PHPMailer Not Found: Resolving the Class Not Found Error

When attempting to use PHPMailer, you may encounter the error message "Fatal error: Class 'PHPMailer' not found." This issue arises when the PHPMailer library is not properly included in your script.

require("path/to/SMTP.php");

2. Initialize the PHPMailer object:

$mail = new PHPMailer\PHPMailer\PHPMailer();

3. Configure the SMTP settings and other properties:

$mail->IsSMTP();
$mail->SMTPDebug = 1;
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'ssl';
$mail->Host = "smtp.gmail.com";
$mail->Port = 465;
$mail->IsHTML(true);
$mail->Username = "your-email";
$mail->Password = "your-password";
$mail->SetFrom("from@email.com");
$mail->Subject = "Subject";
$mail->Body = "Message";
$mail->AddAddress("to@email.com");

4. Send the email:

if(!$mail->Send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message has been sent";
}
