title: WordPress prepared statement with IN() condition
body: <p>I have three values in a string like this:</p>
  <pre><code>$villes = '&quot;paris&quot;,&quot;fes&quot;,&quot;rabat&quot;';
  </code></pre>
  <p>When I feed it into a prepared statement like this:</p>
  <pre><code>$sql    = 'SELECT distinct telecopie FROM `comptage_fax` WHERE `ville` IN(%s)';
  $query  = $wpdb-&gt;prepare($sql, $villes);
  </code></pre>
  <p><code>echo $query;</code> shows:</p>
  <pre><code>SELECT distinct telecopie FROM `comptage_fax` WHERE `ville` IN('\&quot;CHAPELLE VIVIERS \&quot;,\&quot;LE MANS \&quot;,\&quot;QUEND\&quot;')
  </code></pre>
  <p>It is not writing the string as three separate values -- it is just one string with the double quotes escaped.</p>
  <p>How can I properly implement a prepared statement in WordPress with multiple  values?</p>
