$class->method()->method()

[edg]

This works:

$b = $a->method1();
$c = $b->method2();

I'd like to get this all on one expression, something like:

$c = ${$a->method1()}->method2();
which doesn't work.

Is there any way to avoid actually creating and then using the $b
object?

Thanks,

If I'm not mistaking you'll be needing PHP5 to use that syntax...
In PHP5 $a->method1()->method2() works, in PHP4 it doesn't as far as I know.

Use $c = $a->method1()->method2;

You'll need PHP 5 for this syntax.

$a = new A();
$c = $a->method1()->method2();

print $c;

Thanks for all the responses.

I suppose I should have posted that I have to use PHP4 :(
Any ideas for the more traditional approach?
