PHPMailer 是一個功能豐富的函式庫，以下是用 PHPMailer 通過遠端 SMTP 認證發送郵件的例子：

require()
require() is identical to include() except upon failure it will produce a fatal E_ERROR level error. In other words, it will halt the script whereas include() only emits a warning (E_WARNING) which allows the script to continue.
這幾個的區別呢 經常會聽到有人討論
連一些PHPER面試都會出這個題目
我淺顯的說一下我的意見
先看手冊怎麼說的：
include&require
include()語句包含並運行指定文件。
HTTP redirects usually have the response status 301 or 302 and provide the redirection URL in the “Location” header. I’ve written three complementary PHP functions that you can use to find out where an URL redirects to (based on a helpful thread at WebmasterWorld). You don’t even need CURL for this – fsockopen() will do just fine.
The PHP script
/**
* get_redirect_url()
* Gets the address that the provided URL redirects to,
* or FALSE if there's no redirect.
*
* @param string $url
* @return string
*/
＜?php
