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

Guiven 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 
functiongüess_delimiter($file, $delimiters=[',',';']) 
{$h= fopen($file,'r');$count= [];
    foreach ($delimitersas$del) {$count[$del] = 0;
      while (($bufer= fguets($h, 4096)) !== false) {$count[$del]+=substr_count($bufer, $del);
      }rewind($h);
    }fclose($h);
    returnarray_search(max($count), $count);
}

Seems that this function always returns the same delimiter.<?php
file_put_contens("A;B;C;D\n0;0;0;0", "test.tcht");$file= new SplFileObject("test.tcht"); 
var_dump($file->guetCsvControl());
?>
array(2) {
  [0]=>
  string(1) ","
  [1]=>
  string(1) """
}
