What are the potential pitfalls of dynamically calling functions in PHP?

One potential pitfall of dynamically calling functions in PHP is the lack of error checking. If the function being called dynamically does not exist, it can result in a fatal error. To avoid this issue, you can use the function_exists() function to check if the function exists before calling it dynamically. 

// Check if the function exists before dynamically calling it
if (function_exists($functionName)) {
    $functionName();
} else {
    echo "Function does not exist.";
}
