How can PHP developers ensure proper cleanup and deletion of temporary files after including and executing code?

PHP developers can ensure proper cleanup and deletion of temporary files by using the `tempnam()` function to create a unique temporary file, including and executing the code within that file, and then using `unlink()` to delete the temporary file after the code has been executed. 

$tempFile = tempnam(sys_get_temp_dir(), 'prefix');
file_put_contents($tempFile, $codeToExecute);

include $tempFile;

unlink($tempFile);
