PHP函数从数组构建查询字符串
问题描述：
我正在寻找PHP函数的名称，以从键值对数组构建查询字符串.请注意，我正在寻找内置的PHP 函数来执行此操作，而不是自制程序(这一切都是Google搜索似乎返回的).有一个，我只是不记得它的名字或在php.net上找到它. IIRC的名称不是那么直观.
I'm looking for the name of the PHP function to build a query string from an array of key value pairs. Please note, I am looking for the built in PHP function to do this, not a homebrew one (that's all a google search seems to return). There is one, I just can't remember its name or find it on php.net. IIRC its name isn't that intuitive.
