this function returns an array with a list of all urls matched in a string, including src, href and
url;
function get_urls($string) {
$types = array("href", "src", "url");
while(list(,$type) = each($types)) {
preg_match_all
("|$type\=\"?'?
?([[:alnum:]:?=&@/._-]+)\"?'??|i",
$string, &$matches);
$ret[$type] = $matches[1];
}
return $ret;
}
$html = implode(file( 'http://www.uol.com.br/'
));
print_r(get_urls($html));
