What steps should be taken if the "undefined function: mail()" error occurs on a local server?

The "undefined function: mail()" error occurs when the mail function is not enabled in the PHP configuration on the local server. To solve this issue, you need to enable the mail function by configuring the php.ini file to include the SMTP settings of your email server. 

// Configure the SMTP settings in php.ini file
ini_set("SMTP", "mail.example.com");
ini_set("smtp_port", "25");

// Send an email using the mail function
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: sender@example.com";

mail($to, $subject, $message, $headers);
