title: How to put more than one specicfication after the WHERE part when selecting data in php pdo
body: <p>I am creating a website that takes data from the user and searches in some  database for a hall that meets all the users specifications so I search in the database using php pdo method by typing </p>
  
  <p><code>(SELECT * FROM thetablename WHERE place=$place,category=$category)</code></p>
