Are there any best practices for formatting variables within echo statements in PHP?

When formatting variables within echo statements in PHP, it is best practice to enclose the variables within curly braces for better readability and to avoid potential parsing issues. This ensures that the variable is clearly separated from surrounding text and improves code maintainability.

// Example of formatting variables within echo statements using curly braces
$name = "John";
echo "Hello, {$name}!";
