How does Safe Mode in PHP impact directory creation and file uploads?

Safe Mode in PHP restricts the permissions for file operations, including directory creation and file uploads. To work around this limitation, you can use alternative methods such as using the `mkdir()` function with appropriate permissions or utilizing external libraries like `move_uploaded_file()` for file uploads. Additionally, you can check for the safe mode status using the `ini_get()` function and adjust your code accordingly.

// Check if safe mode is enabled
if(ini_get('safe_mode')){
    // Use alternative methods for directory creation and file uploads
    mkdir('uploads', 0755);
    move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name']);
} else {
    // Use standard methods
    mkdir('uploads');
    move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name']);
}
