard CSV format:

Heading1, Heading2, Heading3
"1","John","London"
"2","Brian","Texas"
