title: Using meta tags with PHP for search engines
body: <p>I have a site and there are more than 100 folders and files. For search engines,meta tags are very important. So,instead of using meta tag as html like :</p>
  
  <pre><code>    &lt;meta name="keywords" content="html,php,seo" /&gt; 
  </code></pre>
  
  <p>can I use this with PHP like:</p>
  
  <pre><code>   &lt;?php 
     $sql ="SELECT keywords FROM database";
     $result = mysql_query($sql);
      while ($row=mysql_fetch_array($result)) {
     echo "&lt;meta name='keywords' content='{$row['keywords']}' /&gt;" . ",";
  </code></pre>
  
  <p>For search engines, are both codes same to be indexed?</p>
