How to know which php file is sending mails

There are a few ways to determine which PHP file is sending emails:

1. Check the PHP error logs: Most web servers have error logs that record PHP errors, including those related to email sending. You can check the error logs to see if there are any errors related to email sending, and the PHP file that's causing the error should be listed.
2. Use a PHP debugger: A PHP debugger can help you step through your code and see which file is sending the email. Some popular PHP debuggers include Xdebug, Zend Debugger, and PHPStorm.
3. Use a logging library: You can use a logging library like Monolog or Log4PHP to log information about email sending, including the PHP file that's sending the email.
4. Check the email headers: When an email is sent, the email headers contain information about the sender, including the PHP file that's sending the email. You can check the email headers to see which PHP file is sending the email.
5. Use a PHP profiler: A PHP profiler can help you identify which PHP files are taking the most time to execute, which can help you identify which file is sending the email.
6. Check the PHP code: You can manually search through your PHP code to find the files that are sending emails. Look for functions like mail(), sendmail(), or SwiftMailer that are commonly used for sending emails.
7. Use a PHP IDE: Many PHP IDEs, such as PHPStorm, have built-in features that allow you to debug and profile your code, which can help you identify which PHP file is sending the email.

Some common PHP files that send emails include:

• contact.php: This file is often used to send contact form submissions to the website administrator.
• forgot_password.php: This file is often used to send password reset emails to users.
• newsletter.php: This file is often used to send newsletters to subscribers.
• registration.php: This file is often used to send confirmation emails to new users.

Keep in mind that these are just a few examples, and there may be other PHP files that send emails depending on your specific use case.
