Extract all email addresses from a web page in PHP

Hi, today I had to write A PHP script to extract all email addresses on a web page by its URL. I wanted to make a large database of emails for an email marketing campaign. So That I feel sharing this code will help some one to save his time in writing a code from scratch.

First I put an html form which action is set to current index page, the form submit will pass the URL field value to
the same page.

<form method="post">
    <input type="text" name="url" size="65" value="<?php echo $the_url;  ?>"/><br />

  <input type="submit" value="Show Emails" />

The i get the URL address value from Hash and scan the page by getting its content using file_get_contents function. Using
my Regex function I match the content of the page and out put all emails.

  $the_url = isset($_REQUEST['url']) ? htmlspecialchars($_REQUEST['url']) : '';
  if (isset($_REQUEST['url']) && !empty($_REQUEST['url'])) {
    // fetch data from specified url
    $text = file_get_contents($_REQUEST['url']);
  // parse emails
  if (!empty($text)) {
    $res = preg_match_all(
    if ($res) {
      foreach(array_unique($matches[0]) as $email) {
        echo $email . "<br />";
    else {
      echo "No emails found.";

<form><input type="text" name="Aaa" > </form>
