What are the best practices for maintaining readability when including function calls within strings in PHP?

To maintain readability when including function calls within strings in PHP, it is recommended to use concatenation instead of directly embedding the function calls. This helps separate the logic from the string content, making the code easier to read and understand. 

// Bad practice - embedding function calls directly in a string
$message = "Hello " . getUserFirstName() . ", welcome to our website.";

// Good practice - using concatenation to separate function calls from string content
$firstName = getUserFirstName();
$message = "Hello " . $firstName . ", welcome to our website.";
