Description:
------------
---
From manual page: https://php.net/mysqli.set-local-infile-handler
---
An error occurs at the methods "set_local_infile_handler" and "set_local_infile_default" of MySQLi class. Even the code sample in PHP documentation does not work.

Test script:
---------------
<?php
  $db = mysqli_init();
  $db->real_connect("localhost","root","","test");
  function callme($stream, &$buffer, $buflen, &$errmsg) {
    $buffer = fgets($stream);
    echo $buffer;
    $buffer = strtoupper(str_replace(",", "\t", $buffer));
    return strlen($buffer);
  }
  echo "Input:\n";
  $db->set_local_infile_handler("callme");
  $db->query("LOAD DATA LOCAL INFILE 'input.txt' INTO TABLE t1");
  $db->set_local_infile_default();
  $res = $db->query("SELECT * FROM t1");
  echo "\nResult:\n";
  while ($row = $res->fetch_assoc()) {
    echo join(",", $row)."\n";
  }
?>


Expected result:
----------------
I expect that code will work successfully? it doesn't matter what resalt is.

Actual result:
--------------
But this error appears:

 Fatal error: Uncaught Error: Call to undefined method mysqli::set_local_infile_handler()
