<h3>Statement Tags</h3>
<p>
-Statement tags are similar to expression tags, except that statement tags contain PHP statements rather than expressions. The output of the PHP statements (using for example <tt>echo</tt> or <tt>print</tt> in PHP) are displayed at the place where the statement tag resides in the template.

<h3>Databind Tags</h3>
<p>
-Databind tags are similar to expression tags, except that the expressions are evaluated only when a <tt>dataBind()</tt> call is invoked on the controls representing the databind tags. Internally, a <tt>TLiteral</tt> control is used to represent a databind tag and <tt>$this</tt> in the expression would refer to the control. The format of databind tags is as follows,
