this is definitely my biggest concern but i take care of a handful of projects that are on shared servers. most are on 5.2 so i think i will use the same on localhost for nowQuote:
1. It is a good idea to learn with the newest trend and not learn any old bad habits.
If you're stuck with a particular version of PHP (i.e., on a shared server), then there is good cause to revert your local development version.
However, even in 5.2, using a reference to instantiate a class was not proper procedure - it just threw a notice, rather than a warning (which probably never made it to your screen). I can't find anything to indicate that it was ever used in any 5.x version; the only mentions I've found seem to place it in version 4, when OO programming was just being introduced to PHP (and not very well, to be blunt).
all in all, it just doesn't make any sense: the reference operator means you intend to work with the same contents as that which you're referencing. for example:
in this example,PHP Code:$myvar = 'value';
$urvar = $myvar;
$myref =& $myvar;
print $myvar."\n".$urvar."\n".$myref;
// prints:
// value
// value
// value
$myref = 'other value';
print $myvar."\n".$urvar."\n".$myref;
// prints:
// other value
// value
// other value
$myvarand$myrefliterally share the same value (not identical values, but actually two names for one box, as it were), whereas the value of$urvaris simply identical to$myvar(at the time it was assigned: it's a "copy").
doing this when creating a new class instance is pointless because there is no existing value to reference: as the keyword implies, the class instance is "new."
As I said, I'm just discovering this issue, so I may not have a complete grasp of it, so I'm sorry if something I'm going on about isn't quite right.

In any case, it seems the problem you actually had is solved. :)
i removed the & and that got rid of the error in php 5.3Quote:
The problem seems to be &new vs. new. Can you remove the & and see if it works?
did it have any negative effect, or any other effect, on code execution under v5.2 (I can't imagine it would, but in the interest of thoroughness)?
it worked fine i both 5.2 and 5.3. ive never seen that & sign used in conjunction with a new , was that something common in previous versions of php?
I'd never seen it before, either. I suspect (though I really don't know) that it was simply an early method of instantiating an object from a class, and was later made obsolete (perhaps due to a change in the object constructor model), but retained for backwards-compatibility. Whether or not it ever had any functional difference is another matter.
as a side note,$var =& new object();and$var = &new object();are equivalent statements (as would be$var=&new object();- because of how PHP parses whitespace).
i'd say the former is how it "should be" ("should have been"?) done, and the latter (from your script) is an oddity.
