Extract URL(s) from Link(s)

This is a script which extracts URLs from Links. The function gets the content from the HREF attribute and ignores the non-urls like: “javascript: openWindow()”.

Using Regular Expressions

$url = 'http://www.php.net/';

// Fetch page
$string = FetchPage($url);

// Regex that extracts the urls from links

$links_regex = '/<a[^/>]*'.

'href=["|\']([^javascript:].*)["|\']/Ui';

preg_match_all($links_regex, $string, $out, PREG_PATTERN_ORDER);

echo "<pre>"; print_r($out); echo "</pre>";

function FetchPage($path)
{
$file = fopen($path, "r"); 

if (!$file)
{
exit("The was a connection error!");
} 

$data = '';

while (!feof($file))
{
// Extract the data from the file / url

$data .= fgets($file, 1024);
}
return $data;
}
?>
