Added blank line and now it works?

I’m displaying a list of student names. When they are selected, I want to perform a behavior. I’ve made some changes to the "selectStudent’ behavior and suddenly my list of students stopped working. It reported an error accessing $student->name on line 5 below.

Here’s the original code:

<?php /* @var $student Student */

$student = $enrollment->student;


<div class="view studentNameButton">

&lt;?php echo CHtml::link(CHtml::encode(&#036;student-&gt;fullName), //Here's where the error was reported

	 array('selectStudent','classroomId'=&gt;&#036;classroom-&gt;id, 'studentId'=&gt;&#036;student-&gt;id)); ?&gt;


When I added a blank line before the <div> directive, it suddenly started working. Can anyone explain why? I’m a new user so need all the help I can get.

I’m using:

Yii 1.1.6.r2877

Eclipse Helios Service Release 2

Apache 2.2 server running locally on Windows XP.

remove the blank line again and see what happens?
