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);

}

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) """

}
