        if (($handle = fopen($file, 'r')) !== FALSE) { 
            $i = 0; 
            while (($lineArray = fgetcsv($handle, 4000, $delimiter, '"')) !== FALSE) { 
                for ($j = 0; $j < count($lineArray); $j++) {

        return $arr; 
    // Call the function convert CSV To Array
    $data = convertCsvToArray($filePath, ',');
    // Set the number of elements (minus 1 because we shift off the first row)

    $labels = array_shift($data);  
    foreach ($labels as $label) {
        $keys[] = $label;
    // assign keys value to ids, we add new parameter id here
    $keys[] = 'id';
    for ($i = 0; $i < $count; $i++) {
        $data[$i][] = $i;
    // combine both arrays
    for ($j = 0; $j < $count; $j++) {
        $d = array_combine($keys, $data[$j]);
        $newArray[$j] = $d;
    // convert array to JSON PHP using the json_encode()
