Create new class from appended string

Question

Is it possible to do the following in one line? For instance, something like $obj=new "entry_{$type}"; Thanks

$class="entry_{$type}";
$obj=new $class();

And of course it's so critical for code to be reduced to a single line wherever possible — Mark Baker, Feb 16 '13 at 18:32
Thanks all. No, it wasn't so critical. Just wanted to better understand. — user1032531, Feb 16 '13 at 18:33

Yes, but only if you really want it. It's a bit awkward:

$obj = new ${!${''}="entry_$type"}();

From: Code-Golf: one line PHP syntax

PHP wants to eventually move to a proper parser that uses an Abstract Syntax Tree, which might tighten up syntax holes that currently prevent, for example, new ("entry_$type")() or something like that.

Egads! It answers the question, but I will definitely stay with two lines! – user1032531 Feb 16 '13 at 18:36
