What considerations should be made when sending error summaries via email in PHP after executing multiple methods?

When sending error summaries via email in PHP after executing multiple methods, it is important to ensure that the email is clear and concise, providing all relevant information about the errors that occurred. Consider including details such as the method that caused the error, the type of error, and any relevant context or variables. Additionally, make sure to handle any potential errors that may arise during the email sending process to prevent further issues.

// Example code snippet for sending error summaries via email in PHP

// Define error message
$error_message = "An error occurred in method XYZ: Undefined variable 'foo'";

// Define recipient email address
$to = "recipient@example.com";

// Define email subject
$subject = "Error Summary";

// Send email with error message
if (mail($to, $subject, $error_message)) {
    echo "Error summary sent successfully";
} else {
    echo "Error sending error summary";
}
