PHP RegExp Help!

[a2rodger]

I have the following regular expression which is stripping all unwanted characters before sending a variable to a url.

$url = preg_replace('~[^\\pL0-9_]+~u', '_', $url);

The problem is I would like to keep single quotation marks or encode them for the url so that I may retrieve them on the next page. The function above is currently getting rid of all single quotes.

I hacked this together and am not sure how to do this. Please Help!

Just add a single quote (preceeded with a backslash) to the regex, then urlencode() the url.
[php]
$_url = "something'with ' sing l e ' quotes in";
echo urlencode(preg_ replace('~[^\\pL0-9_\']+~u', '_', $_url));
[/php]

That did the trick. Thanks!

That did the trick. Thanks!

No probs!
remember to urldecode() when you want to get the url params!
