Undefined variable in example.php if missing page title

What steps will reproduce the problem?
1. Fetch a URL that is wrong, or the HMTL $response is missing <title> tags, or 
if there is a server configuration issue that is breaking cURL
2. Run example.php

What is the expected output? What do you see instead?

No output, as expected, but PHP raises:
PHP Notice:  Undefined variable: title in /example.php on line 19

What version of the product are you using? On what operating system?

r20 Sep 12, 2010 on CentOS 6.2

Please provide any additional information below.

The PHP notice can be fixed by moving the echo $title inside the if block. e.g.,

  if (preg_match("~<title>(.*?)</title>~i", $response, $out)) {
    $title = $out[1];
    echo "<b>$title</b><br />";
  } else {
    echo "<i>page title not found</i><br />";
  };
