Still, with fs_usage PID, I get more the 57k lines of stuff... I've found

Which tells my that my last asumption is right, it's file-system related.
The process passes it's time at :
- System busy and idle tasks for 6 seconds
- read for 4.8 seconds
- getdirentries for 2.2 seconds
- httpd usermod (I assume that is php processing time, nothing wrong here)
Since I am a registered Apple developper I will log an incident with apple
for this. I'll let you all know
And Richard, I must rule out the mysql problem. As stated before, on two
hardware identical machine, one with 10.3, and one with 10.4. The mysql
database is on a third different machine. So connection time should be
identical. Besides, with the trace i've done with micro-seconds timestamps,
the majority of the time mysql_connect takes less than 0.01 seconds.
As for includes, again as stated before, all is the same, including config
files, thus include_path, wich only contains /usr/local/lib/php, and this
directory contains the base PEAR installed over time plus one or two other
file.

You certainly wouldn't want to do just fs_usage. Typing something like
"fs_usage httpd" will show you just what the httpd process is accessing.
Read the man pages for other options that may be helpful.
I've got a few things running on OSX 10.4, although none that handle lots
of traffic. Public sites:
dutchessfootball.com - a football pool, the picks page is the slowest to
load. That's on a single cpu 1.25 G4 512MB RAM
heardthroughthegrapevine.com - wine tasting site, nothing fancy or that
complicated. That's on a 400Mhz G4 384MB RAM.
The big application is internal to my company and has about 285 "web"
files total, and about 45 mysql tables (contacts, companies, resumes
invoices, jobs, emails, journal,etc). They all have lots of includes
since I use a custom templating system to separate php from html. I do
not use PEAR or any content management system, I found them too slow. I
know a few people who have looked at Mambo and rejected it because of
it's CPU load, although they were all using Windows servers. I've never
looked into why Mambo has high CPU requirements.
Is it just the Mambo parts you are having problems with or is it php in
general?
With 100% CPU, we've narrowed it down to something there. Now we need to
figure out why the CPU is the bottleneck.

I think you can use a different handle when using fwrite() which will
make php create a file if one is not already there: something like
if ($fp = fopen($file,"x+")){
echo"opened";
}
fwrite($fp,$content);
fclose($fp);

You need to open the file before you can write to it, you do that using
fopen(). You can choose to create a file or modify an existing on by
using the fopen mode flags. The different flags are outlined in the
documentation, I think you will be wanting to use 'w'.

Angelo,
Does the content in the db contain HTML tags? If so you may need use
addslashes(), stripslashes(), htmlentities() and the like as you save and
retrieve content.
All you really have to do is generate any HTML to start the page, add your
content, and then closing tags and echo() or print() the whole shooting match.
You could do this with a function called CurrentIssue(). Within the
function, as you build the HTML, concatenate it to the function's internal
return variable.
Then you could simply echo CurrentIssue ;
Why do you have to generate an HTML file?

Not sure how this might work in PHP, but there is something called WSH
(go to MS and poke around) that gives you access to a ton of really
interesting Windows bits and pieces. The following is a script I run in
Lotus Notes (LotusScript is rather like VBA) and it allows you to set
the default printer to something which you then just print to and reset
the default to whatever it was. PDFCreator is a 'printer' that
generates PDF files (you probably don't want this since use of
PDFCreator includes it's own set of user interactions but the WSH
concept may still work).
Warning - I'm not a WSH expert and I never figured out how to properly
reset the printer to the user's default so I don't actually use this
script. Still, someone smarter than me may have the magic touch - give
it a whirl.
Sub Initialize
Dim net
pName$ = "PDFCreator"
Set net = CreateObject("WScript.Network")
net.SetDefaultPrinter pName$
End Sub

Subject: Re: [PHP] PDF printing under windows.
Two (and a half) things:
1. Even though DOS/Windows machines don't have, specifically,
/dev/printer or /dev/lpr or whatever the *nix specific is, it does have
a LPTx: device
According to the page listed below, it may be possible to do:
copy /b filename LPTx
The /b indicates it's a binary file. How it'd handle PDF fonts and
such, I'm not sure, but I know that some printers can decode PDF's
internally so that'd work out great.
2. Second point... If all you need is a simple print function and you
have exec() privs, why not try to find a DOS based printing solution.
The copy command above was mentioned on this page:
http://www.lerup.com/printfile/
It says it works with Windows 3.1 to XP. And it even works with command
line options:
"PrintFile also works well with command line (DOS) programs. It has
several command line options and can read data from command line
standard input, e.g. a command line pipe. A command like:
dir | prfile32"
So I guess it sets up it's own print device that you can pipe to.
And finally... the half a point. All of this may not be necessary
because you can configure Windows printers to support DOS (although I
havn't done this in ages, I assume you still can in XP) so in theory the
normal DOS "print" command would pipe through Windows drivers and print
handling to the printer of choice.
So in general, there's probably zero need to use COM to print. One of
these options should pipe the file through Windows which in turn, could
possibly send it through the proper printing method. If not, you might
be able to look in your registry and find the right-click "Print..."
option and see if it's something you can execute from command line.
Ok, I know this email's too long already, but I know someone's going to
say "How do you do that?" So here's the 50 cent tour:
1. Pull up "regedit"
2. Search for the file extension ".pdf"
3. Make note of the "(Default)" value, in this case "AcroExch.Document"
(I think this is specific to having the full Acrobat installed) 3. Below
the area where all the file extensions are in HKEY_CLASSES_ROOT there
are the actual named app section (that way, ".gif" and ".jpg" can both
point to Photoshop.document" or something.. get it?) So search for
"AcroExch.Document" in this case 4. Expand that tree and look for
"shell". These are all the things that show up on your right-click menu.
In this case, we have a "print" section. Under each of these entries,
there should be (but sometimes not) a "command" branch. This is what's
run when you select that option from the right-click menu. And voila!
We find that the command to use Acrobat to print (which can be executed
from command line on a Windows machine) is:
"C:\Program Files\Adobe\Acrobat 5.0\Acrobat\Acrobat.exe" /p /h "%1"
Substituting the %1 for the filename.
Using that command line in a php exec() call should exactly simulate
selecting right-click PRINT on a PDF file.
Crossposting this to PHP-Win for their benefit too since this is more
Windows related than PHP General.
I see lots of ways to potentially solve this problem without using COM.
I loved messing with COM (with or without PHP) for a while, but it's not
a great general solution to things unless you absolutely HAVE to control
the app (which is very cool and slick sometimes, but not for something
as simple as printing).
Hope this gives you some new avenues to persue. Best of luck!

OpenOffiice it wants to play with PHP and COM.
I have tried to exec print on the windows box but that just hung.

The problem there is that you end up having a load of acrobat.exe's

automate printing of invoices maynot be a good idea :-)
I think I'll just install a linux box and use CUPS :-)

This is really dumb and overly simple, which is probably why it was missed/not
brought up, but it just occurred to me that, assuming you have a browser-based
interface to your app, why don't you just send the PDF to the browser for
printing? Then it should use the Acrobat Reader plugin to open the app then
just have the user (you?) click the print button? Or do you want it totally
one-button click and that's it?
Just a thought.

cURL doesn't really interact with the browser directly here...
Your script is the "middle-man" between their form and FMSRegister.php
But they didn't surf to FMSRegister.php
Your script surfed there, but their browser didn't.
If you want their browser to surf there, you have to send "Location: "
headers, and you'd need to include whatever GET parameters you could
to make the request come out like you want, but, at that point,
there's not much reason for cURL to be involved...
I suspect you've over-estimated what cURL can do and what it's for...
All it does is let a program pretend to be a browser.
It doesn't let your program take over control of the user's browser.

I wanted to avoid using GET as I did not want the information to be in the
URL. I figured that if my processing script (curltest.php in this example)
determined that the data submitted in the form FMSRegister was faulty,
according to my rules for processing the form, that I could have the
processing script invoke curl to post the current data back to the form for
display to the user. I am half-way there. Perhaps the file name change is
moot, but I thought that it would be a nifty technique as it allowed me to
keep processing seperate from the form itself.

It may not be, but it was a thought. As they say, there is more than one way

curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_URL, $url);
curl_exec($ch);
curl_close($ch);
Now, this works OK...save for one little problem that I cannot seem to
figure out. The URL now reads
http://TEST20051010/NameOfProcessingScript.php instead of
FMSRegister.php.
I am searching the curl options http://www.php.net/curl_setopt but have not
found what I am looking for. Can someone clue me in?
Thanks!
Here is how I do what it sounds like you want to do.
Simply serialize your POST array, i.e., $saved_post= serialize($_post)and save it [a file or session buffer, whatever]
if you are instigating a new page; if not, you have the post array saved.
Then when you want to repopulate the form, simply unserialize($saved_post) and fill in your <inputs..> etc. from the
array.

Sorry, I do not know, what you mean be using "ICQ account numbers"
because it works like this, but since some time ICQ limit the
number of messages sended by an account.

It limit the number of messages send in ONE minute.
AFAIK it is limited to 16.

There is some discussion here you may find useful:

If you already have a database connection you can simply use a
sequence (or auto_increment in MySQL)
But that assumes you are willing to have predictable IDs, which you
might not.
> Can anyone recommend a way for solving this trouble?
You could use md5() and track every ID you hand out in a UNIQUE column
in a db, and simply generate another random md5() if you happen to run
into a duplicate.
The probability that you'd generate too many duplicate random md5()s
in a row for performance to be an issue is pretty small, if you
already have database activity going on.

The above function could generate much more than millions of unique IDs.
You have 1.46 x 10^48 possible hashes, and with an input of the current
time in microseconds prefixed by a Mersenne Twister random number and
suffixed by additional entropy from the combined linear congruential
generator, collisions should be *very* improbable, even when generating
IDs on multiple hosts all at the same time.

Something to consider:
What if, in Yahoo, the SECOND exact same email is tagged as spam
BECAUSE it is a duplicate.
Change up the email subject and body significantly to test this.

You'll never truly know what Yahoo's spam-filtering algorithm is.
You have to live with the fact that some percentage of "real" email
will end up in Bulk, and some percentage of junk will get through into
INBOX.
Unless the user is allowed to whitelist specific addresses or domains,
that's just how it is.

hi,
i'm not a regex guru myself, but the following regex should work - tabke
a look at my regex test setup ...
<?php
$test = array(
"1",
"1.",
"1.2",
"1.23",
"1.234",
"1234",
"1234.",
"1234.5",
"1234.56",
"1234.567"
);
// if there's a dot, we want at least one number after it.
$regex = '/^\d+(.\d{1,2})?$/';
// test all or numbers ...
foreach ($test as $number) {
if (preg_match($regex, $number)) {
echo "ok ";
} else {
echo "no ";
}
echo $number . "<br />\n";
}
?>
i don't think there's a difference between \d and [0-9], but again, i am
no expert ...
regards,
phillip

It would be better to escape the point, cause the point greps for everything.
$regex = '/^\d+(\.\d{1,2})?$/';
Without escaping the point, it could match for '1234:567' or something else.

Escape the decimal point.
$regex = '/^\d+(\.\d{1,2})?$/';

I kinda' solved this, but not really....it was more of a mental adjustment.
FMSRegister.php <---- registration form
FMSProc.php <---- central processing script
If the registration form is incomplete I use cURL to post the data and form
to the user even if the name of the file is not the same. I could call the
central processing script (which acts on application items in a switch
statement) something clever since it is being presented back to the user,
but since this is for an internal application I probably will not bother. It
would be neat if cURL could essentially post an interface back to the
browser....but I do understand the complications. A search has yielded
several who have basically asked the same question as I have though.
Now, I know that this may have some to do with laziness on my part, but it
was mostly an experiment.

I'm having a major problem with what seems, on it's face, to be a
really basic array function.
What happens is on the browser end, I've written some javascript code
that packages up javascript variables in native PHP format and sends
the packed variables to a PHP script on the server via a POST and
XMLHTTP. On the server end, the PHP script grabs the packed variables
out of the $_POST, strips slashes and uses the "unserialize" command.
Here's the function that gets the post data
$unpacked_data = GetDataFromPOST();
And here's a var_dump of $unpacked_data as it appears in the browser
array(1) { ["handler"]=> array(1) { ["0"]=> string(9)
"databases" } }
I'm able to get the "handler with no problem like so:
$parts = $unpacked_data['handler'];
Which yields the following var_dump
array(1) { ["0"]=> string(9) "databases" }
Here's where the problem starts. I've had no luck whatsoever trying
to get items of $parts. I've tried all of the following and each of
them return NULL
$part_1 = $parts[0];
$part_1 = $parts['0'];
$part_1 = $parts["0"];
$part_1 = $parts[48]; <- ASCII character for zero
In desperation, I also tried this
foreach($parts as $key => $value)
{
var_dump($key);
// => string(1) "0"
var_dump($value);
// => string(9) "databases"
$parts_1 = $parts[$key];
// => NULL;
}
But no luck
I also checked the type and size of the key like so
foreach($parts as $key => $value)
{
echo gettype($key);
// => string
echo sizeof($key);
// => 1
}
Anyone have any insights as to what the heck is going on here? This
should be a piece of cake but It's stopped me cold for a full day and
a half
Thanks for any help
Ken
