   7  <tt>TStatements</tt> evaluates a sequence of PHP statements and displays the content rendered by the statements. To specify the PHP statements to be evaluated, set the <tt>Statements</tt> property. For example, the following component tag displays the current time on the Web page,
   8  </p>
   9  <com:TTextHighlighter Language="prado" CssClass="source">
  10  &lt;com:TStatements&gt;
  11    &lt;prop:Statements&gt;
  12    setlocale(LC_ALL, 'nl_NL');
  13    echo strftime("%A %e %B %Y",time());
  14    &lt;/prop:Statements&gt;
  15  &lt;/com:TStatements&gt;
  16  </com:TTextHighlighter>
  17  
  18  <p>
  19  Note, <tt>TStatements</tt> evaluates the PHP statements during the rendering control lifecycle. Unlike <tt>TExpression</tt>, <tt>TStatements</tt> only displays the content 'echoed' within the statements.
  20  </p>
  21  
  22  <p>
  23  The context of the statements in a <tt>TStatements</tt> control is the control itself. That is, <tt>$this</tt> represents the control object if it is present in the statements. For example, the following statement tag will display the title of the page containing the <tt>TStatements</tt> control.
  24  </p>
  25  <com:TTextHighlighter Language="prado" CssClass="source">
  26  &lt;com:TStatements&gt;
  27    &lt;prop:Statements&gt;
  28    $page=$this->Page;
  29    echo $page->Title;
  30    &lt;/prop:Statements&gt;
  31  &lt;/com:TStatements&gt;
  32  </com:TTextHighlighter>
  33  
  34  <p>
  35  Be aware, since <tt>TStatements</tt> allows execution of arbitrary PHP code, in general you should not use it to evaluate PHP code submitted by your application users.
