Checking if your code is running on 64-bit PHP
<p>Does anyone know of a way of checking within PHP if the script is running as either 32-bit or 64-bit?  Currently I'm using PHP 5.3.5.</p>

<p>Ideally I'd like to write a function so my code can look like this:</p>

<pre><code>if( is_32bit() === true ) {
    do_32bit_workaround();
}
do_everything_else();
</code></pre>

<p>Anyone have any thoughts?</p>
