title: Is this expression right?
body: <pre><code>$tagstring = "search,google,searchengine,engine,web,reference,searchengines,internet,research,tools";
  
  if((!empty($tagstring)) &amp;&amp; ($tagstring &lt; 10)){ //insert to mysql
  
  } //end function
  </code></pre>
  
  <p>my question is will this eliminate <code>empty</code> resutl and do not insert if <code>$tagstring</code> is less than 10</p>
  
  <p>my doubt is do I need to use <code>$tagstring &lt; 10</code> or <code>$tagstring &gt; 10</code> ?? I want minimum 10 or more tags on database</p>
