What are the best practices for handling safe mode restrictions in PHP when uploading files?

When uploading files in PHP, it is important to consider safe mode restrictions that may limit file operations. To handle this, you can check if safe mode is enabled and adjust your file handling accordingly. One approach is to use the `ini_get()` function to check the value of the `safe_mode` directive and then use alternative methods like `move_uploaded_file()` or `copy()` to handle file uploads securely. 

// Check if safe mode is enabled
if(ini_get('safe_mode')){
    // Use alternative file handling methods
    if(move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name'])){
        echo 'File uploaded successfully';
    } else {
        echo 'Failed to upload file';
    }
} else {
    // Use regular file handling methods
    if(move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name'])){
        echo 'File uploaded successfully';
    } else {
        echo 'Failed to upload file';
    }
}
