Solution to the problem of sending emails in php

This article mainly introduces the solution to the problem of sending emails in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

php is used to send emails. The open source project PHPMailer is generally used to implement it. So besides this, are there any other good projects?

Solution:

Use SMTP protocol to send emails

Use its built-in email class in CodeIgniter to send emails

$this->load->library('email');

$to = "aa@bb.cc";
$subject = "test";
$message = "hello!";

$config["protocol"]   = "smtp";
$config["smtp_host"]  = "smtp.163.com";
$config["smtp_user"]  = "username@163.com";
$config["smtp_pass"]  = "password";
$config["mailtype"]   = "html";
$config["validate"]   = true;
$config["priority"]   = 3;
$config["crlf"]     = "/r/n";
$config["smtp_port"]  = 25;
$config["charset"]   = "utf-8";
$config["wordwrap"]   = TRUE;
$this->email->initialize($config);
$this->email->from('xxxx@163.com', 'xxxx');
$this->email->to($to);   
$this->email->subject($subject);
$this->email->message($message); 
$this->email->send();

Send in this way There is no need to install any software for email, but it does require you to write more code and be familiar with SMTP.

But if you don’t write it yourself, but directly use the ready-made code written by others, then this method is undoubtedly the most trouble-free:

There is no need to build an SMTP server yourself, and No need to write a lot of code.

Summary:

Currently, PHP comes with the mail() function based on sendmail to send emails, but the premise is that sendmail must be installed on the server. Many servers The space provider does not have a sendmail mail server installed. So there are certain limitations.

So there are currently many open source components for sending emails based on SMTP. The most famous one is probably phpMailer. You already know this and I won’t go into details. I’ll talk about other methods here.
