I've been reworking the ModelForm class for ZF a bit. Earlier this year, I discussed porting it to use Zend_Db_Table with Matthew Weier O'Phinney, for using it with Zend Framework. I initially had done some checking on Zend_Db_Table, and some small code changes to modify the class to use it ...

I've heard some inexperienced PHP programmers say that Zend Framework is confusing to them.

This seems to be a relatively common question on #zftalk nowadays, so here's a quick wrapup!
The traditional plain-PHP way
$file = file_get_contents('some.zip');
header('Content-Type: application/zip');
header('Content-Disposition: attachment; filename="some.zip"');

echo $file;

//this is inside an action in one of your controllers:
$file = file_get_contents('some.zip');
$this->getResponse()
->setBody($file)

Did you ever want to use just a single component from Zend Framework, but couldn't figure out which files you needed?

At The Group, we're developing some web applications that needed to use the same user database. The applications were originally being developed with separate login for each, but I decided it would be better to share the login code across them.
I investigated some ways to achieve sharing a single login ...

English
C or C++
A scripting language with dynamic typing
Why?

Today while reading PHP::Impact's refactoring guideline post I was reminded about collections.
As you probably know, arrays are very flexible in PHP and probably a good choice for many data storing tasks.
