Hello list,

I've always used Unix Timestamps until now, but lately I've reading about
MySQL's datetime datatype and its benefits (dates before 1970, after 2030,
SQL functions to deal with them, etc). However, I don't see much support for
them in the PHP API. I'm also a Flash programmer and the Flash 8 API Date
datatype also only understands unix timestamps. Taking this into account,
I'm not really sure if it really worths it to "move" to the DATETIME
datatype. What would you do? Any advice would be much appreciated!

Marcelo.

I use always unix timestamp as well, except in birth date.

I tend to stick to unix timestamps as well, because date formats are 
completely unstandard between different SQL databases.  MySQL's date futzing 
functions are nice, but they're different than Postgres', which are different 
than Oracle's, etc.  

Generally, most of the the math I need to do I can do in PHP either before or 
after grabbing the timestamp.  

I am sure there is a counter point, but this for what I do I just stick to 
timestamps. :-)

Hi

php5

<code>
$d = '/somedir/subdir';
$od = opendir($d);
if ($od) {
    $dl = scandir($d);
    natsort($dl);
}
</code>

The sorted array is available through print_r().
How can I obtain a natsorted array that can be listed using :

while ($i <= $array_count){print $dl[$i]}



Thanks

natsort() places the array elements in natural order but not the keys.
If you want your elements printed using "print" in a loop either reorganise the keys first or use "foreach". 

The easiest method would be to use:

foreach($dl as $filename){
        print $filename;
}

If you insist on using a while loop you could use:

$dl = array_merge($dl); to reorder the keys from 0 to array size-1.

then use:

while ($i <= $array_count){print $dl[$i]; $i++;}

If you use "while" you must increment $i to get all of the elements printed.

Alternatively you could use a for loop after reordering the keys:

for($i=0;$i<sizeof($dl);$i++){
        print $dl[$i];
}

hey all,
I'm moving my page from php4 to php5 and I get this error:
Warning: Unknown: The session id contains illegal characters, valid
characters are a-z, A-Z, 0-9 and '-,' in Unknown on line 0

this is the code I use to start my session:

$_SESSION['user_id']=$user_id;
       $_SESSION['user_login']=$user_login;
       $_SESSION['user_pass']=$user_pass;
       $_SESSION['user_level']=$user_level;
$_SESSION['session_bool']="true";
$sessionid = session_id();
$_SESSION['session_id']= $sessionid;
$user_real_id=$_SESSION['user_id'];
$user_real_login=$_SESSION['user_login'];

$realsessionid = $_SESSION['session_id'];

any idea what's wrong?

thanx in advance

Hello List,

I have a situation where, when the user logs into the system (Apache 2/PHP 
5.1/Win XP) the php script should activate a Java program to run in the 
background. This program will keep running in the background while everytime 
the user requests something, the subsequent php scripts communicates with 
this Java program on a preassigned port. (This is for controlling a robot I 
descibed in on of my earlier mails)

My questions are:

1. How do I make the Java program to keep running even after the PHP script 
terminates. In Linux I would have easily done using '&' - how about windows?

2. What is the safest way to do it?


Thanks in advance.

Prathap

P.S - Richard & Tedd - I appreciate your comments on my previous issue.

Does the Java program HAVE to be started by a script?  I've worked in a few 
places that had desktop apps that would just run on startup, or a service, 
and then the webserver/php would communicate to it since it's already 
running.  The downside to that is manual intervention when the program stops.  
Although... you could probably to an exec() and if it was installed as a 
service you should be able to run "net start <appname>' (or something like 
that.

I haven't kept up on your previous post so I may be completely wrong ;)

Ray,

Nope - I cannot have the program running all the time because the port that 
it this program will connect to will be accessed by other programs too. So it 
needs to run only when the user is online and logged into the system.

Any ideas?

I kind of mentioned it before, but what about making the java program a 
service?  Then you could exec()/shell_exec() "net start" or "net stop" as 
needed.  Beyond that I don't have any ideas without checking Google.

Yes, there may well be ways to get round what the web server would
otherwise do when it encounters a .php extension, but I feel that I'd
be breaking an expectation. I'd much rather use an extension that was
specific to the serialization format.

You could "convert" it to a php file:

RewriteCond %{REQUEST_URI} *.json
RewriteRule ^(.*).json$ json.php?$1 [T=application/x-httpd-php,L]
Might not work straight away but that should give you an idea of what's possible.

    Hamish,

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

Thanks for continuing to work on this, but I'm afraid my inadequate
explanation has sent you in the wrong direction. Let's see if I can do
better. Forget for the moment that the files are generated dynamically
and instead suppose that they were static files. An example of a file
containing JSON data would be engineering.json. But what about the
equivalent information in PHP serialized format? Calling it
engineering.php would be inappropriate for the reasons I gave before.

As far as I know, the files are only loaded as execution hits them.

If your code contains:

<?php
  if (0){
    require 'foo.inc';
  }
?>

Then foo.inc will never ever be read from the hard drive.

You realize you could have tested this in less time than it took you
to post, right?.
:-)
I don't know the extent to which the engine optimises performance, and I know very little about how different versions of the engine deal with the issue, but I guessed it depended on the behaviour of the engine, cache and maybe optimiser, and know/knew I don't know enough... My thinking: for dynamically linked files, one speed optimisation is to load the file before it's needed, at the expense of memory, while continuing execution of the loaded portions. It's easy to do if the filename is static. The code may never be executed, but still takes up space. Some data structures can also be pre-loaded in this way. 



Are included files ever unloaded? For instance if I had 3 include
files
and no loops, once execution had passed from the first include file to
the second, the engine might be able to unload the first file. Or at
least the code, if not the data.


I doubt that the code is unloaded -- What if you called a function
from the first file while you were in the second?
I agree it's unlikely, but it's feasible if coded is loaded whenever required. Especially if data and code are separated by the engine, and that's quite likely because of the garbage collection. 


Thirdly, I understand that when a request arrives, the script it
requests is compiled before execution. Now suppose a second request
arrives for the same script, from a different requester, am I right in
assuming that the uncompiled form is loaded? I.e the script is
tokenized
for each request, and the compiled version is not loaded unless you
have
engine level caching installed - e.g. MMCache or Zend Optimiser.


You are correct.

The Caching systems such as Zend Cache (not the Optimizer), MMCache,
APC, etc are expressly designed to store the tokenized version of the
PHP script to be executed.

Note that their REAL performance savings is actually in loading from
the hard drive into RAM, not actually the PHP tokenization.

Skipping a hard drive seek and read is probably at least 95% of the
savings, even in the longest real-world scripts.

The tokenizer/compiler thingie is basically easy chump change they
didn't want to leave on the table, rather than the bulk of the
performance "win".

I'm sure somebody out there has perfectly reasonable million-line PHP
script for a valid reason that the tokenization is more than 5% of the
savings, but that's going to be a real rarity.
Thanks - that's really useful - I didn't realise that the bulk of the saving wasn't in tokenising. 
Fourthly, am I right in understanding that scripts do NOT share
memory,
even for the portions that are simply instructions? That is, when the
second request arrives, the script is loaded again in full. (As
opposed
to each request sharing the executed/compiled code, but holding data
separately.)


Yes, without a cache, each HTTP request will load a "different" script.
Do you know if, when a cache is used, whether requests in the same thread use the same in-memory object. I.e. Is the script persistent in the thread? 


Fifthly, if a script takes 4MB, given point 4, does the webserver
demand
8MB if it is simultaneously servicing 2 requests?


If you have a PHP script that is 4M in length, you've done something
horribly wrong. :-)
Sort of. I'm using Drupal with lots of modules loaded. PHP memory_limit is set to 20MB, and at times 20MB is used. I think that works per request. All the evidence points to that. So 10 concurrent requests, which is not unrealistic, it could use 400MB + webserver overhead. And I still want to combine it with another bit of software that will use 10 to 15MB per request. It's time to think about memory usage and whether there are any strategies to disengage memory usage from request rate. 



Of course, if it loads a 4M image file, then, yes, 2 at once needs 8M
etc.


Lastly, are there differences in these behaviors for PHP4 and PHP5?


I doubt it.

I think APC is maybe going to be installed by default in PHP6 or
something like that, but I dunno if it will be "on" by default or
not...

At any rate, not from 4 to 5.



Thanks.


Note that if you NEED a monster body of code to be resident, you can
prototype it in simple PHP, port it to C, and have it be a PHP
extension.

A good idea, but not feasible in this situation.

Thank you.

Jeff


This should be relatively easy to do, if you plan fairly carefully.

If a village idiot like me can write a PHP extension (albeit a
dirt-simple one) then anybody can. :-)

Drupal tends to use about 10 MB of memory in normal usage for a reasonable set 
of modules in my experience, but a crapload more on the admin/modules page 
because it has to load everything in order to do so.  Normally you won't hit 
that page very often. :-)

However, Drupal is deliberately friendly toward APC.  I don't recall the stats 
(I know someone made some pretty graphs at one point, but I can't find them), 
but simply throwing APC at Drupal should give you a hefty hefty performance 
boost.  I believe APC does cache-one-run-many, so the code, at least, will 
only be stored in RAM once rather than n times.  (Richard is correct, though, 
that data is generally larger than code in most apps.)

Also, search the Drupal forums for something called "Split mode".  It was 
something chx was putting together a while back.  I don't know what it's 
status is, but he claimed to get a nice performance boost out of it.

Cheers.

Interesting.  If PHP tokenization is such a small cost, what makes a
special caching system better than the OS for caching files in memory
after the first disk read?

APC actually executes the opcodes directly in shared memory, so unlike a
disk cache, you are not copying lots of stuff around.  APC does need to
copy some things down into process-local memory, but most can be left
where it is.  Disk caches also tend to expire pretty fast because
everything your OS does tends to touch the disk and when you application
starts eating memory your disk cache is the first to go when things get
tight.  With a dedicated shared memory segment that won't happen.
Things will stay put.

It is also possible to run APC in no-stat mode which means it will never
touch the disk at all.  If you are on an Intel cpu with an older OS like
freebsd4, disk-touching syscalls are massively slow and you can gain a
lot by skipping the up-to-date stat check on each request and include file.

Finally the compiler does more than just tokenize your script.  It will
cache functions and classes when it can and rewrite the opcodes so these
functions and classes won't have to be created at execution time.  Of
course, that assumes you haven't gone all framework-crazy and made
everything dynamic with autoload or weird conditional function and class
declarations.  If it becomes a runtime decision whether class or a
function is declared, or heaven forbid, the same class takes on
different signatures based on some runtime condition, then there isn't
much the compiler can do to speed that up.

As a follow-up, since several people have asked:

We are looking for permanent legal US residents only, and primarily for
people that can work on-site rather than telecommute.  We are open to
hearing from off-site people who can consult for future reference,
however.

--- Begin Message --- I have to get a temporary server in place under a tight time frame and am using a pre-existing server that wasn't configured really for hosting websites. 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 
collect2: ld returned 1 exit status
make: *** [libphp4.la] Error 1
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!

Looks like mcrypt has an extra dependency.
Do you have the mcrypt-dev or mcrypt-devel package installed (whatever suse calls it) ?
When I just went to install mcrypt on my debian machine it added "libltdl3" to the list of packages it needed. 

Do you have that one installed?
How come you're compiling and not installing the package(s) ? Is suse too old to be able to install 4.4.2?
Last question :P how come you're installing 4.4.2 and not the latest - 4.4.4 ?

Hi,
A client has requested a cart with the following features, any leads on such a package, preferably open-source? 



Is there a way to add things like:

•Customer ratings to the cart?

•Qualifying criteria:

Is there a way to add that to the cart as a
checkbox with descriptor? For example, if someone's selling a monitor that's 
made with no toxic materials and 50% recycled plastic, the administrator
would check a box that says "no toxic" and another that says "recycled" and 
then add a descriptor for the recycled button that gives the amount of
recycled content?

•Data for accounting purposes:

(sales info and the like). I'd like to
collect customer info for internal purposes, or
if they opt-in, for further communication. I'd
like to get the usual web traffic stats
(referring sites, etc.).


Return True,

While we're talking about optimization, I'd want to check to make sure COUNT(*) didn't ask MySQL to generate a throw-away recordset consisting of all fields. I wonder if it would be more machine-efficient to use COUNT(`last_name`), specifying a single field, in this case the same field your query is examining anyway.
If the fields mentioned in the where clause are keys or if there is no where clause, a count(*) uses the index trees to make the count, it won't even access the data racords at all. Moreover, it won't even read the whole index tree node, just the header record of the block that indicates how many key records that block contains. I don't really know about MySql or any database engine, but these are techniques well known in the trade.
On the count(fieldname) issue, it is different from a count(*) and may give different results. When you mentione a field it will only count records where that field is not null. Select count(fieldname) from table is the same as doing a select count(*) from table where fieldname is not null. It will take just as longer as processing any additional where clause.
