PHP - 如何从表单提交中删除尾随变量？

When I submit a form, I get url's that look like this http://localhost/offstreams/search/?search=fuzz. I want the URL to look like so: http://localhost/offstreams/search/fuzz.

Here is my HTML Form:

<form action="<?php echo BASE_URI . "search/"; ?>" method='get' class='searchbarForm'>
    <input type='text' name='search' id='searchbar' placeholder='Search...'/>
</form>

My PHP Code:

if (isset($_GET['search'])) {
    echo $_GET['search'];   
}

My .htaccess:

RewriteEngine On
RewriteBase /
RewriteRule ^search/(.*)$ ./offstreams/searchs/search.php?search=$1 [QSA]

HERE'S THE THING: The result is printed when I go to http://localhost/offstreams/search/fuzz - It works absolutely fine, BUT I want the page to submit to that link instead of the ugly URL from the top. How do I submit a form and have the $_GET['search'] to work with mod_rewrite?

This isn't exactly what you were asking but it should work.

if (isset($_GET['search'])) {
    if (strpos($_SERVER['REQUEST_URI'], '?') !== false) {
       header('Location: http://'.$_SERVER['HTTP_HOST'].'/offstreams/search/'.urlencode($_GET['search']));
       exit();
    }
    echo $_GET['search'];   
}

This will search for a ? in the current url and then format the url to the way you want it.
