New Comment:
One interesting use for this would be as an alternative to the
convention of using method chaining with setters. For example:
$definition->addField(new StringField('username'))
->setRequired(true)
->setReadonly(true);
Is becoming a popular convention, but requires all your setters to
return $this, which I personally dislike, and this pattern cannot be
used with existing APIs such as PEAR modules.
Using the with statement, would facilitate the method chaining setters
pattern without requiring hacks to your APIs. For example:
with ($definition->addField(new StringField('username')))
{
->setRequired(true);
->setReadonly(true);
}
This would require only that addField return the added object, which is
more palatable to me compared to all setters returning $this.

Anyway, use objects.

or perhaps for a long piece of code that would be used a lot. this ugly
rectangle of code for example:
$server[$currServ][$currDB][$currGroup][$currUser]['access']=4;
$server[$currServ][$currDB][$currGroup][$currUser]['email']='';
$server[$currServ][$currDB][$currGroup][$currUser]['lastlogin']=0;
$server[$currServ][$currDB][$currGroup][$currUser]['projects']=array();
becomes
with($server[$currServ][$currDB][$currGroup][$currUser]){
$['access']=4;
$['email']='';
$['lastlogin']=0;
$['projects']=array()
}
kind of like a function that's created on the fly and then destroyed
when it's finished

Description:
------------
Visual Basic has a neat little code trick that I'd like to see in
PHP...
With object1
.property1="value"
.function1()
End With
And it can be nested. This is useful if you don't want to create a
variable to hold the return of, e.g. a function call that returns an
array, when you only need it for two or three lines.
Reproduce code:
---------------
with($nested_array['a_very_long_key']){
$[0]='apples';
with(function1($[1]->data))
echo template($['title'],$['content']);
}
// or
with $object1:
with $->property1:
function1($['key_of_property1']);
endwith
endwith
