What are the implications of operating within Safe Mode restrictions when dealing with file operations in PHP scripts?

Operating within Safe Mode restrictions in PHP scripts can limit certain file operations, such as reading or writing files outside the designated directories. To work around this limitation, you can use functions like `file_get_contents()` and `file_put_contents()` that operate within the allowed directories specified in the `open_basedir` directive in the php.ini file.

// Example of reading a file using file_get_contents within Safe Mode restrictions
$file_contents = file_get_contents('allowed_directory/file.txt');
echo $file_contents;

// Example of writing to a file using file_put_contents within Safe Mode restrictions
$data = "Hello, World!";
file_put_contents('allowed_directory/output.txt', $data);
