How to use PHP to connect the mail class to realize the marking and filtering functions of mail?

With the popularity and widespread use of email, as well as the growing number of emails, how to efficiently manage and filter emails has become a concern for many people. As a very popular server-side scripting language, PHP provides powerful tools and libraries to process emails, which can help us implement email marking and filtering functions.

Before we begin, we need to ensure that the PHP mail extension has been installed and configured correctly. You can check if the mail extension exists with the following code.

Next, we need to use PHP’s core class library for email processing, such as PHPMailer or SwiftMailer. Here we take PHPMailer as an example for demonstration. You can install PHPMailer through composer:

composer require phpmailer/phpmailer

After the installation is complete, introduce the PHPMailer class library into the code:

Next, we can use PHP's IMAP extension to connect to the mailbox server, Get the list and details of the message. The following code example demonstrates how to connect to a Gmail mailbox and obtain a mailing list:

isIMAP();

// 邮箱配置
$mail->Host = 'imap.gmail.com';
$mail->Port = 993;
$mail->IMAPSecure = 'ssl';
$mail->Username = 'your-email@gmail.com';
$mail->Password = 'your-password';

// 连接服务器
$mail->imapConnect();

// 获取未读邮件列表
$mail->imapSearch('UNSEEN');

// 遍历邮件列表
$emails = $mail->getImapSearchResults();
foreach ($emails as $email) {
    echo 'Subject: ' . $email->subject . '
';
    echo 'From: ' . $email->from . '
';
    echo 'Date: ' . $email->date . '

';
}
?>

In the above code, we first set the use of the IMAP protocol through the $mail->isIMAP() method . Then configure the server address, port, username and password of the mailbox. Next, connect to the mailbox server through the $mail->imapConnect() method. Finally, we use the $mail->imapSearch('UNSEEN') method to get the unread mail list, iterate through the list and output the subject, sender and date of the mail.

After obtaining the mailing list, we can also mark and filter the mails. The following code example demonstrates how to mark and filter emails:

imapMarkAsRead($email->uid);

// 标记邮件为未读
$mail->imapMarkAsUnread($email->uid);

// 删除邮件
$mail->imapDelete($email->uid);

// 创建文件夹
$mail->imapCreateFolder('MyFolder');

// 移动邮件到指定文件夹
$mail->imapMoveToFolder($email->uid, 'MyFolder');

// 永久删除邮件
$mail->imapPermanentlyDelete($email->uid);
?>

In the above code, we mark the email as has been done by $mail->imapMarkAsRead($email->uid) Read, via $mail->imapMarkAsUnread($email->uid) Mark the email as unread, via $mail->imapDelete($email->uid)Delete emails via $mail->imapCreateFolder('MyFolder')Create a folder via $mail->imapMoveToFolder($email->uid, 'MyFolder')Move the email to the specified folder and permanently delete the email through $mail->imapPermanentlyDelete($email->uid).

By using PHP to connect email classes, we can easily implement the marking and filtering functions of emails. The above code examples provide a basic framework that you can further develop and customize according to your needs. I hope this article can help you better use PHP to process emails.
