Brief introduction to ThinkPhp email sending class

In thinkphp learning, there are often many problems. mailbox sending problems will be used and involved continuously during the development of large websites. below we will talk about the two email sending mechanisms.

Thinkphp often encounters many problems, which are used and involved continuously during large-scale website development;

Let's talk about the two email sending mechanisms below:

1. intra-site email sending mechanism: it is not hard to understand that email sending is performed on the same site, that is, the email communication function of registered members on a website, this is very common in the development of leisure time to discuss more, his mechanism is simple and indeed a bit complex, but compared to the following relatively simple:

Communication between two users in the station, of course, you must first establish the mail data used by the user to send emails. to put it simply: Since communication is between users, you must have a user name or a user nickname. this is required. even if you do not want the recipient to see who the sender is, you must create an email subject, the content of the email and the content of the email attachment (this can be left blank for the time being)

You must use these two or three fields to store data. Also, you need an independent field to check whether new emails are unread, this field is saved in 1, 2 (for example). when a new email is sent, Data 1 is filled in this field by default. it is convenient to update the field to 2 after the user has watched it.

When a user sends an email to another user, the fields in the table of another user are filled with the title, content, and fields to determine whether or not the fields are read.

Update data fields when another user reads data.

This is the first form of intra-site text message sending, which is troublesome and easy to write code.

Type 2: Send Mail pop3 stmp = through the mail protocol

The source code is attached to Tom here,

Class MessageAction extends Action {
Public function mail () {// mail method definition
$ Response = trim ($ _ POST ['comment']); // the comment string sent by the user through form POST.
If ($ response = ")

}
