Php mail function debugging

Отладка PHP Mail () и / или PHPMailer

Я довольно застрял в проблеме отправки почты с PHP-скрипта. Некоторые данные:

• Общий хостинг, отсутствие доступа к SSH, только панель поставщика хостинга
• PHP версия 5.2.5
• В прошлом году я построил сайт, у которого не было проблем с отправкой почты с тем же хостингом
• Предположим, что домен «domain.com», а мой частный адрес – «myaddress@mydomain.com» для анонимности в следующем коде.

php error_reporting(E_ALL); ini_set("display_errors", 1); $to = "myaddress@mydomain.com"; $subject = "Hi"; $body = "Test 1\nTest 2\nTest 3"; $headers = 'From: info@domain.com' . "\r\n" . 'errors-to: myaddress@mydomain.com' . "\r\n" . 'X-Mailer: PHP/' . phpversion(); if (mail($to, $subject, $body, $headers)) < echo("Message successfully sent"); >else < echo("Message sending failed"); >require('class.phpmailer.php'); $message = "Hello world"; $mail = new PHPMailer(); $mail->CharSet = "UTF-8"; $mail->AddAddress("myaddress@mydomain.com", "Agos"); $mail->SetFrom("info@domain.com","My Site"); $mail->Subject = "Test Message"; $mail->Body = $message; $mail->Send(); ?> 

Ошибка отправки сообщения Не удалось создать почтовую функцию.

Это, по меньшей мере, озадачивает. Есть ли что-нибудь, что я могу сделать, чтобы получить хотя бы более значимые ошибки? Почему код из класса отображается в моем файле?

Похоже, файл class.phpmailer.php поврежден. Я бы загрузил последнюю версию и повторил попытку.

Я всегда использовал SMTP-функцию phpMailer:

$mail->IsSMTP(); $mail->Host = "localhost"; 

И если вам нужна информация об отладке:

$mail->SMTPDebug = 2; // enables SMTP debug information (for testing) // 1 = errors and messages // 2 = messages only

Debugging PHP Mail() and/or PHPMailer

When it comes to sending emails with PHP, the `mail()` function and PHPMailer are two popular options. However, errors can occur when trying to send emails through either of these methods. In this guide, we will go over some common issues that may cause problems with sending emails through PHP’s `mail()` function or PHPMailer and how to debug them.

Debugging PHP’s mail() Function

The `mail()` function is a built-in PHP function that sends email. Here are some common issues and how to debug them:

SMTP Server Configuration

If the email is not being delivered, the first thing to check is the SMTP server configuration. Make sure the SMTP server information is correct and that the server is running. You can check this by using the `telnet` command to connect to the SMTP server.

// Example of SMTP server configuration ini_set("SMTP","smtp.example.com"); ini_set("smtp_port","25"); 

Email Headers

The email headers can also cause issues. Make sure the `From` header is set correctly and that it includes a valid email address. Additionally, make sure the `To` header is set to a valid email address.

// Example of email headers $headers = "From: sender@example.com"; $headers .= "Reply-To: sender@example.com"; $headers .= "Content-type: text/html; charset=iso-8859-1"; 

Email Content

If the email is not being sent, make sure the email content is correct. Check that the email body is not empty and that any HTML markup is valid.

// Example of email content $subject = "Example Subject"; $message = "This is an example email message."; 

Error Reporting

Finally, turn on error reporting to help identify any issues. This can be done by adding the following line of code at the beginning of your PHP script.

// Turn on error reporting error_reporting(E_ALL); 

Debugging PHPMailer

PHPMailer is a popular third-party library used to send emails in PHP. Here are some common issues and how to debug them:

SMTP Server Configuration

Just like with the `mail()` function, the SMTP server configuration is critical when using PHPMailer. Make sure the SMTP server information is correct and that the server is running.

// Example of SMTP server configuration with PHPMailer $mail = new PHPMailer; $mail->isSMTP(); $mail->Host = 'smtp.example.com'; $mail->SMTPAuth = true; $mail->Username = 'user@example.com'; $mail->Password = 'password'; $mail->SMTPSecure = 'tls'; $mail->Port = 587; 

Email Headers

The email headers can also cause issues with PHPMailer. Make sure the `From` header is set correctly and that it includes a valid email address. Additionally, make sure the `To` header is set to a valid email address.

// Example of email headers with PHPMailer $mail->setFrom('sender@example.com', 'Sender Name'); $mail->addAddress('recipient@example.com', 'Recipient Name'); $mail->addReplyTo('sender@example.com', 'Sender Name'); $mail->isHTML(true); $mail->Subject = 'Example Subject'; $mail->Body = 'This is an example email message.'; 

Error Reporting

As with the `mail()` function, turning on error reporting can help identify any issues with PHPMailer. This can be done by adding the following line of code at the beginning of your PHP script.

// Turn on error reporting with PHPMailer $mail->SMTPDebug = SMTP::DEBUG_SERVER; 

Conclusion

Debugging email sending issues in PHP can be challenging, but with the right tools and knowledge, you can solve the problem quickly. Remember to check your SMTP server configuration, email headers, email content, and turn on error reporting to help identify any issues.

How to Debug and Fix PHP Mail in Localhost

Sending emails in your local environment using PHP’s mail() function should be straightforward. The function is 20-years-old and one of the most integral parts of any web application; email.

If you’re not familiar with mail() , it’s a single function that only requires three arguments—a recipient, subject, and message—to deliver an email via one line of code. Sounds simple, right?

Well, if you’ve actually tried to use the function in your local environment, you know firsthand that it’s not always that easy. You’re probably reading this tutorial because you’ve experienced the mail() function not working out of the box yourself. Maybe you’re even one of the 343K viewers of this unresolved, 5-year-old Stack Overflow ticket.

So why isn’t my PHP mail function sending any mail?

The truth is, there could be a number of reasons why your emails aren’t arriving in inboxes. However, I’ve found that most of those reasons are related to Postfix not being configured properly. Postfix is a fast, secure, open-source mail transfer agent that routes and delivers emails. Postfix follows the SMTP protocol and runs on virtually every Unix-like operating system, including macOS.

Because of its wide adoption, Postfix actually comes pre-installed on most non-Windows based computers. So why isn’t your PHP mail function working? It’s most likely because Postfix isn’t configured.

How do you configure Postfix?

Our test to see if Postfix is configured correctly actually begins with testing to see if it’s installed. In your terminal, run the following command:

Any errors outputted during this time may provide some insight as to what’s not working. However, if you get a response that indicates it’s installed, move on to the next section. If it hasn’t been installed, check out the Postfix documentation or contact your host for installation instructions.

Postfix has some minimum requirements that must be met before emails will send correctly.

The first thing you need to do is modify your local Postfix configuration. You can load an editor directly from your terminal by running the following command:

Once open, you’re going to check to make sure that the following 4 variables are defined as follows:

mail_owner=_postfix setgid_group=_postdrop myhostname=localhost.localdomain compatibility_level = 2 

That’s it! Save these changes and restart Postfix using sudo postfix reload .

NOTE: In my experience, the most important of these variables is myhostname . Without this variable being set, your local environment cannot assign a default location to send the email from. This value can be a real domain or something arbitrary just as in the example above.

Testing Postfix and PHP mail()

To test that Postfix is working and subsequently PHP mail() , let’s create a simple script to run. In your favorite integrated development environment (IDE), create a file called mail.php and add the following code:

Be sure to replace the $to variable with your actual email address. In your terminal, run the program using the following command and check your email:

Additional Troubleshooting

If you’ve tested Postfix and your PHP mail() function still isn’t sending mail, here are a few other issues to consider:

• Missing required parameters (Check the official PHP mail documentation to verify.)
• Typos with your recipient email address
• Needing to set up an SMTP relay (This guide can help you set up Postfix to use SendGrid as a relay host.)

Conclusion

Now that you have completed this tutorial, you have the knowledge of setting up Postfix, the inconsistencies of mail() , and how to write a simple email script to send a test email in PHP.
