What steps can be taken to troubleshoot and resolve issues with PHP scripts not sending emails successfully?

If PHP scripts are not sending emails successfully, one common issue could be misconfigured SMTP settings. To troubleshoot and resolve this issue, ensure that the SMTP server, port, username, and password are correctly set in the PHP script. Additionally, check for any errors in the code that may be preventing the email from being sent successfully. 

// Example PHP script to send email using SMTP

$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";

// Set SMTP settings
$smtpServer = 'smtp.example.com';
$smtpPort = 587;
$smtpUsername = 'your_smtp_username';
$smtpPassword = 'your_smtp_password';

// Create a new PHPMailer instance
$mail = new PHPMailer(true);
$mail->IsSMTP();
$mail->Host = $smtpServer;
$mail->Port = $smtpPort;
$mail->SMTPAuth = true;
$mail->Username = $smtpUsername;
$mail->Password = $smtpPassword;

$mail->setFrom('sender@example.com', 'Sender Name');
$mail->addAddress($to);
$mail->Subject = $subject;
$mail->Body = $message;

if ($mail->send()) {
    echo "Email sent successfully";
} else {
    echo "Email sending failed: " . $mail->ErrorInfo;
}
