remove numbers from string elegant solution
<p>I'd like to remove all numbers from a string [0-9]. I wrote this code that is working:</p>

<pre><code>$words = preg_replace('/0/', '', $words ); // remove numbers
$words = preg_replace('/1/', '', $words ); // remove numbers
$words = preg_replace('/2/', '', $words ); // remove numbers
$words = preg_replace('/3/', '', $words ); // remove numbers
$words = preg_replace('/4/', '', $words ); // remove numbers
$words = preg_replace('/5/', '', $words ); // remove numbers
$words = preg_replace('/6/', '', $words ); // remove numbers
$words = preg_replace('/7/', '', $words ); // remove numbers
$words = preg_replace('/8/', '', $words ); // remove numbers
$words = preg_replace('/9/', '', $words ); // remove numbers
</code></pre>

<p>I'd like to find a more elegant solution: 1 line code (IMO write nice code is important!). </p>

<p>The other code I found in stackoverflow also remove the Diacritics (á,ñ,ž...).</p>
