In PHP, should I use fclose() when using file_put_contents()?

Question

I'm using the PHP function file_put_contents() to put some content into a txt file. The example in the docs doesn't finish using fclose(), should I close the file or it's not necessary?

I'm doing this:

        $root = $_SERVER['DOCUMENT_ROOT'];
        $log = $root.'/logs/logsContenido.txt';
        $agregadoLog = "texto a agregar";
        file_put_contents($log, $agregadoLog, FILE_APPEND | LOCK_EX);

And just that. I don't close anything.

Should I rather do something like:

            $root = $_SERVER['DOCUMENT_ROOT'];
            $log = $root.'/logs/logsContenido.txt';
            $agregadoLog = "texto a agregar";
            $file = file_put_contents($log, $agregadoLog, FILE_APPEND | LOCK_EX);
fclose($file);

No, you should not/cannot. file_put_contents takes care of opening the file, writing the contents, and closing the file. In fact it does not expose any handle to you which you could close even if you wanted to.
