"Building a Web Site with Ajax: Visual QuickProject Guide"
In this script, I??™m making
use of the PECL JSON class
(which must be installed; see
http://pecl.php.net??”it??™s
enabled by default as of PHP
5.2).
??? Alternatively, see the o?¬? cial
JSON Web site (www.json.org)
for includable PHP libraries that
can perform the conversion of an
array to JSON.
146 Appendix
JavaScript frameworks p. 140
??? There are three main downsides
to using frameworks. The fi rst is
that they require some effort to
learn how to use them. The second
is that they normally greatly
increase the amount of data
that a user must download from
your site (which is to say, frameworks
are almost inherently
bloated). Finally, you must pay
attention to new releases of a
framework, as they might patch
security holes.
??? In choosing a framework, factor
in how many and what browsers
it supports, how large it is
(in terms of fi le size that the user
will end up downloading), and
how well documentated it is.
