Here's the basic principal behind spiders.
$html = file_get_contents('http://www.example.com');
$dom = new DOMDocument();
@$dom->loadHTML($html);
// grab all the on the page
$xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//a");
for ($i = 0; $i < $hrefs->length; $i++) {
$href = $hrefs->item($i);
$url = $href->getAttribute('href');
echo $url.'<br />';
}
Just pass the string (e.g. the body part of an email) to the function, and it returns an array of Email Addresses contained in the String.
function extract_emails_from($string) {
preg_match_all("/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-]+/i", $string, $matches);
return $matches[0];
}If you catch the return value of function in $emails, you can parse it using foreach:
foreach($emails as $email) {
echo trim($email).'<br/>';
}
