How to Fix the \'Could Not Instantiate Mail Function\' Error in PHPMailer?

Resolving the "Could Not Instantiate Mail Function" Error in PHPMailer

The error "Could not instantiate mail function" in PHPMailer can occur when using the mail() function. Here's a possible solution:

<code class="php">$mail->IsSMTP();
$mail->Host = "smtp.example.com";

// Optional
if the SMTP server requires authentication, uncomment the following lines
$mail->SMTPAuth = true;
$mail->Username = 'smtp_username';
$mail->Password = 'smtp_password';</code>

Explanation:

By default, PHPMailer uses the PHP mail() function to send emails. Changing this to SMTP ensures that a proper SMTP server is used to handle the email transmission, resolving the "mail() function" instantiation error.

The provided code configures SMTP settings such as the host server, and optionally includes authentication credentials if required by the server. This ensures that the PHPMailer object can connect to the SMTP server and send emails successfully.

Remember to replace "smtp.example.com" with the actual SMTP server address, and update the username and password accordingly if authentication is required.
