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> - - - -</div> -<!-- END CONTENT --> - - -<div id="footer"> -<p> -Previous Topic: <a href="managing_apps.html">Managing Applications</a> - · -<a href="#top">Top of Page</a> · -<a href="../index.html">User Guide Home</a> · -Next Topic: <a href="security.html">Security</a> -</p> -<p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006 - 2011 · <a href="http://ellislab.com/">EllisLab, Inc.</a></p> -</div> - -</body> -</html>
