You got it.

It's tidier to build containers for related data. If I had an array set
containing customer details such as name, email, etc etc, I could
simply session that one post variable (since it is an array). Another
little cheat I sometimes use is casting the array to an object so that
I can avoid typing so many quotes and brackets:
<?php
$a["name"] = "joe";
$a["age"] = "55"];
....
$a = (object) $a;
echo "The person named ",$a->name, " is ",$a->age," years old.";
?>

My editor is snippet based and automatically creates some predefined
attributes such as ID with certain tags. Since I often use javascript
and CSS to help with the look/feel/function of pages, ID attributes
have become something of a necessity over time since they can uniquely
single out nodes.

More recent XHTML standards process code between script tags as PCDATA
( parsed character data ) - which is then evaluated by validators.
Since this is not valid XHTML markup, you would have an invalid page.
Using CDATA sections ( character data ), the markup contained in these
regions is ignored and guarentees that the page is processed properly
by browsers which cannot properly support the XHTML DTD.

Just a style I use depending on what I am doing. Nothing more than
personal preference.
