// close connection
fclose($file);

Yes you can define some flag to count the row. Have a look on below solution. It will start printing from 5th row, also you can accesscolum by its index. For eg. for second column you can use $row[1]

$start_row = 5; //define start row
$i = 1; //define row count flag
$file = fopen("myfile.csv", "r");
while (($row = fgetcsv($file)) !== FALSE) {
    if($i >= $start_row) {
        print_r($row);
        //do your stuff
    }
    $i++;
}

// close file
fclose($file);

To clarify the numeracy in my snippets, the 5th row of data with be located at index [4]. The same indexing is used for column targeting -- the 4th column is at index [3].

A functional approach (assumes no newlines in values and is not set up with any extra csv parsing flags):

$starting_index = 4;
$target_column = 3;
var_export(
    array_column(
        array_slice(
            array_map(
                'str_getcsv',
                file('example.csv')
            ),
            $starting_index
        ),
        $target_column
    )
);

$disregard_rows = 4;
$target_column = 3;
$file = fopen("example.csv", "r");
while (($row = fgetcsv($file)) !== false) {
    if ($disregard_rows) {
        --$disregard_rows;
