calling class method (with constructors) without object instantiation in php

Question

Ive looked and tried but I can\'t find an answer.

In PHP, is it possible to call a class\' member function (when that class requires a constructor to receive parame

I, too, was looking for a one-liner to accomplish this as part of a single expression for converting dates from one format to another. I like doing this in a single line of code because it is a single logical operation. So, this is a little cryptic, but it lets you instantiate and use a date object within a single line:

$newDateString = ($d = new DateTime('2011-08-30') ? $d->format('F d, Y') : '');

Another way to one-line the conversion of date strings from one format to another is to use a helper function to manage the OO parts of the code:

function convertDate($oldDateString,$newDateFormatString) {
    $d = new DateTime($oldDateString);
    return $d->format($newDateFormatString);
}

$myNewDate = convertDate($myOldDate,'F d, Y');

I think the object oriented approach is cool and necessary, but it can sometimes be tedious, requiring too many steps to accomplish simple operations.
