What are the potential pitfalls of including function calls within strings in PHP?

Including function calls within strings in PHP can lead to readability issues and make the code harder to maintain. It can also make debugging more challenging, as it may be harder to identify where the function is being called. To solve this issue, it is recommended to separate the function call from the string and concatenate the result of the function with the string. 

// Instead of including function calls within strings
$message = "Hello, " . getName() . "!";

// Separate the function call and concatenate the result with the string
$name = getName();
$message = "Hello, " . $name . "!";
