$mail->SMTPAuth = true;
$mail->Host = 'smtp.gmail.com';
$mail->Username = 'your_gmail_username@gmail.com';
$mail->Password = 'your_gmail_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587; // Define recipient, subject, and message
$mail->setFrom('your_email@example.com');
$mail->addAddress('recipient@example.com');
$mail->Subject = 'Test Email';
$mail->Body = 'This is a test email message.'; // Send the email
if (!$mail->send()) {
echo 'Message could not be sent. '
.'Mailer Error: '.$mail->ErrorInfo;
} else {
echo 'Message has been sent.';
}

With the above steps, you can easily set up SMTP and Gmail for email sending in PHP. However, before sending any emails, ensure that you have verified your Gmail account and have enabled the ‘Less secure app access’ setting in your account security.

Creating a PHP Function for Email Sending

Creating a custom PHP function for email sending can simplify your code and make it more organized. It allows you to reuse the same code over and over again in different parts of your application, saving you a lot of time and effort.

Here is a sample code template for a basic function that sends emails:

Function: send_email($to, $subject, $message)
{
$headers = ‘From: John Doe <john.doe@example.com>’ . “\r\n” .
‘Reply-To: john.doe@example.com’ . “\r\n” .
‘MIME-Version: 1.0’ . “\r\n” .
‘Content-Type: text/html; charset=ISO-8859–1’ . “\r\n” .
return mail($to, $subject, $message, $headers);
}

The function accepts three parameters:

1. $to: The email address of the recipient.
2. $subject: The subject of the email.
3. $message: The message content of the email.

The function returns a boolean value, indicating whether the email was sent successfully or not.

You can customize the $headers variable according to your needs, such as adding a CC or BCC recipient, adding attachments, or setting a custom email sender name.

Using a custom PHP function for email sending can greatly simplify your code and make it more efficient. It allows you to centralize your email sending logic into a single function and reuse it across your application without duplicating code.

Advanced Options for Email Sending in PHP
