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) """
}
