What are common issues when sending emails through a PHP contact form?

Common issues when sending emails through a PHP contact form include emails not being delivered, emails being marked as spam, and incorrect email formatting. To solve these issues, ensure that the email server settings are correctly configured, use a reputable email service provider, and validate user input to prevent incorrect email formatting. 

// Example of setting up PHPMailer to send emails through a contact form

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

// Include PHPMailer autoload file
require 'vendor/autoload.php';

// Create a new PHPMailer instance
$mail = new PHPMailer();

// Set up the SMTP settings
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'yourpassword';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

// Set email content
$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('to@example.com', 'Recipient Name');
$mail->Subject = 'Subject of the email';
$mail->Body = 'This is the body of the email';

// Send the email
if (!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}
