[PHP] Crashing IIS?
Hi folks, I had the ... dubious ... pleasure of running some PHP code on an IIS system recently and noticed a peculiar occurrence... I called setCookie(), and something in it caused IIS to crash. Dead. Gone. Shuffled off this mortal coil. Stuffed. Like a parrot. :) As an alternative, I instered manual Header() commands to get the same effect as setCookie(). Same thing. Dead. Stuffed. Etc.

RE: [PHP] Server Setup
In the short run, its faster to install packages, and allows for easy upgrades. In the long run, if you compile from scratch you will get to know the system, you'll know more how it works, and it is (in my experience) MUCH more stable to compile it from source. I've installed PHP/MySQL/Apache combo on maybe 200 machines, and the numbers are for compiling everything from scratch.

[PHP] Re: The future of PHP - object model
Hi folks While we are on the subject of strategic issues for PHP, a quick question on the OOP functionality. As many on this list will know, there is a peculiarity with the PHP object model - in many situations it creates a copy of an instance when you would expect a reference. This means that you have to constantly remember to create references with &, adding an extra source of hard-to-find bugs. Are there any plans to sort this out? It rather disfigures the language. Yes, I know PHP was conceived as a functional language, but a high percentage of the more sophisticated applications make use of its object functionality - you just have to look at the script download sites to see that this is true. Both Perl and C/C++ are examples of successful hybrid languages. With just a little extra work, PHP could join this list...

Hi folks I asked my ISP to flesh out their negative comments about adding libraries to PHP.

As such, the question is simple and obvious: why does so much in PHP rely on the core's compile-time. Why can't there be run-time or DSO inclusion later on, as with Perl. Basically, PHP has really screwed up in this monolythic design which was all very well when it was a simple templating system, but now it's grown to a full-grown language, the scalability, flexibility and namespace issues are becoming untennable.

Re: [PHP] fix my query please
Well,
T1 INNER JOIN T2
For each row R1 of T1, the joined table has a row for each row in T2 that
satisfies the join condition with R1.
T1 LEFT OUTER JOIN T2
First, an INNER JOIN is performed. Then, for each row in T1 that does not
satisfy the join condition with any row in T2, a joined row is returned with
NULL values in columns of T2. Thus, the joined table unconditionally has at
least one row for each row in T1.
and as you can see join condition is nothing to do with equality of
respective columns, which means you can state any kind of join condition
(non-equal as well as equal join)

Re: [PHP] real optional parameters
yes, you just declare the default value of the arguments such as : my_function ($first = 'no-value', $second = 0, $third = null ) Note that the default value must be a constant expression and any defaults should be on the right side of any non-default arguments or you can achieve the very pretty function-overloading using the funtion handling function.

Well, I tend to prefer compile from source as well. I guess they simply don't realize that you can compile most of the extensions as shared libraries and configure what should be loaded at runtime in the php.ini file. So it looks like this is mostly a documentation issue. We have not done a good job educating the ISPs out there. But they should have been able to figure this out by looking at how PHP is packaged by the various distribution vendours. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

i can think of several:
1. write an extension. it'd probably have to be C though, or you'd
have to figure out the name-mangling if you wanted C++ in there.
*while this is powerful, i would avoid it, myself because i
prefer to work in C++ and the linking problems would take
too much effort and time to deal with.
2. use pipes (popen) on the C/C++ process.
A. this is an easy way to do things if the C/C++ thing is
a one-shot deal (set command line params, read
answer in stdout or return value).
B. it's also a reasonable solution if you have half-duplex
pipes and you only need to send data once (on command
line) and read many lines of answer (use read mode, so
"r"). or you need to send a lot of data to the program
and you only need it to return a status code (use "w"
mode and encode reply in return value from main(...)).
C. this can be a general solution if your system supports
full-duplex pipes (popen mode is "rw") since you can
then set up as much interactivity as you want between
PHP and your external program.
using pipes and exec can be expensive. think about usage
patterns before committing to this approach. it's a nice
thing for quick and dirty solutions though.
3. write an application server. there are two types, both
types have some common features. in general, you ask
the application server to perform a service for you, you
give it parameters, and it returns the answer.
A. socket based server. the server sits on a socket,
PHP opens connections to that socket and the
server returns the answer back through the socket.
B. exec or CGI based server. if the server is an external
program that conforms to CGI, it could just be
invoked via something like fopen("http://","r";);
you pass it parameters through GET (urlencoded
on the command line) and you read lines from the
program.
a socket based server (either fork-style, like apache, or
using select so single-daemon style, or perhaps using
threads, on OSs that support them) is probably the least
CPU intensive, but it's also harder to write.
i've done all of the above, but with another language and
C/C++, not PHP. with PHP i've used the popen thing
with good success (it's the most convenient solution),
but you really need to think about usage patterns there
because spawning off processes like that is expensive
and will affect server responsiveness when you start
getting a lot of hits. my applications were only hit
once every 15 to 30 minutes or so, so efficiency of
resource use wasn't a big deal :).
