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) """
}
