Best way to determine if a file is empty (php)?
<p>I'm including a custom.css file in my template to allow site owners to add their own css rules. However, when I ship the file, its empty and there's no sense loading it if they've not added any rules to it.</p>

<p>What's the best way to determine if its empty?</p>

<pre><code>if ( 0 == filesize( $file_path ) )
{
    // file is empty
}

// OR:

if ( '' == file_get_contents( $file_path ) )
{
    // file is empty
} 
</code></pre>
