What potential issues may arise when using file_get_contents to retrieve the content of an HTML template for email purposes in PHP?

One potential issue that may arise when using file_get_contents to retrieve the content of an HTML template for email purposes in PHP is that it may not handle errors gracefully, such as when the file does not exist or cannot be accessed. To solve this, you can use error handling to catch any potential issues and handle them appropriately.

$template_path = 'path/to/your/template.html';

// Check if the file exists before attempting to retrieve its contents
if (file_exists($template_path)) {
    $template_content = file_get_contents($template_path);
    // Use the template content for email purposes
} else {
    echo 'Template file does not exist or cannot be accessed.';
}
