How to control the incoming mails details in php

In PHP, you can control the incoming mail details using various functions and settings. Here are some ways to do so:

mail() function: The mail() function is used to send an email. You can specify the sender's email address, recipient's email address, subject, and message body. For example:
```
mail('[email protected]', 'Subject', 'Hello, this is a test email');
```
headers parameter: You can specify additional headers using the headers parameter of the mail() function. For example:
```
mail('[email protected]', 'Subject', 'Hello, this is a test email', 'From: [email protected]');
```

From header: You can set the From header using the From parameter of the mail() function. For example:

mail('[email protected]', 'Subject', 'Hello, this is a test email', 'From: [email protected]');

Reply-To header: You can set the Reply-To header using the Reply-To parameter of the mail() function. For example:
```
mail('[email protected]', 'Subject', 'Hello, this is a test email', 'Reply-To: [email protected]');
```

CC and BCC headers: You can set the CC and BCC headers using the CC and BCC parameters of the mail() function. For example:

mail('[email protected]', 'Subject', 'Hello, this is a test email', 'CC: [email protected]', 'BCC: [email protected]');

Content-Type header: You can set the Content-Type header using the Content-Type parameter of the mail() function. For example:
```
mail('[email protected]', 'Subject', 'Hello, this is a test email', 'Content-Type: text/html');
```
boundary parameter: You can set the boundary parameter of the mail() function to specify a boundary for multipart emails. For example:
```
mail('[email protected]', 'Subject', 'Hello, this is a test email', 'boundary="----boundary----"');
```

PHPMailer library: You can use the PHPMailer library to send emails with more advanced features, such as attachments, HTML emails, and more. For example:

require_once 'PHPMailer/PHPMailer.php';
$mail = new PHPMailer();
$mail->setFrom('[email protected]');
$mail->addAddress('[email protected]');
$mail->Subject = 'Subject';
$mail->Body = 'Hello, this is a test email';
$mail->send();

SwiftMailer library: You can use the SwiftMailer library to send emails with more advanced features, such as attachments, HTML emails, and more. For example:

require_once 'SwiftMailer/Swift.php';
$mail = new Swift_Mailer();
$mail->setFrom('[email protected]');
$mail->addAddress('[email protected]');
$mail->Subject = 'Subject';
$mail->Body = 'Hello, this is a test email';
$mail->send();

filter_var() function: You can use the filter_var() function to validate and sanitize the email address before sending the email. For example:
```
$email = '[email protected]';
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
 echo 'Invalid email address';
} else {
 mail($email, 'Subject', 'Hello, this is a test email');
}
```
These are some of the ways you can control the incoming mail details in PHP.
