Question

I am trying to generate a query string. The function works for non utf8 characters, but utf8 characters show up as blank.

function

function qs_search($qs) {
  parse_str($_SERVER['QUERY_STRING'], $query_string);
  $query_string['search'] = basename($qs);
  return http_build_query($query_string);
}

These are the results…

qs_search(‘regular’);

index.php?list&search=regular

qs_search(‘Синодальный’);

index.php?list&search=

As per the comments, I still have no idea why you’re using basename, however, using set_locale will work in PHP 5.2+:

<?php
    function qs_search($qs) {
        $query_string = array();
        $query_string['search'] = basename($qs);
        return http_build_query($query_string);
    }
    setlocale(LC_ALL, "en_US.UTF8");
    var_dump(qs_search("regular"));
    var_dump(qs_search("Синодальный"));
?>

As stated, this will NOT work on PHP 5.0.0 – 5.1.6. Click to see results.

Edit:

Apparently the developers of Drupal had the same problem and created their own basename function because of this bug, and that should fix your issue on PHP 5.0.0 – 5.1.6.
