  1. Hi all, I have a problem for sanitizing / validating a web address input. My personal favor is doing it with regex. I made a simple example with preg_replace <?php if (!empty($_POST['wbddrss']) ) { $wbddrss = $_POST['wbddrss']; $wbddrss = trim($wbddrss); var_dump($wbddrss); $validate = preg_replace('/<>/' , '', $wbddrss); var_dump($validate); } ?> But I would like to replace all chars that do not meet what is allowed. I guess the best solution would be to replace everything with a caret to negate. But it seems I cant find the right delimiters. This is the range of characters I would like to allow: A-Za-z0-9+&@#/%?=~_|!:,.;\(\) how is this done in a preg_replace function?
