我使用 WampServer 版本 2.2 php5.3.13 使用 Windows 7
我把我的项目放在 www
并在我的项目执行期间显示此错误
Fatal error: Call to undefined function http_build_url() in C:\wamp\www
在我的项目的源代码中，我使用这种语法
$url = http_build_url($url);
我想我需要配置 wamp

- 检查您的扩展文件夹中的
php_http.dll文件。 - 如果文件存在，请检查您的（或任何其他包含的 .ini-s）
php_http中是否启用了扩展名php.ini - 如果文件不存在，要么从http://downloads.php.net/pierre/单独下载它，要么从http://museum.php.net/与其他 pecl 扩展（您可能需要其中一些）一起下载php5/pecl-5.2.6-Win32.zip。调整您的
php.ini以启用扩展。 - 重新启动您的网络服务器。
