PHP email sending methods and summary of frequently asked questions
In the Internet era, email has become an indispensable part of people's lives and work. PHP is a language widely used in the field of web development, and email sending is also essential in web applications. This article will introduce in detail the relevant content and common problems of PHP email sending.
1. PHP email sending method
- PHPmailer library
PHPmailer is a powerful PHP email sending library that can easily send Emails in HTML format and plain text format. Using PHPmailer can avoid the problem of email sending failure caused by the limitations of PHP's native email sending function.
To use the PHPmailer library to send emails, you need to first download the source code package of the PHPmailer library and extract it to the root directory of the website. Then, include the library file, instantiate the PHPmailer object, set the email parameters, and finally call the send() method.
The following is a sample code for sending emails using the PHPmailer library:
require_once 'phpmailer/PHPMailerAutoload.php'; //包含类库文件 $mail = new PHPMailer; $mail->isSMTP(); //使用SMTP方式发送邮件 $mail->SMTPAuth = true; //开启SMTP认证 $mail->Host = 'smtp.gmail.com'; //SMTP服务器地址,例如:smtp.gmail.com $mail->Username = 'username@gmail.com'; //SMTP服务器用户名,例如:username@gmail.com $mail->Password = 'password'; //SMTP服务器密码,例如:password $mail->SMTPSecure = 'ssl'; //开启SMTP使用的SSL协议,一般使用ssl或tls $mail->Port = 465; //SMTP服务器端口号,例如:465 $mail->setFrom('from@example.com', 'Sender'); //设置发件人邮箱地址和名称 $mail->addAddress('to@example.com', 'Recipient'); //设置收件人邮箱地址和名称 $mail->isHTML(true); //设置邮件正文为HTML格式 $mail->Subject = 'Subject'; //设置邮件标题 $mail->Body = 'Mail Content'; //设置邮件正文 $mail->AltBody = 'Text Content'; //设置纯文本格式的邮件正文 if(!$mail->send()) { echo 'Mail could not be sent. Error: ' . $mail->ErrorInfo; } else { echo 'Mail has been sent.'; }
- PHP built-in function mail()
PHP built-in function mail() is the most Simple, straightforward way to send emails. To send an email using this method, just pass in the email parameters when calling the function. However, due to limitations of PHP, the mail() function may fail to send. For example, the email may be automatically judged as spam by the server and rejected.
The following is a sample code for sending emails using PHP's built-in function mail():
$to = 'to@example.com'; //收件人邮箱地址 $subject = 'Subject'; //邮件标题 $message = 'Mail Content'; //邮件正文 $from = 'Sender <from@example.com>'; //发件人名称和邮箱地址 $headers = "From: " . $from . " "; //设置邮件头部信息,包括发件人姓名和邮箱地址 $headers .= "Reply-To: ". $from . " "; //设置收件人回复的邮箱地址 $headers .= "MIME-Version: 1.0 "; //设置邮件头部为MIME类型 $headers .= "Content-type:text/html;charset=UTF-8 "; //设置邮件正文为HTML类型 if(mail($to, $subject, $message, $headers)){ //调用mail()发送邮件 echo 'Mail has been sent.'; }else{ echo 'Mail could not be sent.'; }
2. Common problems and solutions for sending PHP emails
- Chinese garbled emails
When the email contains Chinese characters, the email content may be garbled. At this time, you can set the encoding method of the email so that the email can display Chinese correctly. You can add the following content in the header information of the email:
$headers .= "Content-Type:text/html;charset=UTF-8 "; //设置邮件正文编码为UTF-8 $headers .= "Content-Transfer-Encoding: base64 "; //设置邮件正文编码方式为base64
- Failed to send the email
The failure to send the email may be due to the following reasons: The mail server port setting is incorrect Correct, the email account or authorization code is wrong, etc. You can try to use other email accounts or modify parameters such as the email server address and port to solve the problem of email sending failure.
- The email is identified as spam
When the email content or header information contains certain keywords or symbols, the email may be automatically identified as spam by the server The email was returned. You can try to remove sensitive words or symbols from the email content, or add the email sending address to the whitelist of your mailbox.
- Style is missing
When sending an email in HTML format, the style in the email body may be lost in some mailboxes, causing the email to display abnormally. At this time, you can try to use inline styles or attached style sheets to style the email body.
- The mailbox capacity is not enough
When the mailbox capacity is full and no more new mails can be received, mail sending will also fail. You can solve this problem by clearing out unnecessary emails or purchasing a larger mailbox.
Summary:
Email sending can be said to be one of the regular operations in web applications. This article introduces common email sending methods and their usage in PHP, and also solves common email sending problems. I hope this article can help you better implement the email sending function.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
