something like this?
you can put it wherever you like and returns an array for further
processing. You could optionally add a second argument to set the index
to a name and check if the name exists to add 1 to the end of the name
so your indexes stay maintained.

That's not really what I'm after. Let me try an example:
function foo($id) {
static $foos = array();
if (empty($foos[$id]) {
$foos[$id] = load_foo($id);
}
return $foos[$id];
}
When load_foo() is slow (e.g., lots of DB traffic or remote-server calls
or whatever), such caching can have a significant performance boost.
Sometime after foo() has been called 15 times from 30 places in code,
when I get to the end of the request (or just every time I call foo()
would be fine) I want to be able to do something like:
$cost = get_memory_used_by($foos);
So that I can determine how much memory that caching is costing me over
the lifetime of the page, and determine if it's a worthwhile trade-off.

Currently it's mostly procedural with some components that are OO. I
suspect most of the memory sinks are large arrays (we have a lot of
them), but I am not certain of that. Hence my interest in more accurate
investigation tools.

Hi there,
In certain circumstances controlled by my users, I'd like to redirect
my users to another site, a third party whom we have contracted with.
The second site uses basic authentication with a simple username and
password. Can I write my PHP code so my users do not have to login
(or even know the username/password) on the remote site?
This isn't intended to stop serious hackers, just enough security to
stop casual passers-by.
Thanks,
Bill

depends on how that site does its authentication...
if it's a form, it may need an extra setting to allow you to go to a
specific page on that site after authentication.

Have a look at cURL (http://www.php.net/curl) as it will allow you to
perform remote POST's which may be enough to get you through.

Or you can use JavaScript on an intermediate page to post directly to
the remote site's login form. If JavaScript is disabled, just have a
button "Please continue to XXX" which then performs the post tot he
remote site.

Hi,
I apologise if this is not strictly php related. What Open Source Shopping
cart system do you recommend between osCommerce and Zen-Cart for ease of use
and a php guy with dangerously little javascript knowledge?
This is not for a massive shopping site, simply a cart to power a
subscription sign-up page.
Thanks for the advice.

At this point in time I would choose ZenCart over osCommerce since
development of osCommerce has languished for the past 3+ years at
version 2.2 and version 3.0 has been in alpha for just as long.

If it's an option, I'd recommend Magento. I've not used it, but I've
heard a lot of good things about it.

Haig:
A subscription sign-up page? That doesn't sound like a shopping cart problem.
You mean something like this:

For just a subscription sign-up I use a PayPal button. PayPal supports
subscription based billing.

Hi all,
I was upgrading php from 5.6 to 5.11 and came across one odd issue. Hope
someone could point out what is the problem.
Following code demonstrates it:
$xml = '<?xml version="1.0"
encoding="UTF-8"?><methodResponse><params><param><value><Test/></value></param></params></methodResponse>';
echo xmlrpc_decode($xml);
I suspect to get "<Test/>" as a result, but for some reason < and > are
cut out and i'm getting "Test/". So basically all entities are dropped
from response.
I have 2nd server running same OS (CentOS 5) which has been upgraded
first and it works as i suspect, code above shows "<Test/>".
Any advice will be much appreciated.
Currently I have temporary workaround for this:
$xml = str_replace(array('<','>'), array('<','>'), $xml);
but would like to fix xmlrpc somehow.
Regards,
Dmitry Ruban

Rather than providing an identical environment, you could use HTTrack
http://www.httrack.com/ to create a static mirror of the site which has all
the functionality of the dynamic site in static html form. Just stick the
mirror on a CD with an appropriate autorun.inf if you want it to autostart.
