here's how you can turn plain text into html, turning plain urls into hyperlinks:
function urlparse($m) {
$t = $m[0];
if (preg_match(',^\w+://,', $t))
return "<a href=\"$t\">$t</a>";
return "<a href=\"http://$t\">$t</a>";
}
function parseplaintext($d) {
$pd = str_replace("\n", "<br />", htmlspecialchars($d));
$pd = preg_replace_callback(
'°(\w+://([^\s/:@]+(:[^\s/:@]++)?@)?|\bwww\.)' .
'[\w.]+(:\d+)?(/([-\w?&%+#;|@]*[\w-])?)?°is', "urlparse", $pd);
return $pd;
}
