Alternate PHP Syntax for View Files

+ +

If you do not utilize Code Igniter'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 echo statements. If you are not familiar with this syntax, it allows you to eliminate the braces from your code, +and eliminate "echo" statements.

+ +

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?> + +

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.

+ + +

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; ?> + + + +
