Parses an array into a valid, rawurlencoded query string.
This differs from http_build_query() as we need to rawurlencode() (instead of urlencode()) all query parameters.
$query: The query parameter array to be processed, e.g. $_GET.
$parent: Internal use only. Used to build the $query array key for nested items.
A rawurlencoded string which can be used as or appended to the URL query string.
public function httpBuildQuery(array $query, $parent = '') {
$params = array();
foreach ($query as $key => $value) {
$key = $parent ? $parent . '[' . rawurlencode($key) . ']' : rawurlencode($key);
// Recurse into children.
if (is_array($value)) {
$params[] = $this
->httpBuildQuery($value, $key);
}
elseif (!isset($value)) {
$params[] = $key;
}
else {
// For better readability of paths in query strings, we decode slashes.
$params[] = $key . '=' . str_replace('%2F', '/', rawurlencode($value));
}
}
return implode('&', $params);
