Separate text with a number as separator
<p>I have text like <code>"My Cart n items"</code> (e.g. <code>"My Cart 2 items"</code>).</p>

<p>I want to separate it into two PHP variables, such that the first is like <code>"My Cart"</code> and the second like <code>"2 items"</code>.</p>

<p>How can I do this?</p>
