What are some best practices for handling repetitive data in PHP-generated emails?

When dealing with repetitive data in PHP-generated emails, it's best to use loops to iterate over the data and dynamically generate the content. This allows for a more efficient and scalable solution, as it eliminates the need to manually hardcode each piece of data.

// Sample code demonstrating how to handle repetitive data in PHP-generated emails using a loop

// Sample data
$data = array(
    array('name' => 'John Doe', 'email' => 'john.doe@example.com'),
    array('name' => 'Jane Smith', 'email' => 'jane.smith@example.com'),
    array('name' => 'Tom Brown', 'email' => 'tom.brown@example.com')
);

// Email content template
$emailContent = "Hello,\n\n";
$emailContent .= "Here is a list of users:\n\n";

// Loop through data and add to email content
foreach ($data as $user) {
    $emailContent .= "Name: " . $user['name'] . "\n";
    $emailContent .= "Email: " . $user['email'] . "\n\n";
}

// Send email
$to = 'recipient@example.com';
$subject = 'List of Users';
$headers = 'From: sender@example.com';
mail($to, $subject, $emailContent, $headers);
