I'm usually a lurker on here, but thought I'd through in my 2p on this
one...

Delphi (Object Pascal) has a similar feature, that I've had some
experience of using, and I never liked it. Why? Because it only leads to
confusion, mainly because the separation of object and method leaves you
unsure of what is actually being called.

Consider the following:

    function do()
    {
        echo "hello";
    }

    $class=3Dnew class;

    with($class)
    {
        do_something();
        do_more();
        do();
    }

Now, within my with(), am I calling the class method do() or the
function do()? Not clear at first glance.

And the whole thing gets even more complex if you can start nesting
with() constructs.

I suspect this wouldn't be trivial to implement, and for me it doesn't
add any value - only potential confusion.

hi,

i think it would be really handy to introduce the with() feature from
JavaScript (and probably other OOP languages) into php. so for sample
the following

---------------------------
$class=3Dnew class;
$class->do_something();
$class->do_more();
$class->do();
---------------------------

 could be made easier and more readable:

---------------------------
$class=3Dnew class;

with($class)
{
    do_something();
    do_more();
    do();
}
---------------------------

greetings

Sebastian=20
