Re: [PHP] Question about apache-php concurrent process control

[Liang ZHONG]

Thank you Richard, I think I'd better explain a little about the project and 
then you or somebody else might give some good suggestion upon the 
restrictions of the project.



The project is to implement a digital library protocol, called oai_pmh 
(http://www.openarchives.org/OAI/openarchivesprotocol.html)
It acts as a broker for the harvester client to get meta data from libraries 
that have Z39.50 server. The database resides on libraries, and vary alot in 
speed, number of records, way to accept connection from z39.50 client. The 
number of records from some libraries might be over million. So the part 
that getting data from those libraries behave very differently.


The harvester client sends http request, normally through program, like perl 
LWP. It normally sets 180 time out for connection.


According to the protocol, the oai_pmh data provider act on respond to 
harvester http request, it begin to connect to specific library's z39.50 
server, get data in, write them to disk, and translate to another xml 
format, then send to harvester client. If the records are too many, oai_pmh 
should send back partial data with resumption token. The harvester can later 
send out http request with same url but with the resumption token as one of 
the POST variable to get further data records. This process can be 
continueing till all the records has been send.


Thus I noramlly use perl program to send the http request and get content 
instead of BROWSER. The behavior of buffer should not due to the setting of 
the browser.


I can not echo the metadata directly back, since xlst need to use to 
transform and new xml file(s) are writen. The header() redirction is very 
nature to use if it can close the connection before I do something very time 
consumming after that.


The exec with & and the cron job are hard to use, since connection to z39.50 
with a lot of state variables like connection id, etc can not easily be 
passed to another script.


The harvester user normally is not a human with browser but a piece of code, 
while looping and sending out http requests if the page it gets back has 
 tag. (it replace the element between open and close tag of 
, append to the next http request as POST variable for next 
records page). But the problem is each http request posts a timeout of 180 
seconds.


Thus I have to return partical data within 3 minutes while the whole process 
might take hours or even days. Then the process continue to get data from 
library server and transform it, then write to disk in a particular 
directory. The next request with resumption token comes in, the program will 
check for the existing of the directory and return if yes. If not existing, 
program will check to return within 3 minutes or send back not available 
information.


Sorry for the long writting. I hope some one has some suggestion for me. 
Thank you very much.

Depending on the buffering options in php.ini and/or Apache, this may or
may not just end your program, as I understand it.

Once you send the Location header, everything else is irrelevant, or at
least not reliable.

You could do:
echo $result_of_do_A;
flush();

and the user will see what happened with A, while waiting for B.

If that is what you are seeing happen, you probably have output buffering
turned "on"

The Location: header is acted upon by the BROWSER, not by PHP, not by your
server.  The BROWSER sees that header and then jumps to somewhere else.

You could also look into the pcntl stuff to fork() or, depending on
various settings, you might get:
exec("do_B() &");

to get B to happen in the background.

With all that said:  As a general rule, when I found myself doing this
kind of stuff, I later realized that I hadn't really designed my
application very well for an end-user experience.

If it takes THAT long to finish B, then you're probably MUCH better off
putting something in a "ToDo List" in your database, and doing

Having just a few months ago spent a great deal of time finding a cell
phone that would just tell me my own long/lat where I was, without the
for-fee fancy directions or my non-existent boss tracking me features, I
ran into a fair amount of info in this topic, mostly by accident.

I also wanted an SSH client so I could do emergency surgery on websites if
needed.

You'd be AMAZED how hard it is to get a cell phone company to tell you if
it has these two features or not and on which models it actually worked...

[I got the Nextel + Blackberry 7250 and it has them.  YMMV]

There are at least two distinct systems in different cell phones:
1. Cell Tower location
2. GPS location

I'm not sure #1 can use multiple signals and triangulate or not.  Even so,
it ain't gonna be real reliable in the case that you want to know EXACTLY
where somebody's cell phone is in case of an emergency...

#2 works better the more GPS satellites it can find.
I've seen results with 5 satellites and an error margin of 3 meters, as I
recall.  (Maybe that was 4 satellites?  Definitely 3 meters, though)

Some phones have both #1 and #2 and use #1 as fall-back.

US Cell Phone companies were required by law to have 911 calls provide
caller location by [some past date] to 911 operators.

Every one of these companies filed for, and received, an extension of that
deadline.

All the filings had different extended deadlines, as they all filed the
paperwork at varying times with varying reasons why they were not going to
make deadline.

So, in short, nobody knows when they'll actually get the damn things to
work right for 911.

The idea that you could arbitrarily track your friend's phone is, at best,
a Privacy Nightmare...

But let's assume your friend somehow can "sign off" or provide consent for
you to receive the data you desire, or wants to take some action every day
to tell you where they are, or even wants to program their phone to do it
automatically...

If he/she/it has a fancy enough cell phone with working GPS and/or Tower
location system, and if that phone allows the installation of new
applications, then, in theory, there could be an application "out there"
that would automatically surf to some URL to report their location.

Otherwise, you can just give them a form on a website to surf to and let
them tell you where they are, or maybe they could use their cell phone as
a PHONE and call you to tell you where they are or...  Well, you get the
picture.

I don't think anybody has written that automated location notifier
application yet, EXCEPT the guys who will charge your $40 a month to track
your employees' cell phones, which allegedly *IS* an available service for
some cell phones with some providers...

Though I believe I heard at least one person state that this was still in
the vaporware stage of development as far as the end user is concerned --
That there were still some bugs to work out and while they were "close" to
having it work reliably, it wasn't "working" yet.

If you did write such an application it would probably be in Java or Palm
OS or ... Well, it almost for sure will *NOT* be in PHP, since, as far as
I know, PHP is not installed on any commercially sold phones.  Though I
think there was a Linux-based Palm-like device that might maybe have had
PHP working on it...

This was all the state of things several months ago, far as I could tell,
and I'm probably already horribly out of date.

Floating point mathematics is inherently "unreliable" in computers.

Consider, for example, 1/3 in decimal notation:

1.33...

PHP can only write so many digits down in a 32-bit floating point
representation, just as you can only write down so many digits before your
hand cramps up or you run out of paper or you get lazy and put "..." on
the end. :-)

Now, the thing to remember is, the problem won't appear where you expect
it to from your experience with DECIMAL numbers all your life because
floating point numbers are being stored in a binary/hexidecimal notation.

If you are feeling particularly masochistic, you can Google for "floating
point internal representation mantissa exponent" and you're gonna find out
EXACTLY how those numbers get stored.  Set aside a good chunk of time to
absorb it all... :-)

Even something as simple as:


could, in theory, print out something like:
1.
and be "correct" as far as Computer Science is concerned.

If you need PRECISE mathematics, you should use integer and count pennies
instead of dollars -- or even 1/10th of pennies or whatever resolution you
need.

Of course, every step you take on the right, you can only store 1/10th as
large a number of dollars as your maximum amount.  But you are starting
with 2 billion as your max, so that's a lot of room to play with.

If you *need* float numbers and precision out to decimal point N, look
into BC_MATH and that new-fangled Math package PHP has for this very
reason. You'll still be dealing with this issue, but you'll know your
numbers are accurate to the Nth decimal point, and it will be painfully
obvious in your code that it is so.  [It will also be SLOWER than just
plain float numbers.]

If you just don't care about the damn penny, but want your code to work,
something like:

if (1.00 <= $x && $x <= 1.01){
  // $x == 1, really
}
may suffice for your everyday work-a-day computing needs...

Though that can also turn into a lot more problems than you think, down
the line...

Remember 2nd Grade when long division was "tricky"?  Yeah, well, computers
are a hell of a lot more stupid than 2nd Graders, any day of the week.

Note that there *ARE* computer languages where are prefectly happy to work
in fractions (Lisp is one such language) because somebody has programmed
the algebraic rules of fraction arithmetic into the language:
(let ((x 1/3)
  (y 2/3))
  (print (+ x y))
will cheefully and with 100% accuracy print out "1" every single time.
[Apologies to Guy Steele if my 10-years-unused Lisp syntax is not spot on.]

Lisp stores fractions as 2 integers, not as floating point numbers.
[Though of course you can ask it to convert and round off if you like.]

You could, if you so desired, whip up a PHP "class fraction {" code-base,
or even just store fractions as 2-element arrays (numerator, denominator)
and write some procedural functions to work with them.

It's not exactly Rocket Science to do that.

I dunno what his Send script looks like, but that 12 isn't a 12 at all.

It's a 1 with a > symbol and then a 2.

The > symbol probably got eaten by somebody's email program somewhere
along the way.

See, in some Linux/Un*x shells (errr, like DOS prompt only not broken)
there is the idea of "standard output" which is where your basic output
messages go.

There is also "standard error" where your ERROR messages go.

On Linux/Unix file systems, stdout (standard output) is bound to a
"special" file which lives in /dev/1 -- it's not really really a file, but
a "device" but to send stuff to the "standard output" -- which is
generally your screen, you can just write it to /dev/1 and it gets there.

For shorthand, in shell scripts, you can just use "1" to mean "/dev/1"

Similarly, "standard error" is "/dev/2" and you can use "2"

So, what he really had was 1>2 which was saying:
Take anything that was supposed to go to 1 (standard output) and send it
(the > symbol) into 2 (standard error)

So he's telling the shell (operating system) to combine any normal output
into the error output so it's one big mess of output.

You can learn more about this stuff (though it may be a bit overwhelming
at first) by searching for "man bash" or reading an introductory Linux
textbook or resource on-line.

Browser technology has advanced a bit since then.  Today we are no
longer dealing with a pseudo-SGML hack called HTML like we were 10 years
ago.  Today's web browser is a DOM Tree viewer.  In Firefox you can
click on Tools->DOM Inspector and click through the tree of the page you
are on.

The language to manipulate this DOM Tree is Javascript.  And yes,
Javascript gets this DOM manipulation right, because it is so closely
integrated with the actual parsing of the tree.  If it didn't work, the
browser wouldn't work either.  For example, take this JS:

   foo = document.getElementById('some_id').value;

This obviously gets the value of the field with some_id.  This prods the
same DOM tree with the same code that the browser itself uses when it
wants to know what the value is in a given element of the tree.  So at
this level Javascript is fine, and yes, you can count on it working in
all modern browsers.  If any of them can't do this, they won't be around
long.

It gets a bit dicier when you try to extend out beyond simple document
manipulation, but that is really no different than trying to push the
boundaries of CSS or trying to get IE to speak CSS2.  The bar keeps
getting raised.  In my opinion it has been raised well above basic
Javascript for quite a while now.

He wants a function that, if you put in $x, you get out 'x'

For *ANY* $variable.

There is no such function.

Usually the person asking it is doing something very newbie-ish, and very
wrong.

I know, cuz I was that person, many many years ago. :-)

I think what I needed that time was "variable variables"...

The other thing that tends to bring up this question is somebody trying to
write a custom error handler, not knowing about
http://php.net/trigger_error and friends.  Though that only gets you the
line number and filename where the error occured, not a specific variable
name.

If for some reason one *NEEDS* to have "names" and variables and to know
what a variable's "name" is, you *probably* want to use an associative
array and use the "keys" as your names.

Hopefully this is helpful to the Original Poster, or somebody some day.

PS

It's true that your variable could/would/should appear in debug_backtrace,
but how would you pick it out from all the other variables that would
appear in your debug_backtrace?

For that matter, it's in $_GLOBALS, but how would you pick it out?

You could print out all variables that were equal to your variable, and

WILD GUESSES!!!

There might be a CURLOPT_CHARSET or similar constant that is not
documented on php.net, and that might not have made it into PHP as a
constant even, but if you read the original curl docs will tell you how to
do it...

You might have to do something like:
if (!defined('CURLOPT_CHARSET')) define('CURLOPT_CHARSET', 47);
just to have the constant available.


It's also entirely possible that curl, by default, sends some kind of
default "Accepts: charset=ISO-8859-1" header or something similar, and you
just need to send some *other* header to tell the web-server that your
browser "understands" UTF-8.  Or maybe even that you specifically want the
results in Chinese or whatever...  I know a lot of webservers/browsers
don't implement the language-preference for the browser/user, but *MAYBE*
it will have some effect.

Just some ideas from a guy who knows he's WAY too stupid to ever have
multi-lingual anything working on his own web-site. :-)

There are innumerable other HTTP servers.

Some of them support PHP (and vice versa) to varying degrees.

I know there were posts about at least *ONE* of them I recall I wanted to
try "some day" and I'm pretty sure it was because that server gave you
more control over the PHP User.

Now, what the name of that server was, I have NO IDEA...

It was probably about 2 or 3 years ago.

I vaguely recall the name was maybe somehow related to "dragon" ???

At any rate:  The web-servers PHP supports officially is pretty short, and
you should check those out.

There are probably a bunch MORE web-servers that claim to work "just fine"
with PHP -- but possibly only as CGI, at which point suexec and the
faithful standard Apache is probably a better idea anyway, unless you have
more reasons not yet posted for dis-liking Apache.

I don't think Apache really loads *that* much stuff in if you set yourself
the goal of paring down your httpd.conf to the features you NEED.

Recursive function that will check arrays and return references to the
empty keys. Then, you can do whatever you like.

If you need something simpler, do

8<-
if( in_array( $workingArray, null ) ) {
// Do something
}
8<-

Same goes for 0, '', etc.

Good luck!

What I was thinking with debug_backtrace() is that you could get the 
information for the function that called the function you want the 
variable name for, *reducing* the likelyhood of duplicate values, but 
admitedly not eliminating it.


You could also pass the name of the variable to the function:

someFunction($foo, $varName=""){ print $varName; }

call it with -> someFunction($bar, 'bar');

That would definately get you what you want, but again it would be messy

This cannot be true for many versions of IE...

I would have noticed. :-)

Though IE *is* giving me fits on this page:
http://uncommonground.com/artist/

They "login" okay, but can't get to following pages.

These are users for whom the question: "what browser version do you
have?"
yields answers like "Windows 2000"...

Is it that goofy mini privacy policy crap?  Like the bad guys won't just
LIE.

[PHP] Remote HTM not printing via PHP

[Chirantan Ghosh]

Sorry Guys for the previous ignorant Q I thought I was emailing the Help desk, 
do forgive.


I am trying to print a remote header menu in a html page without frames.

The client side JS in located in this htm. ( 
http://www.dtcc.com/ThoughtLeadership/menu.htm )

I tried both INCLUDE, REQUIRE  with no avail. I am  a complete novice beginner 
so can anyone help me a bit please?

The code I tried:
==




  

 http://www.dtcc.com/ThoughtLeadership/menu.htm';
print getRandomLine($filename);

function getRandomLine($filename) 
{
global $errors;

  if (file_exists($filename)) {

mt_srand ((double) microtime() * 100);
$lines = file($filename);

$line_number = mt_rand(0,sizeof($lines)-1);
return $lines[$line_number];

  } else {
$errors['getRandomLine'][] = "File: $filename not found";
return FALSE;
  }
}
  ?>

  
  
 

...& On it Goes



Can you please let me know why can't print the remote HTM  in the current page 
(Though it is in a different domain)?

Thanks,

Chirantan

If your PHP script is on the same drive as the GTK lib, then you can use
phpinfo() to find out the variable name that has your drive letter.

Something like $script_filename or somesuch.

Insert the USB device, note the drive letter, run php -i | grep "X:"

Course, on a Mac or Linux box, your USB device won't have a drive "letter"
per se -- You'll have the correct PATH though, for the OS it's on, which
is far far more portable.



Sorry that doesn't work, just in case i tried erasing anything related 
to Apache, PHP and Perl on my home system. It seems by default, if PHP 
can't find a php.ini it sets all defaults to c:\windows instead of 
setting them to the current application run path.


I think my next step will be to check if i can recompile PHP manually 
for windows and change the code in it to reflect what i need in terms of 
defaults... Like using the application start path and stuff like that to 
load extensions and more.


Does that look like a good idea?

Just out of curiosity, why are you just printing a random line from the 
file?


Then the next question is do you have your error reporting turned up:

error_reporting(E_ALL);

and display_errors = On in php.ini, only for a development server, or at 
least a log file to look at, for a production server?


I'm going to assume that you've checked the source of your script output 
and the random line isn't where you thout it would be?


The best thing to do would be to just print out the lines/files you are 
trying to get, without the rest of the HTML, to see what your getting 
from just the part your having trouble with.

The OP indicated s/he *was* setting Content-Type.

They were also sending Content-Disposition in order to indicate the
suggested filename -- and wanted to alternately either send the filename
*or* have the content echoed to the screen. The 'solution' was to use
different URLs, and set Content-Disposition to either 'attachment' or
'inline', respectively.

Because the page is generated by a couple of PHP scripts and
ONLY THIS PAGE is not working.

So I was thinking there is a problem with the file-extension
*.php and Konqueror can not handel this... (It is KDE 3.4)

Hi Edward,

I would simply like to print the remote Menu page( 
http://www.dtcc.com/ThoughtLeadership/menu.htm ) in a new page.
I did the Error report print because I had no idea for what reason my PHP 
code was working.


The menu is used  as a header as well(the root file is JS which I can't use 
as I don't know all the directories  of dtcc.com )
I am simply trying to impress a non technical person of the company so I can 
get a design contract.


How can print the menu in different domain html pages? ( I would like to use 
PHP as server  language)


Thanks,
Chirantan

Konqueror cares not for your extension, it cares for what the data itself is.  
If you've got buggy javascript or similar, you should see a red bug in the 
bottom right.

The file extension is irrelevant.  This is not a php problem.  More than 
likely you have an error in what you're outputing to the browser; 
JavaScript if I was a betting man.

Getting the code from the remote site is easy enough, you just gotto find

that should get you the basic code including the javascript:

echo $filename;

once you have the code, start converting the relative image paths to full

should work.

Hey,
The problem might be with your php settings,
run phpinfo() and see if allow_url_fopen is set to ON

heres where i uploaded what i did so far, little more needs to be done
so that the mouseover images work:
http://php-php.com/a2ztips/test.php

The way I did it is in a *very very very dirty way*, I suggest you dump my
code and use a RegEx there (am too lazy to write one) instead of the
multiple
str_replace calls but my code should give you a good starting point.


http://www.dtcc.com/ThoughtLeadership/menu.htm');
$filename= str_replace("../dtcc.css","http://www.dtcc.com/dtcc.css";,
$filename);
$filename= str_replace("images/","http://www.dtcc.com/images/";, $filename);
$filename= str_replace("/http:","http:", $filename);
$filename= str_replace("..http:","http:", $filename);

echo $filename;
?>

Cheers,
Ryan

First try this:

print 
htmlentities(file_get_contents('http://www.dtcc.com/ThoughtLeadership/menu.htm'));


?>

That will let you see the HTML in your browser. If you don't get 
anything then either your request is being blocked by a firewall or you 
don't have fopen wrappers enabled. I'm betting on the latter though.


Are you running a local install of php or through a remote server? You 
should be generating some kind of errors if your not getting anything back.

You would still have to replace the links to the full path instead of the
relative path that it now has.
The str_replace calls are kinda expensive IMHO, a good regex would be better
(like I said in my last mail)
another thing to note is sometimes the remote server times out or is too
slow so the script times out...

I hope this helped dude...will take down the page from there in a few hours.

The easiest way to fix this is to validate your output. Konqueror is

First try this:

print 
htmlentities(file_get_contents('http://www.dtcc.com/ThoughtLeadership/menu.htm'));


?>

That will let you see the HTML in your browser. If you don't get anything 
then either your request is being blocked by a firewall or you don't have 
fopen wrappers enabled. I'm betting on the latter though.


Are you running a local install of php or through a remote server? You 
should be generating some kind of errors if your not getting anything 
back.

I never claimed, what I was doing was correct, rather I didn't knew well
enough that 'PHP is not C++', and I was misunderstanding how reference and
global variables work in PHP.

I don't think it will make the code confusing, but the person looking at the
code should understand how reference and global variables work. Using
reference variables avoids unnecessary extra copying of objects, and while
using large arrays it can make a big difference in speed. 

The lesson to learn from this thread is that variables declared in a function
as global (using global keyword) are new reference variables to the actual
global variable. And, so when these global variables in functions are assigned
a new reference, it breaks the old reference and makes them refer to the new
location, and the actual global variable is not affected. 
But in contrast, if the global variables in the function are assigned a new
value, this does changes the value of the variable in the outer global scope.

Well if you called someFunction('bar');

Function someFunction($myVar)
{
global $$myVar;
echo "the variable name is '$myVar' and has the value of ".$$myVar;
}

But that relies on the global and is also a bit messy in a recursive
situation.

Actually it's not either...

Since you can't easily debug when generating XML, as malformed XML will STB,
I have this function which dumps out an array and recursively sub arrays.

It would be very useful to dump out the name of the variable as part of
this, as a lot of text is on the screen with all the tags and such. 

It always annoyed me about print_r() that it doesn't tell you the variable
name either, so you have to always prefix it with an echo/print just above
the print_r.

/**
* Print out an array in XML form (useful for debugging)
* @access   public
* @paramstring $myArray the array to output in XML format
* @version  1.0
* @date 07/19/05
* @todo It would be nice if we could extract the array's variable
name and output that as an attribute
*/
function print_r_xml($myArray)
{
print xmltag('ARRAY', null, 1);
foreach($myArray as $k => $v)
{
if (is_array($v))
print_r_xml($v);
else
print xmltag($k,htmlspecialchars($v));
}
print xmltag('ARRAY', null, 2);
}

/**

Since it's a remote server, it's quite lilely that they've disabled 
fopen wrappers. It can be a security concern for hosting providers. All 
you can do is ask them if they allow it, they should be able to tell you 
but I really doubt that they do.


You can check what they have configured php for by running this in a page:



That should give you a pretty page with a lot of information about what 
is available for you to run through php.


Good luck!

[PHP] On register_shutdown_function: What might be the problem?

[Liang ZHONG]

When the time_limit is set to 0, the redirect page will be shown in 20 
second after the file ccc is created.
When the time_limit is set to 5, the redirect page will be shown in 5 second 
and the ccc file is not created. The error from curl command line tool is 
as:

---

Fatal error:  Maximum execution time of 5 seconds exceeded 
in/./y.php on line 6



What might be the problem that my register shudown function can not 
continuously run after the main program end?
What is the correct way to keep the function running after I redirect a 
existing page to http client and then  immediately close the connection?

Given it's a fatal error, it's as bad as a syntax error. It cancels
everything it's doing and leaves.

Remember that, even the shutdown function has to obey the time limit.

Re: [PHP] On register_shutdown_function: What might be the problem?

[Liang ZHONG]

I want the http client see the page ( here y.html) immediately after I call 
header function, and then close the connectiion, and the function f running 
in the background. But trying many  many times, the result seems that I have 
to either set the time limit to small to send the the html page sooner but 
also terminate the background running function which was registered as a 
shutdown function, or set the time to long enough for the shutdown function 
to finish while keeping the http client waiting until function return.


I doubt that register_shutdown_function meant to behave this way by its 
design. I would like to find out what could be wrong of my code, 
configuration of php or apache?


My Question is:
What is the correct way to keep the function running after I redirect an 
existing page to http client (which I want the client get immediately) and 
then immediately close the connection?


Thank you very much.

Use the execution functions to call an external script that performs the 
tasks you want performed. If you execute, for example, 
"/some/path/somescript &", then the exec() function will return 
immediately and somescript will continue to run.

The first number is the total uptime in seconds, the second number is
the total idle time.

Re: [PHP] On register_shutdown_function: What might be the problem?

[Liang ZHONG]

I think I did not express myself clearly.

What I want is to be able to redirect user an existing page (let them get it 
immediately), and to close the connection actively, NOT passively by user 
abort, at last, to run the function in background.


But the redirecting using function header() with location has a problem that 
header() always does return the page to user after the entire program, 
including registered showdown function finish running, which is against the 
will. I put a time consuming task into a function that registered to be a 
shutdown function and hoping it runs after the user has got the redirected 
page and the connection has been closed. But experiements (using browsers, 
curl command line tool as well as perl::LWP code) show that the user got the 
redirected page only after the shutdown function finished, which is against 
the description of register_shutdown_function at php website.


It seems only header() function use to redirect page has this problem (not 
executed until register_shutdown_function finished) while other functions 
like print()/echo(), exec() have not.


The code looks like:
-

-

http client who sends the request to the php program will only get the page 
back as response after function f finsihes (file aaa created). Changing the 
$count will make a lot difference.


My BIGGEST question is:
How to make user get the redirect page immediately after the header() is 
called, and not until function f() ends, while making sure that the function 
f() will finally fully (and might slowly) execute?


Thank you very much for kindly replying.

With high respect,

Liang
