What are some best practices for combining static content with dynamic data output in PHP loops?

When combining static content with dynamic data output in PHP loops, it's important to properly concatenate the static content with the dynamic data within the loop to ensure the output is correctly formatted. One way to achieve this is by using string concatenation operators like the dot (.) in PHP to combine the static content and dynamic data together.

// Example of combining static content with dynamic data output in a PHP loop
$names = ['Alice', 'Bob', 'Charlie'];

foreach ($names as $name) {
    echo 'Hello, ' . $name . '!<br>';
}
