Hello Roman


    there's no standard filename extension for PHP-serialized data,
    I'd just use txt or something... .psdf or whatever.


.ser is used for serialized Java objects and I've found .jser also
being used (though less frequently) for that. On the analogy of the
latter I'll plump for .pser.

But what file extension should I use for PHP's serialization format? Obviously it can't be .php - aside from being inaccurate (it's not PHP code), using this extension would probably trigger the web server into trying to run a (nonexistent) PHP script.
Given that file extensions are purely for association purposes and no application I am aware of knows what to do with PHP serialised data, personally I would use .dat. Or, if I wanted it to be more descriptive, something like .phpdata. But to be perfectly frank it doesn't matter.
Small suggestion though... rather than falling back to the evils of mod_rewrite, enable multiviews and you can have URLs such as... 

staff/engineering/data.json

Or whatever filename you want.

I know of one website (Livejournal) that has /url.../data/rss or
/data/atom etc.  /data/php, /data/wddx or /data/json are pretty
obvious extensions to that.

That said, since all are them are designed for a script to consume,
and not a person, I'd call them entirely 'clean' and obvious enough
for the task, though ultimately, it's about having a pretty URL, as
the program that reads it won't care what the extension is, if any,
and people won't be typing it in regularly anyway.

.phps is taken for PHP Source, so using it for PHP Serialized would be
Bad.

Perhaps phpd for PHP Data would suit you.

You could make it anything you want, as far as I know.

Actually, you could make it be .php and use ForceType in .htaccess to
do what you describe, but that's probably not a Good Idea for clarity
sake.

I take that back -- you wouldn't need the .htaccess and all that, as
you are already doing that with the 'staff' file and 'engineering' is
just part of your $_SYSTEM['PATH_INFO']

Given that a variable probably costs X and that any variable cane be
stored as Y in an array, and an array would cost Z where the Z = X * Y _
1 (Y element + 1 for the array container itself).

Then the range format would cost 31 + 1 (the array itself + 31 entries)
whereas the for loop would cost 1 + 1 (cost to store i + cost to store
endpoint comparison. Thus the damage is about 15*. Given general
computer science consideration, this is a constant and thus practically
neglible.

You can use PHP to instantiate a Java thingie, but, honestly, if you
want real-time interaction with the browser and a robot, I think you
probably should just be using Java.

is the solution that is best-suited to what you want to do.

I'm not saying it CAN'T be done with PHP wedged into it somewhere;
Just that you're shoe-horning something into a shoe that doesn't fit.

Select the correct weapon.

At the top of your script, are you calling php with the q flag:
#!/usr/bin/php -q

That's the only way I can get php to run from the command line on linux boxes.

No, it's running otherwise he wouldn't even see the function error message.

It's most likely installed as he doesn't get the error when running
the script in a browser. Unless he means that he's running the test
script in a browser on another server.

Run a phpinfo.php, with one function in it: phpinfo(). Do this from the command line to check that PHP, from the command line, has the module necessary to connect to Oracle. Sounds like it doesn't.
I've not worked much with PHP on Windows, so I guess you would make certain you have the .dll for Oracle and enabled it in PHP. 

The browser and the command line are two completely different environments.

sounds like the CLI is loading a different ini file than the webserver SAPI ...
and that the CLI php.ini file does not load the oci extension (where are the
ini file for the webserver SAPI does load it).

You need to use the -c flag of php.exe to find the same php.ini as the
working version.

You're not using the same php.ini, or you're using NO php.ini on the
one that works.

Hi,

I wanted to give some feedback on PHP 5 hosting in case it helps
someone.  I signed up with DreamHost last Thursday.  I also signed up
with OCS Solutions to compare the two services.  I also maintain a
server with CalPop.

When I signed up with Dreamhost, I discovered that you have to fill
out a form and fax it to them, along with a rubbing of your credit
card.  Personally, I found that part rather annoying.  They say it's
for added security, but I've never had to do that with any other
online transactions that I've done.  OCS Solutions had me pay for a
year up front, which always makes me nervous when checking out a new
provider, but they do offer a money back guarantee.  Actually, both
providers offered a money back guarantee.  DreamHost's is 97 days.
That's pretty good.


They require that you fax them a rub or your credit card?!? I
certainly wouldn't do that!


Cost-wise, both companies were fairly inexpensive.  I ran a Google
search for "DreamHost Coupon" and found a coupon that eliminated a
majority of the up front cost.  Actually, I was pretty surprised.
They give you a free domain registration that includes private whois
for free.  After the coupon, I paid $9.90 and covered the start-up
fee (normally $45), the first month of service, and the domain
registration.  It feels like I paid for a domain registration and got
free hosting for a month.


Nice!


My account with DreamHost was created on Monday.  Technically, it
took 5 days to get my account set up.  That's the longest set up
delay I've ever experienced with any host provider.  OCS Solutions
called me an hour after signing up and had my account setup shortly
thereafter.


That's all it should take.


I also registered a domain when signing up with OCS Solutions.  The
whois was wrong.  Somehow it ended up showing as registered to one of
their employees, but I called and they quickly fixed it.  The account
was set up under the wrong username, but they fixed that quickly,
along with problems with cpanel when it doesn't handle the name
change correctly.  Mistakes were made, but I was really pleased with
how easy it was to get help and I was really happy with how much
people obviously cared about helping out.

After signing up with DreamHost, the domain that I'd registered with
them wasn't working.  I was exploring their control panel to figure
out the problem when I came upon a DNS management page.  The page
automatically identified and fixed the problem.  That was impressive.

Also, I started exploring the DreamHost forums after signing up,
something I almost wish I'd done beforehand.  I found a lot of posts
from very disgruntled customers.  It sounds as if they've been
running into problems lately on their servers.  People complain A LOT
about the lack of phone support from DreamHost... you have to submit
a trouble ticket for everything.  If your account subscription is
high enough, they offer a limited number of call backs.  The worst
part was reading debates between the really happy and the really
unhappy DreamHost clients.  A lot of the discussions boiled down to
verbal attacks between customers.  I'm honestly surprised DreamHost
didn't intervene.

One last thing with OCS, the plan I started on turned out to be
insufficient for my needs.  I talked with them and they came up with
a new plan that does everything I want and just charged me a little
more to cover the difference.

End result so far...

CalPop: I've always had problems with the initial set up of servers
at CalPop.  Talking with their tech support on the phone is a
nightmare; there's something wrong with their phone lines (seems like
a really bad voice over IP solution).  It usually takes way too many
emails to resolve problems.  I've also experienced a lot of hardware
failures, which makes me wonder about the quality of parts they
purchase.  Once the server works though, everything seems to settle
down until the next problem shows up.

DreamHost:  Best prices, low service.  It seems like DreamHost is run
by and tailored toward experienced techies.  That's fine, I can work
with that.  I'm willing to try working with limited phone support.
I'm really only concerned with delays I might experience when a
problem shows up in something that's mission critical.  Beyond that,
there are a lot of features available here that aren't elsewhere.
I'm getting great value for my money.

OCS Solutions:  Good prices, but you have to pay up front.  Best
customer service I've experienced from an ISP so far.  I feel a lot
more comfortable using them for anything mission critical.

I *think* they do this only when the credit card does not sail through
automatically.  Like if you give a shipping address different from
your home, or your cell-phone instead of home phone, and then the
ultra-stringent CC checks they have turned on kick back the
transaction as suspect.

Or so they explained it to me, when I had the same reaction.

At that point, I suspect you'd be faster to start over and be more
careful about matching up your CC input with what the bank has "on
file"

PS  A Sharpie does not make a good rubbing tool, no matter how gently
you try to press. :-)

Found this on Google:

Then Goto:
 http://mcrypt.hellug.gr/mcrypt/index.html
where it says:

The 2.6.x versions of mcrypt do not include Libmcrypt
The 2.6.x versions of mcrypt need Libmhash 0.8.15 or newer

It has a download facility.

I've upgraded all the services on it like going from Apache 1.3.x to Apache 2.0.59 and PHP from it's old version to 4.4.2 however I need to have mcrypt compiled with PHP and I'm running into a problem.
If I compile PHP without mcrypt I can install PHP without issue. However, when I try to compile PHP with --with-mcrypt=/usr/local/mcrypt I get the following error:
main/internal_functions.lo -lcrypt -lcrypt -lmcrypt -lltdl -lresolv -lm -ldl -lnsl -lcrypt -lcrypt -o libphp4.la /usr/lib/gcc-lib/i486-suse-linux/3.2/../../../../i486-suse-linux/bin/ld: cannot find -lltdl

Now I went back and compiled without mcrypt and looked for that line and this is what was there:
main/internal_functions.lo -lcrypt -lcrypt -lresolv -lm -ldl -lnsl -lcrypt -lcrypt -o libphp4.la
I see that along with -lmcrypt not being there neither is -lltdl is there something I'm missing? Do I need to have something else installed on the box? Normally I haven't had this problem with this. But this is an old suse 8.x box that is being used due to time frame issues.
Like I said I can compile PHP without mcrypt, but the project requires mcrypt so any help on this would be appreciated. 

Thanks!

Can you check to see what session identifier the browser is sending when
you get this error message? PHP's session identifiers should only
contain hexadecimal characters (a subset of alphanumerics).

This check was added to protect against people trying to use the session
identifier as an attack vector, sending a malicious payload instead of a
real session identifier.

Hope that helps.

Can you check to see what session identifier the browser is sending when
you get this error message?

how can I check the session identifier the borwser is sending?

Also, why are you assigning the result of session_id() into a variable that
is then passed into $_SESSION. Seems overcomplex and redundant - why not
just call session_id() when you need it? Just a thought.

Whatever you've been cramming into session_id(), you shouldn't have
done that.

A username should be ENCOURAGED to have at least one non-alphanumeric
character.

session_id()s are NOT ALLOWED to have any non-alphanumeric characters.

By default, div is a block element and span is inline, so span seemed like the natural fit for a sentence fragment. I don't think there's anything old-world (!) about spans, Tedd, they're just tags. I use both in my markup with a clear conscience.
My bad -- spans just remind me of the old "How do we slip things in" days instead of figuring out a way to work around it. I realize that they are both tags, but as Stut reminded me, one is block and the other is line element.
However, if you used preg_match_all, I think you could do away with the spans all together by matching FIRSTNAME to your first name variable. That way your document would simply read: 

       Hello FIRSTNAME
That's true, and in tighly-defined micro-contexts that might work just fine. For a robust general CMS, though, I want a completely unambiguous demarcation of replacable content. All-caps tags will work in some circumstances but certainly won't in others.
If you want "a completely unambiguous demarcation" then use xml with a defined schema. I don't think you can get any more defined than that, right? 

Cheers,

tedd

 I also embed php variables inside css -- it gives it more functionality.


I embed them in the CSS template, which is compiled to a CSS stylesheet
file and so the variables become static after compilation. This is
useful if you're not determining values by any PHP logic, since then
your stylesheet can be served up as a static document while retaining
the flexibility of using variably defined values to generate the
stylesheet.

Cheers,
Rob.


Rob:
I think that's the only way it can be done except doing things with Ajax. If so, then styesheets can become "dynamic" -- but when served, they are static.
For me, I just provide a header at the beginning of the css file and a .htaccess rule to treat css suffix files as php documents.

I wrote my own phpmyadmin from scratch, so far i got this

to change so other people would like it too ?

I only have tested it on firefox so for now IE probably doesnt like
dfo at all, sorry i will fix it later for IE 7. And i also forgot to
put the start page in the readme  http://localhost/db/htm/datagrid.htm

Ok, What specific documentation do you want i start with ? i was
hoping it would just work on every firefox and php 5< mysql 5< server
with one small change to the php.ini to disable magic quotes see
http://php.net/manual/en/security.magicquotes.disabling.php

Using it should be quit simple if not i failt to do so. It should work
like point on the field do what you want to do with the field and if
you are ready to upload, push on the green V. The only thing that
maybe could be a bit strange in the begining is the login. I created a
cookie database that remebers all your servers and you need to select
on using the select options to go to the databases bij pushing on the
V button after you selected your server.

Thats it download check the ini and goto startpage
http://localhost/db/htm/datagrid.htm

When you get more Documentation I will check it out.

Your OS caching system doesn't know the difference between data files
that may or may not get re-used, and PHP scripts, like your homepage,
that are getting the crap beat out of them when you get slash-dotted.

The OS caching can build up a history of oft-used files and if you
have, say, a hit-song MP3 that's getting downloaded 1000 X a second,
is probably the way to go.

But if your goal is to get your codebase into RAM so that it can load
up what seems like a random distribution of data, a code cache is the
way to go.

If you're not sure what the hell you're doing, use both and play with
the parameters until it's fast enough, then focus on something else.

It's really not that practical to do that separation and unload code
objects, when the user could call any function at any time.

Particularly with:
http://php.net/eval
$function = 'myprint';
function myprint ($foo) { print $foo; }
$function('Hello World');

It is a very common misconception.

I think MOST people actually get this "wrong" on their first encounter
of a code cache.

Almost for sure, the in-memory tokenized version is not only shared
within a thread, but across all threads.

Otherwise, your cache would be loading hundreds of copies of each
script for all the Apache children.

The dispatcher may "copy" the tokenized script in order to run it with
a clean slate, but the "source" it uses is probably shared RAM.

At least, so I presume...

Almost for sure, that 20MB is never actually about the Drupal code
itself.

Loading in and manipulating an IMAGE using GD, or sucking down a
monster record-center from a database, or slurping down a bloated
web-page for web-scraping and converting that to XML nodes and ...

It's not the CODE that is chewing up the bulk of your 20MB.  It's the
data.

I may rant about OOP code-bloat, but I don't think it's THAT bad :-)

Your idea to use 'COUNT(Username)' is just about the ONLY part of that
script that you are doing correctly...

:-)

Start reading here:
http://phpsec.org/

And the header("Location: ...") requires a full URL.

And you should have better error-checking, probably.
[Though maybe you have a custom error handler not apparent]

And your DB password should probably be a hash/crypted value.

And it looks like maybe you are using register_globals "on" which is bad.

Once again, start reading:
http://phpsec.org/

Right. I skipped that part to not "waste" space in post. $_POST values are
checked first and then used.

Correct. I use this, of course.

Nope! globals are off.

Hi,
Recently I discoverd Memcache daemon for sessions, I'm very pleased its 
performance.

I want to use memcache other than $_SESSION

For example, I have an array, it  has language definitions. Normally on each 
page load I have to include that file. 

So I want to put that array into Memcached and access from each different 
SESSIONID, I believe this will reduce memory usage and gives performance 
boost.

I found (and use) SESSION examples for Memcached usage. Does anyone has any 
other examples for memcached usage.

Regards.

Sancar
