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) """
}

Given an absolute path to a CSV or any text file and a list of possible delimiters and assuming lines are up to 4096 characters long, I use
<?php
function guess_delimiter($file, $delimiters=[',',';'])
{
$h = fopen($file,'r');
$count = [];
foreach ($delimiters as $del) {
$count[$del] = 0;
while (($bufer = fgets($h, 4096)) !== false) {
$count[$del]+=substr_count($bufer, $del);
}
rewind($h);
}
fclose($h);
return array_search(max($count), $count);
}
