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. - -Automatic Short Tag Support -=========================== - -.. note:: 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 *config/config.php* file. - -Please note that if you do use this feature, if PHP errors are -encountered in your **view files**, the error message and line number -will not be accurately shown. Instead, all errors will be shown as -``eval()`` errors. - -Alternative Echos -================= - -Normally to echo, or print out a variable you would do this:: - - <?php echo $variable; ?> - -With the alternative syntax you can instead do it this way:: - - <?=$variable?> - -Alternative Control Structures -============================== - -Controls structures, like if, for, foreach, and while can be written in -a simplified format as well. Here is an example using ``foreach``:: - - <ul> - - <?php foreach ($todo as $item): ?> - - <li><?=$item?></li> - - <?php endforeach; ?> - - </ul> - -Notice that there are no braces. Instead, the end brace is replaced with -``endforeach``. Each of the control structures listed above has a similar -closing syntax: ``endif``, ``endfor``, ``endforeach``, and ``endwhile`` - -Also notice that instead of using a semicolon after each structure -(except the last one), there is a colon. This is important! - -Here is another example, using ``if``/``elseif``/``else``. Notice the colons:: - - <?php if ($username === 'sally'): ?> - - <h3>Hi Sally</h3> - - <?php elseif ($username === 'joe'): ?> - - <h3>Hi Joe</h3> - - <?php else: ?> - - <h3>Hi unknown user</h3> - - <?php endif; ?>
