Thanks man... it turns out that I really was redeclaring the class, but
it didn't throw an error until I added APC.
Kinda weird, yeah? Anyway... it's all good now.

So... I've got some code that works just fine without APC, but dies when

Here's the error:
Fatal error: Cannot redeclare class
that error doesn't tell us much more than you in the context you give...
but I'm gonna put money on the fact that your doing something like
include_once()ing
some class file then include_once()ing the same file but with a different
[relative]
path and that APC is getting confused thinking that these files are different...
try going through you code and making all [include|require]_once calls to use a
single
form of path (i.e. that all includes for a given file are identical)
you can use echo statements in the top of each class file to track down which
class is
seemingly being included twice.
if all that fails you can still use the 'apc.filter' ini setting to exclude
certain
files from being cached (using regexp declarations to exclude files based on
filename)
- this assumes your class files have a 'std' naming convention (e.g.
Foo.class.php).
I use the same technique to stop class definitions being cached to overcome a
problem
that my cached class defs cause segfault which I can figure out (that reminds
me I
should try a newer version of APC if it's been release :-)
php -v =
PHP 5.1.2 (cli) (built: Jul 18 2006 23:21:00)
... any ideas what's up? Obviously, there are other ways I can improve
performance on that box, but I'd love to try APC.
Thanks...

Hi everyone.
Could someone tell me if fpdf class can write the pdf file into the server?
I've reading about and just found that it save the pdf document in a local
place or open it in browser.
I need to write it in server, it's possible?
Thanks a lot.

Yes you can...
$pdf->Output("thelocation/filename.pdf", "F");
Just make sure that thelocation has permission to write for the web server.

Is a function return value copied? If the value is an integer I suppose
it is but what about a string or an array? If you pass by reference is
the return value still copied?
For example, is this:
function foo(&$arr) {
$arr[] = "bar";
}
faster than this?
function foo(&$arr) {
$arr[] = "bar";
return $arr; // is this copied?
}
I'm working on some code that would be called to generate a cell in a
possibly large table and therefore a small difference in performance
may have a significant impact.
Thanks,
Mike

PHP uses copy-on-write and so copies are essentially shared until such
time as you modify one of them. If you don't need references then copies
are faster than references.
Cheers,
Rob.

By the same token, then, if I have a function that generates a large string
and returns it, is there any benefit to return-by-reference?

Hello there,
I have a problem with rawurlencode().
I want to have the euro sign € to be sent by post.
To do this, first rawurlencode() encodes all the chars.
But for some reason rawurlencode encodes it to %3F or %A4.
Which i think is logical becouse that is the right position in the charset.
But i need it to be %80.
When i use rawurldecode('%80'); and put the browsers encoding to ISO-8859-* it
does work.
i Realy see the euro sign.
So why does rawurlencode() not encodes it tho this?.
Thx in advance.
Mathijs.
