function drupal_http_build_query
drupal_http_build_query(array $query, $parent = '')
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.
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.
Return value
A rawurlencoded string which can be used as or appended to the URL query string.

']' : rawurlencode($key)); // Recurse into children. if (is_array($value)) { $params[] = drupal_http_build_query($value, $key); } // If a query parameter value is NULL, only append its key. elseif (!isset($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); }
