Do many here use the SPL library?
I know zend framework uses a bunch of it. Zend_Registry, for
example, extends from ArrayObject. The DirectoryIterator seems kinda
convenient. I haven't gotten that into it yet though.
I could never really understand this "library", on one side part of
the Java programming that I really felt to be a burden of added /
bloated code was the idea of the "Iterator" (you always had to grab
one) and that is pretty much what the SPL is (for PHP5), and part
of the joy to PHP was the ease + use of a foreach loop and then
Java took a step back and implemented the same foreach idea in
current JVMs but I barely see it used in many projects. I would
guess that Java people coming to PHP would understand it's uses /
design pattern better but the part of the Zend article I don't
understand is ...
"This library of interfaces creates a standard API for certain
kinds of built-in functionality, allowing your classes to interact
with the PHP engine in a much more seamless manner."
Im just wondering if this means the use of saying "foreach($objects
as $object)" or does refactoring w/ PHP5 Iterators also get you
something else as well?
I think there are more built-in php functions that your objects can
take advantage of... found this in the unit test code, for example:
<?php
$ar = array(0=>0, 1=>1);
$ar = new ArrayObject($ar);
var_dump($ar);
$ar[2] = 2;
var_dump($ar[2]);
var_dump($ar["3"] = 3);
var_dump(array_merge((array)$ar, array(4=>4, 5=>5)));
?>
On a side note, the initial reaction of a of mine friend to the zend
framework was that it felt too much like java. He's a former java
developer, who switched to php, and now works in ruby as well).
