To produce RFC 4180 conforming output, do not use fputcsv but encode manually, like this:

function rfccsv($arr){
    foreach($arr as &$a){
        $a=strval($a);
        if(strcspn($a,",\"\r\n")<strlen($a))$a='"'.strtr($a,array('"'=>'""')).'"';
    }
    return implode(',',$arr);
}
echo rfccsv(array(.....))."\n";
