What are the potential pitfalls of using eval in PHP, and are there alternative approaches to achieve similar functionality?

Using eval in PHP can be dangerous as it allows for the execution of arbitrary code, which can lead to security vulnerabilities if not properly sanitized. An alternative approach to achieve similar functionality is to use built-in PHP functions like `include` or `require` to dynamically load and execute code from external files. 

// Using include to dynamically load and execute code from an external file
$filename = 'somefile.php';
if (file_exists($filename)) {
    include $filename;
} else {
    echo 'File not found';
}
