Hi all!
Recently I am getting the following error on some of my PHP-enabled websites. I
think it started when I went from PHP4 -> PHP5.
Here is an example (from http://wos.poboxes.info/) :
Fatal error: Call to undefined function preg_match() in
/var/www/wos.poboxes.info/htdocs/classes/ConfigData.php on line 114
What causes this? How can I fix it?
FYI: I use Cherokee (not Apache...)

Evert

So it works on the other pages on the same webserver?
Probably you have unset the function, or some file/php/include/script does.
Best way to test that is to put preg_match at the first line.
Is a htaccess causing trouble probably?

Since when can you "unset" functions from within php scripts?? (except
with specialized modules, which we'll just ignore for now).
My guess here is that the PCRE-library was disabled during compilation
of your PHP5 tree (check phpinfo for that). If so, you'll need to
compile it in to have the functions.

He went from 4 to 5, do you know what 4 had compiled in? no you don't.
Why don't just ignore he went from 4 to 5.
So we can see this post as "i installed php 5 and got error X"
Sorry, i think that's big nonsense.

You're right! :-)
It turned out that php5 was compiled without pcre-support. I have recompiled
it, and now it works like a charm! :-)
Thanks for the help! :-)

Doesn't make sense for me ...
If the OP is capable of installing and using the runkit extension
them he would never have had ask the list why 'preg_match() is not defined' -
it's a fairly basic problem to solve - anyone with enough skill and experience
to use runkit would know how to solve it.
obviously Barry you are very experienced and use the runkit extension all
the time ... because evidently you seem to think 'unsetting' function
is a completely normal activity inside a php script.
>>Recently I am getting the following error on some of my PHP-enabled

He went from 4 to 5, do you know what 4 had compiled in? no you don't.
Why don't just ignore he went from 4 to 5.
given that he says 'I think' (i.e. he's too lazy to check and know for sure)
ignoring the fact that he upgraded is actually quite sane.
the OPs problem is an undefined function which can only really mean that
an extension was not loaded (and/or not compiled in) - nothing to do with the
fact that he upgraded as such (he could jsut as well have got this error
if he had created a completely fresh php install)

Hi all,
I'm wanting to define a static method on a base class that then
instantiates and returns an object of the type the static method was
called on. I've searched the docs and Googled but everything I find says
it's not possible and I just wanna check to make sure before I admit defeat.
Say I have the following...
class Foo
{
public static function & Create()
{
$classname = ???;
return new $classname;
}
}
class Bar extends Foo { }
$obj = Bar::Create();
What do I put where the ???s are? I've tried __CLASS__ and get_class()
but both give me the base class name. Short of passing the classname to
the static function I'm at a loss as to how to do this. However,
Bar::Create('Bar') is a bit too sucky for me to be happy with it and
kinda defeats the object.
Thanks.

either suck on it or use another language :-P.

there has been discussion of this problem on the internals mailing list,
most of them seem to agree something is required here but no definite

I thought as much. Shame really, I had a really elegant solution planned

I am having trouble porting some code originally written in Borland Delphi
to PHP. The Delphi code expects certain behavior on integer overflows that I
can only duplicate on some PHP systems. For example:
$BB = -2181087916;
$AA = (int)$BB;
$AA = intval($BB);
On some systems, $AA will be (int)-2147483648, however, on most systems, $AA
will be (int)2113879380, which is the same value truncated at 32 bits. It is
this latter behavior that I need to properly port the Delphi code.
Can someone suggest a way to do this that is consistent on all platforms?
For reference, I am attaching the Delphi code and my PHP port.
Thanks...

Two modules that come to mind:
http://php.net/bcmath
http://php.net/gmp
Since your code does some or and xoring gmp sounds like the GMP
method will be the best one. The down fall is it will add the
requirement to add the library and rebuild php with it.

CSS is probably the best solution
http://www.w3.org/TR/REC-CSS2/page.html#q16
found whle googling
http://www.google.ca/search?hl=en&q=printing+CSS+media&btnG=Google+Search
This is a good article:
http://css-discuss.incutio.com/?page=PrintStylesheets
and as always, A List Apart has CSS Design: going to Print at
http://www.alistapart.com/stories/goingtoprint/
I have seen examples of two-column pages, but do not know if the pages
broke correctly when the matter was longer than one page.
Alternately, display in tables and make certain you have a <TH> so your
header can repeat.
Hope this steers you in the right direction - Miles.

Yeah, they have their new Payment Pro system which has a gateway
API. I dont think they have any preference over the other.
One of the biggest advantages with IPN is you dont have to worry
about handling credit card numbers and how you are securily
handling them. But then again like you said it is a bit clunkly to
add to a payment system, and if paypal somehow fails you have to
jump through hoops to figure out what happened and what to do next.

Not really. The state of a transaction can be easily verified.

Easy, yes. That wasn't the point really though. Their true API offers
you a truly site integrated experience, IPN does not.

Considering the way a typical ipn transation works there are
several steps involved in the whole transaction that could be the
problem.
1. You send user to paypal, with item and amount for item.
2. paypal veryifies user and the amount the user is going to pay.
3. paypal contacts your callback script that should validate the
transaction.
4. paypal provides a link to the user to return to your site with
data related to the transaction.
There are several problems in which are hard to tracedown:
- Network problems
. Paypal is unreachable
. Paypal can't resolve your callback script
. Your site is unreachable when the user finishes with paypal.
- Script problems
. Paypal doesn't ever call your callback script
. Your callback script has a logic error/parse error, so you
can't verify the transaction but yet paypal still transfers
the funds.
. Paypal changes their API to post data to their system
. Paypal doesn't post transaction related data back to your
script.
- User problems
. User modifies a price for a product that is being posted to
paypal, instead of paying $100.00 they change the value to
$1.00.
. Any Network problem or Script problem causes the user to get
frustrated with your system.
. User never clicks the 'Return to site' button so you never
really know if they've completed the transaction or their
browser crashed somewhere.
If you use a gateway to process funds within your script, it is
much easier to catch these points of failures. Since this system
can keep track exactly at what point something failed it can
gracefully respond to the the user of the status.

I have a script that periodically sends an email that includes form
post to a script, which is meant to do something with the posted data.
My problem is that apparently some PHP security measure is not
permitting the externally posted data to be access via $_POST. I
assume this is due to cross-site scripting issues, but in this case,
I want to do just that. Any ideas?
