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().

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);
}

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) """
}
