Apache is a multi-process single-threaded architecture. 1 request, 1
process. Concurrent requests are handled by concurrent processes. What
is it you think you need a second thread for during a request?

attached mail follows:
As I know, apache-php works this way. When the web server gets an http
request with file name extension ".php", it will start the php interpreter
to process the php file.
Now I have a php program does something like this: when it is executing with
one parameter p1, the program code goes to contact a database, gets back
huge amount of data, writes it to file system. This will take pretty long
time to finish. In the mean time, the same php code will be invoked by
apache with another request, passing different parameter p2, indicates the
code need to run to check the availability and read partial of the data
which has already writen to the file system just now. The program location
need to be in the same URL, but with only different parameter passing to it.
for example:
http://baseURL/a.php?v=p1
http://baseURL/a.php?v=p2
I want these 2 process can be run concurrently, but through a small test, I
found out that they just sequentially execute one after the other.
http://baseURL/a.php
http://baseURL/b.php
howevery can run concurrently well, it means that apache can invoke multiple
php interpreter processes. But I do not know how to make php interpreter to
do the same thing. Or 2 php interpreter processes process one php program
sepreately without interfer with each other.
Hope I have explained myself clearly.
Thank you.

Sorry, your test is wrong then. Apache/PHP does not serialize requests
like that. If somehow the backend you are collecting data from is
serializing the requests, then you are out of luck and frontend threads
isn't going to solve that since your threads would simply be serialized
as well. You are on the wrong track here.

Could you please explain it a little bit more?
I did test this way.
The code is the same for a.php and b.php
<?php
sleep(20);
print Done. <br />";
?>
I place request from 2 browser windows.
First time, I placed with http://baseURL/a.php with both 2 browsers,
starting times have 5 second interval. Then the first "Done" shows after 20
seconds and the second "Done" shows 20 seconds after the first "Done".
Then, I placed one browser with http://baseURL/a.php and the second one with
http://baseURL/b.php, with starting time of 5 second interval. Then I got
the first browser showing "Done" after 20 seconds and 5 seconds later, the
second browser showed "Done", too.
Thus it seems that the apache can spoon out multiple php interpreters
responding to http requests, while php can not deal with concurrent process
from one program.
I do not know if it is due to the php's design limitation, or I did not
configure the php correctly to fulfill its full functionality?
Thank you

I have no idea what you did to configure it this way. I wouldn't even
know how to do that if you asked me to. As far as PHP is concerned it
has no idea which processes are handling which script files at any one
point. So whether you request a.php and b.php at the same time or a.php
twice at the same time, it makes absolutely no difference to PHP. If
you are really seeing this, then the limitation is in your browser or
somewhere else. Try making a.php output stuff so it becomes easier to
see. As in for($i=0;$i<20;$i++) { echo $i; flush(); sleep(1); }
You should see the counter start counting as soon as you hit the page.

Hi Rasmus,
You are right. It was the problem with the browser. I used Mozilla Firefox
to try, and do not know what consideration it just serialized the identical
url http requests. I then turned to use 2 IE 6.0 windows, 2 tabs within
Maxthon browser, one IE windows and one Firefox, to test. Then I got the
conclusion as you told. Thank you very much for the help.
BTW, I could not get the flush() work, neither flush() with ob_flush(). I
tried almost all methods mentioned in the followed posts under
http://us2.php.net/flush, but none of them can really pushed the buffer out.
The site is configurated with http://liang.ns2user.info/php/info.php on Red
head, kernel 2.4.29. What can I do to get it work?
Thank you again.

That should work. Have you checked your include_path to make sure a
different, unmodified version of the parent class isn't getting loaded?

BaseElement
|- SubElement1
| \- ExtendedSubElement
|- SubElement2
|- SubElement3
|- SubElement4
|- SubElement5
|- SubElement6
|- SubElement7
|- SubElement8
\- ExtendedBaseElement
ExtendedSubElement will never be able to inherit from ExtendedBaseElement.
there is no multiple inheritance in php.
So either change your 'tree':
BaseElement
\- ExtendedBaseElement
|- SubElement1
| \- ExtendedSubElement
|- SubElement2
|- SubElement3
|- SubElement4
|- SubElement5
|- SubElement6
|- SubElement7
|- SubElement8
... stick the functionality of ExtendedBaseElement into BaseElement
and get rid of the ExtendedBaseElement
... or figure out a neat way to use the 'Decorator Pattern'
(http://www.google.com/search?q=Decorator+Pattern) in order to
conditionally make extended functionality available in specific
descendant classes?
otherwise post some code (cutdown :-) for people to look at.

I can't change the tree, because the non-extended elements still need to
be able to function independantly.

That seems like it would work, but itdoesn't feel very clean. I'll look

Well, here is my actual tree with all the internals pulled out:
<?php
abstract class CForm_Element {}
class CForm_Datetime extends CForm_Element {}
class CForm_File extends CForm_Element {}
abstract class CForm_StandardElement extends CForm_Element {}
class CForm_Hidden extends CForm_StandardElement {}
class CForm_Checkbox extends CForm_StandardElement {}
class CForm_Radio extends CForm_StandardElement {}
class CForm_Select extends CForm_StandardElement {}
class CForm_Textarea extends CForm_StandardElement {}
class CForm_Text extends CForm_StandardElement {}
class CForm_Password extends CForm_Text {}
class CForm_Email extends CForm_Text {}
class CForm_Timestamp extends CForm_Text {}
abstract class CForm_Number extends CForm_Text {}
class CForm_Float extends CForm_Number {}
class CForm_Integer extends CForm_Number {}
?>
They are the elements of a Form Object, to create the form and validate
the input. The extended classes I'm working on now associate a database
table with the Form object, and will Create, Delete, and Update rows in
a database.
This is my currently anticpated Structure.
<?php
abstract CAdminForm_Element {}
CAdminForm_Boolean {}
CAdminForm_Email {}
CAdminForm_File {}
CAdminForm_Float {}
CAdminForm_Integer {}
CAdminForm_Password {}
CAdminForm_Select {}
CAdminForm_String {}
?>
When I was typing out this structure I realized that some of those have
2 possible objects they'll need to inherit from, which further
complicates things.
An example: I'll want the CAdminForm_Boolean to optionally be Yes/No
Radio buttons, or a Checkbox. Which is handled with two separate Form
Elements.
I'm *this* close to concluding that it would be better to not extend any
of the new AdminForm classes from any of the old, but rather instantiate
a Form Element class for each AdminForm Element, then use __call() to
pass methods through to the instantied, while overriding the necessary
methods in almost the normal way.
Thanks for your time,
Chris

Well, unless you have set your server up to execute PHP or CGI scripts
in .html files, which is a very bad idea, the only thing you need to
worry about is client-side scripting. You could just filter out all
<script></script> tags if client-side scripting isn't important for your
application...

That's one of the problems I have, but it seems a tough nut to crack. If I
leave in the scripts, it opens a possibility of malicious scripts being fed
to a user through the application.
On the other hand, if I take out the scripts, I will be providing a broken
version of the original page. People are not going to be happy if my "llama
to alpaca"-application has the side effect of deleting all of their scripts.
I've been thinking of limiting this problem by preventing the direct
displaying of the code (ie. only allowing "Save As.." for the link to the
user-submitted HTML). I guess a bit of JS could prevent accidental
left-clicking on the link. I've also been thinking of passing a special
header for the HTML source code file, "Content-type:
application/octet-stream" to suggest downloading rather than displaying the
contents, but IE seems to just ignore it and display the HTML anyhow.

That is the GD library, not the GD PHP extension. The latter requires
the former, but they are not equivalent. Please don't top-post.

Well.. it says it's found a string it wasn't expecting on, or around,
line 35 but I can't find it. Did you cut and past the code here or
retype it when you posted?
BTW... A nice editor for windows is Crimson Editor, and for the mac
TextWrangler works pretty good too. Both have built in FTP features that
are easy to use and some decent syntax highlighting. And both are free.
If your on *nix then I'm not gonna start that war... :P

I am writing a script that will read a file from a remote server and write
it to the local server. It works fine except when large files are
attempted. It times out and gives the error that the maximum execution time
has been reached and the file will only be partially copied to the local
server. Is there a way around something like this? Or perhaps could the
script keep time of how long it has been running will reading/writing and
then be able to continue writing to the partial file? Does anyone have any
suggestions for this problem?
Thanks,

Providing you feel it's safe / user friendly to do so, just increase
the time-out: set_time_limit()

Wouldn't something like rsync be better suited for this?
I only ask because I've run something like this before...

[ Note: Please reply to the mailing list - not to me personally ]
The suggestion I gave you doesn't involve the php.ini file at all -
try looking in the PHP manual for the function given.

Hey,
Below the code code I am using, but before you see it let me try to explain
it a bit to you.
Basically I first check to see if a certain image has a bigger width, bigger
height or they are
equal, according to that I call the correct function.
I point the script to a image file (.jpg) then the script resizes the pic to
120pix while keeping the
pic proportionate.
in the beginning if the height is more, then its resizing perfectly...but if
the width is more I want to
cut out 90pix from the middle of the pic...instead its giving me a skewed
image as you can see from
here:
http://www.instantclub.com/skew.jpg
(I have also drawn a red rectangle on the original for where it was supposed
to cut)
*****************************
** And heres the code I am using: **
*****************************
<?php
function prop_thumb_height($filename)
{
header('Content-type: image/jpeg');
list($width_orig, $height_orig) =
getimagesize($profile_pics_path.strtolower($filename));
//echo $_SERVER['DOCUMENT_ROOT'].$profile_pics_path.$filename;
$width = 90;
$scale_by = $width / $width_orig;
$height = floor($height_orig * $scale_by + 0.5);
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($profile_pics_path.strtolower($filename));
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height,
$width_orig, $height_orig);
imagejpeg($image_p,$profile_thumbs_path.$filename, 100);
return $height;
}
function prop_thumb_width($filename,$the_height)
{
$width = 90;$height = $the_height;
header('Content-type: image/jpeg');
list($width_orig, $height_orig) =
getimagesize($profile_pics_path.strtolower($filename));
if ($width && ($width_orig < $height_orig))

return $width;

function CR_make_crop($filename)

imagedestroy($img);
return $new;
}
/////// All functions on top
$pic1_name="1UilXQSj2S5VV29L.jpg";
// #### Get image size
list($the_image_width1, $the_image_height1) = getimagesize($pic1_name);
if($the_image_height1 > $the_image_width1)
{
$make_prop_thumb_and_get_height=prop_thumb_height($pic1_name);
$step1=$make_prop_thumb_and_get_height-120;
$step2=round($step1 / 2);
$im = CR_make_crop2($step2,$pic1_name);
imagejpeg($im,strtolower($pic1_name),80);
imagedestroy($im);
header('Content-type: text/html');
}
elseif($the_image_height1 < $the_image_width1)
{
prop_thumb_width($pic1_name,$the_image_height1);
$im = CR_make_crop($pic1_name);
imagejpeg($im,strtolower($pic1_name),80);
imagedestroy($im);
header('Content-type: text/html');
}
else // Width and height are same
{
$im = CR_make_crop($pic1_name);
imagejpeg($im,strtolower($pic1_name),80);
imagedestroy($im);
header('Content-type: text/html');
}
?>
Any ideas? I know I screwed up somewhere in the function...but just cant
figure it out...
Thanks,
Ryan

If the width is greater than the height you're calling CR_make_crop
which has this line:
imagecopyresized ($new, $img, 0, 0, 0, 0, 90,120,$width_orig2,$height_orig2);
The problem is that what you're effectively saying is:
Copy the entire original picture (0,0 to $width_orig2, $height_orig2)
into an area 90x120, and resize it when you do it.
That's not a crop :) That's a resize. You'd be better off with a
function like imagecopy() instead - once you have that 90x120 cropped
piece, then you can do whatever it is you wanted to do with it.
Best regards,
Richard Davey

I am working on a script which will open a remote PHP file (located on one
of my other website servers) and collect information that gets outputted
from the remote file. I have it working now by using the fopen() function
to open the file on the remote webserver. I am just wondering if it is
possible to collect information and log the info with code in the remote
file. I basically want to keep a log of all domains/servers/ip addresses
that are accessing this remote file and store it in a database on the remote
files server. Is it possible that when the "guest" script uses the fopen()
function to access the PHP file, that when the remote PHP file gets executed
it can log some information about the source server which is accessing it?
If so, what kind of code would I need to place in the remote PHP file to
obtain some of the information.
Thanks,
Matt Palermo
