Alternate PHP Syntax for View Files

- -

If you do not utilize CodeIgniter's template engine, 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.

- -

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; ?> - - - -
