[PHP] Creating my own External Module for PHP

[Leon Mergen]

Hello,

I have a little question to which I hope to find an anwser in here.
Currently, I have a big script which receives approx 1.5 million hits every
day. Since this script does some common calculations that underlying scripts
use, I want to rewrite this into C and initially make it an external module
for beta testing and then eventually compile it directly into PHP.

Now, I got this really good book, Web Application Development with PHP by
Ratschiller and Gerken. It has a complete chapter devoted to "hacking the
core of PHP" which shows how to create extensions.

Now, they describe 2 common ways of hacking the core... making a shared
object (which is what I want at this point) , or compiling the extension
right into the core. They decribe how to make your extension with
~/ext/ext_skel , but they don't describe which steps to take when you only
want to make a shared object... the only thing they say is "at this point,
you should have a new PHP binary or a .so file" ... but they never gave any
indication how to chose... they just asume you want a new php binary or sth.

Now, can anyone provide me with a few brief description (a few steps) how to
make your own dynamically loadable module in PHP?

Thanks in advance.

Regards,

Leon Mergen

I think that the only source that could cause any problems with too many
files included will be your operating system (since that thing has certain
limitations on a max number of locked files for example) . Other than that,
I don't think so. I myself include about 15 files on certain pages. But it
is easy to make a test or anything...

Just make a PHP script that generates like 1000 php scripts called
"include.test.x.php" , where x is is a number, then the contents of those
scripts should by "" or
something like that...

Then you are for sure, and you immediately also know how much performance is
lost for including 1000 files :)

Hmmm, i think the parser is built recursive, so at the moment it sees an
"include 'foo';" , it will look in foo, parse that one, and after it has
finished foo, it will continue with the main script...

Somebody correct me if I'm wrong, but from what I know is that when using
shared it is compiled as a shared object and only loaded when needed. This
decreases ram usage (which is good) , but increases load (which is bad) .

If you have a few spare kb's of ram, I wouldn't recommend using shared...

Heck, I don't have anything better to do at the moment anyway. All I can say
in first, I will not judge your style - it's all up to you.

Now, first of all, why did you this:

"); ?>

and not just:



? Less parsing for PHP :P

But other than that, I couldn't find anything very wrong about it... only
that I personally prefer to call a print() statement for everything, and
don't use PHP as an embedded language but just as a normal programming
language... But that's just me :P

Hope this helps you a little bit...

Re: [PHP] How know how many sessions are active?

[Leon Mergen]

To help even more, if you're on a dedicated, this shell command will provide
you the amount of sessions active:

"ls -l /tmp/sess* | wc -l"

HTH

"Justin French" <[EMAIL PROTECTED]> wrote in message
[EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
If you're on a dedicated server (no other sites on the server), you could
just count the session files in /tmp.

Otherwise, the general consensus seems to be that you need to decide how
long a user is "active" for (say a minute, or 3, or an hour?), and save (eg)
the SID and timestamp in a file or MySQL table.

In theory, you then count the number of sessions that were created or
reactivated (restamped) within your definition of "active" time (eg 3 mins).


This has been discussed waaay too many time on the list... do a search on
the archives for 'active users', perhaps also try a search with the word
"ASP" too :)

If I understand correct, you will want something like this:



And now, in all the scripts on your site, when you execute the
session_start() function, $_SESSION["var"] contains the original contents of
$_POST["var"] .

No, if everything is setup correctly both will work now. Otherwise, a lot of
websites would have many many problems with the transition phase between
register_globals = on and register_globals = off.

So this would handle 2-demensional arrays too?

So, if I have

);


it would work?

Hello Andy,

My suggestion is to just make a HTML file, do an auto-refresh or sth to the
url with a variable ?start=$x , and make that refresh after 2 seconds...
your php script sends emails to 25 people per cycle, and you just walk away
from your computer and let it run for a few minutes...

I do that for my mailing list which is over 30,000 people large...

If you don't have the time to build something like that, there's always the
BCC option ;)

Hope this helps you.

[PHP] unset($array[value]) does not work?

[Leon Mergen]

Hello,

I am currently testing out some things with removing elements from arrays,
and I find it strange that the following statement does not work for me:

unset($array['element'])

I wrote a little test script, you can see the source at
http://www.antrophia.com/test.txt and the executable at
http://www.antrophia.com/test.php ... Now, if you look at the last part:

unset ($unserialized['foo']);
if (key_exists("foo", $unserialized)) { echo "foo exists!\n"; }
if (key_exists("wom", $unserialized)) { echo "wom exists!\n\n"; }

You will see that $unserialized['foo'] still exists! Can anyone explain me
what I'm doing wrong?

Thanks in advance,

Hello Philipp,

I think that must be because it's the most easy to explain... It's very easy
for people having experience with Perl, since Perl works that way...

I personally only use templates (I even wrote a caching template engine) ,
so that would be the last step in layout I think ;)
