Question

I’m using a simple function to write write arrays to a CSV-file, which look like this:

function writeToCSV($array) {
    $fp = fopen('programmes.csv', 'a');
    fputcsv($fp, $array);
    fclose($fp);
}

Simple as a pie. However, is there anyway to know what line-number the pointer is at? Because I want to be able to after 1000 lines to begin writing to a new file. Why? Because I need to be able to import them to a database later with some memory constraints, and to parse a CSV-file with 15000 lines is a no-no.

function writeToCSV($array) {
    $i = 1;
    $j = 1;
    $fp = fopen('programmes' . $j . '.csv', 'a');
    foreach($array as $fields) {
        if ($i % 1000 == 0) {
            fclose($fp);
            $fp = fopen('programmes' . $j . '.csv', 'a');
            $j = $j + 1;
        }
        fputcsv($fp, $fields);
        $i = $i + 1;
    }
    fclose($fp);
}
