The following seems to work for me.

<?php
$filename = "poll_result.txt";
if (isset($_POST['vote'])) {
$vote = intval($_POST['vote']); // get this vote
$content = file($filename); // read result file
$array = explode("||", $content[0]);
$yes = intval($array[0]); // get stored results
$no = intval($array[1]);
if ($vote == 1) $yes++; // increment one
if ($vote == 0) $no++;
$insertvote = $yes."||".$no; // new result string
}
else {
$insertvote = "0||0\n"; // reset result string
$yes = 0;
$no = 0;
}
$fp = fopen($filename,"w"); // store results
fputs($fp,$insertvote);
fclose($fp);
echo <<<EOT

</form>
<p>The results so far:<br>
Yes: $yes votes<br>
No: $no votes</p>
</body>
</html>
EOT;
?>
