Note that this function does not magically guess the CSV control from a given file, rather it returns what has been priorly set with SplFileObject::setCsvControl().

Seems that this function always returns the same delimiter.

<?php
file_put_contents
("A;B;C;D\n0;0;0;0", "test.txt");

$file = new SplFileObject("test.txt");
var_dump($file->getCsvControl());
?>

array(2) {
  [0]=>
  string(1) ","
  [1]=>
  string(1) """
}
