column1-1;                column1-2;column1-3;column1-4

column1-4-1

column1-4-2

column1-4-3
column2-1;                column2-2;column2-3;column2-4

column2-4-1

column2-4-2

$file = $_SERVER['DOCUMENT_ROOT'].'/import.csv';
if ($handle = fopen($file, "r")) {
    while (($csv = fgetcsv($handle, 0, ';', '"','\\')) !== false) {
        print_r($csv);
    }
}
