You have output escaping turned on, so every variable passed to the
template is escaped.
In symfony escaping is done by decorating every variable in an object.
In your case this object is an instance of sfOutputEscaperArrayDecorator
which acts as an array.
An instance of this class acts as an array BUT, in PHP, it only works
under some circonstancies. For example, you are able to use your
decorated array in a foreach() call. Unfortunately, it does not work
with the implode() function.
So, you can do something like this:
<?php echo implode(', ', $mkeywords->getRawValue()) ?>
The problem is that you use the unescaped value here.
You can also use foreach(), but it is a bit more complex:
<?php foreach ($mkeywords as $keyword): ?>
... do something with $keyword ...
<?php endforeach; ?>
