Are there any potential risks or drawbacks to using the fopen function to clear the contents of a file in PHP?

Using the `fopen` function to clear the contents of a file in PHP might pose a risk of accidentally deleting the file contents if not handled properly. To safely clear the contents of a file, it is recommended to open the file in "w" mode, which will truncate the file to zero length if it already exists or create a new file if it does not exist. 

$file = 'example.txt';

// Open the file in "w" mode to clear its contents
$handle = fopen($file, 'w');

// Close the file handle
fclose($handle);
