-<h1>Alternate PHP Syntax for View Files</h1>
-
-<p>If you do not utilize CodeIgniter's <a href="../libraries/parser.html">template engine</a>, you'll be using pure PHP
-in your View files. To minimize the PHP code in these files, and to make it easier to identify the code blocks it is recommended that you use
-PHPs alternative syntax for control structures and short tag echo statements. If you are not familiar with this syntax, it allows you to eliminate the braces from your code,
-and eliminate "echo" statements.</p>
-
-<h2>Automatic Short Tag Support</h2>
-
-<p><strong>Note:</strong> If you find that the syntax described in this page does not work on your server it might
-be that "short tags" are disabled in your PHP ini file. CodeIgniter will optionally rewrite short tags on-the-fly,
-allowing you to use that syntax even if your server doesn't support it. This feature can be enabled in your
-<dfn>config/config.php</dfn> file.</p>
-
-<p class="important">Please note that if you do use this feature, if PHP errors are encountered
-in your <strong>view files</strong>, the error message and line number will not be accurately shown. Instead, all errors
-will be shown as <kbd>eval()</kbd> errors.</p>
-
-
-<h2>Alternative Echos</h2>
-
-<p>Normally to echo, or print out a variable you would do this:</p>
-
-<code><?php echo $variable; ?></code>
-
-<p>With the alternative syntax you can instead do it this way:</p>
-
-<code><?=$variable?></code>
-
-
-
-<h2>Alternative Control Structures</h2>
-
-<p>Controls structures, like <var>if</var>, <var>for</var>, <var>foreach</var>, and <var>while</var> can be
-written in a simplified format as well. Here is an example using foreach:</p>
-
-<code>
-<ul><br />
-<br />
-<var><?php foreach($todo as $item): ?></var><br />
-<br />
-<li><var><?=$item?></var></li><br />
-<br />
-<var><?php endforeach; ?></var><br />
-<br />
-</ul></code>
-
-<p>Notice that there are no braces. Instead, the end brace is replaced with <var>endforeach</var>.
-Each of the control structures listed above has a similar closing syntax:
-<var>endif</var>, <var>endfor</var>, <var>endforeach</var>, and <var>endwhile</var></p>
-
-<p>Also notice that instead of using a semicolon after each structure (except the last one), there is a colon. This is
-important!</p>
-
-<p>Here is another example, using if/elseif/else. Notice the colons:</p>
-
-
-<code><var><?php if ($username == 'sally'): ?></var><br />
-<br />
- <h3>Hi Sally</h3><br />
-<br />
-<var><?php elseif ($username == 'joe'): ?></var><br />
-<br />
- <h3>Hi Joe</h3><br />
-<br />
-<var><?php else: ?></var><br />
-<br />
- <h3>Hi unknown user</h3><br />
-<br />
-<var><?php endif; ?></var></code>
