I've been creating a number of CM applications for a virtual-host website. One feature, of several applications, allows the editor [one of our people] to create simple text files. I've been using simple flat-files in a directory for saving the files. I've gotten tried of dealing with directory permission problems, etc., and am considering using a simple mySQL DB for storing the file strings. Obviously, for each file-string to be unique, its path must be included as part of the ID. Here is my question. I can use one table for all the path/files and use the following as the primary key /home/some-dir/filename. fields: fullpath-filename | path | type | date | binary-string path is so the code can do an equivalent of scandir() type signifies whether data has been serialized() or not. This is so I can save arrays date is the equivalent of file last mod date. Or, I can create a separate table for each full-path used and then just use the filename for the primary key. In this case, since the table name is in effect the path, only the filename is needed. The first approach is obviously simplest; but, I'm concerned about getting myself into a trap later on. Anyone offer any suggestions?

Hi guys. I'm having some trouble here regarding a project. I have a table with projects, wich can be recursive (ie. sub-projects) and it is related to itself. By making the following query -8-- SELECT * FROM projects LEFT JOIN projects proj_parent ON projects.project_parent = proj_parent.parent_id WHERE project_id = 1234 -8-- i need to be able to access to the parent project's fields, but I have a slight problem here. First off, I have to make the LEFT JOIN. I don't know if the project can be parent (therefore not finding a project_id = 0 wouldn't show the row) and I need to add some kind of prefix to the proj_parent's fields so that I can access them (or that they can't overwrite the project i'm getting info on. Well... there is an obvious sollution here: use an associative array instead of an object, and access the properties by doing $array[0], $array[1], etc. By my experience, this is a nightmare, maintenence-wise, so I'd only use it as a _LAST_ resource. Does anyone have any experience with this? The answer should be pretty obvious, but I can't seem to figure it out :( Thanks in advance.

Using reference variables avoids unnecessary extra copying of objects, and while using large arrays it can make a big difference in speed. You shouldn't need to worry about this -- PHP tries to take care of it for you. When you copy an array value, PHP only does a shallow copy (of the array's address); if you later modify the array, this triggers a full deep copy of all the array's element values before the modification is done.

[PHP] Re: performance.
* Rodolfo Gonzalez Gonzalez [EMAIL PROTECTED]: this could be a silly question. Is there some performance penalty when using the operator like this: $var =EOP add a bunch of text here and here EOP; Just curious. Try doing some benchmarks using microtime(). My gut reaction is that there shouldn't be any difference; heredoc syntax is simply another form of quoting strings. The other factor to consider is if a few microseconds more of processing time is worth the extra programming time it takes to get quotes right (assuming heredoc syntax *does* take longer). I personally prefer heredocs when using long, multiline strings to using double quotes -- they're easier to maintain. -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] MySQL + PHP question
Yeah I understand what he wants, but the problem boils down to the project with no parent. The only thing I can suggest is if you have a dummy row in, so the top parent row, (1) or (6) in my example with have the dummy as its parent. Then using: select b.id parentID, b.name parentName, a.id childID, b.name childName from tbl_project a, tbl_project b where b.id = a.parent and a.id = 1 Should give a row of: ParentID: 0 ParentName: Dummy ChildID: 1 ChildName: Project One So, if a Project has a parent that the name is called Dummy, then you know it doesn't have a parent.

[PHP] cURL - is it best for me?
Hi, My main site allows authenticated users to insert bibliographic data into our database. We ask them to start by putting in an ISBN or ISSN. Some documentes don't have them, or the use is too lazy to look for them. Rather than them entering jibberish, we first check that if they have entered something - that its mathematically correct (there's a algorithm to check these). Where they don't know the ISBN/ISSN, I would like them to enter their document title and then get my system to check the UK's main library biblio service (COPAC) and see if the title exists on their db. I've set up a simple cURL test which queries the COPAC site and displays the page as if it was from my site (not quite what I wanted - I'd rather have a list of ISBN/ISSNs and their associated titles without all the baggage). So my questions are: Is there a way for me to (using cURL) ask COPAC how many records match the search and if 0, return the data in a way that I can use it as I wish? If not, is there another tool that I should be using?

[PHP] Setting clock backwards hangs webserver (PHP+THTTPD)
Hi all, Iam running PHP on THTTPD 2.21b I have a simple php script that sets the system clock (using exec(date -s MMDDhhmm.ss) and returns a page showing the system time when i use it to set the time forwards, it works fine but if i use it and set the time backwards (even a few seconds), the webserver hangs. also it hangs only for exactly the amount of time needed for the backwards-set time to catch up with the original time. when the clock catches up with the original time, the page is returned. till then it hangs it's almost as if the webserver is waiting for the time to come back to the request-received time before sending the page. i dont know if this is a php problem or a thttpd problem. any pointers, please ?

Re: [PHP] On register_shutdown_function: What might be the problem?
Hi Rasmus,
This may be a little bit long, sorry for taking your time.
It still does not work as expected. I tried some experiment, and found that
if I called some function or write some code line other then calling
header(), the register_shutdown_function and other part of codes work as
expected . For example:
?php
set_time_limit(5);
function f(){
set_time_limit(10);
//doing something time consuming
}
some_function();
?
The time limit of 5 will be the limit of the some_function() and the 10 will
be the limit of function f() respectively.
Code example:
---
?php
set_time_limit(1);
ignore_user_abort(true);
function say_goodbye() {
$st = connection_status();
print Status 1: .$st.\n;
set_time_limit(10);
$st = connection_status();
print Status 2: .$st.\n;
$count=2000;
for($i=0; $i$count; $i++){}
print End!\n;
exec(touch /home/.nappy/liang/liang.ns2user.info/php/bbb);
}
register_shutdown_function(say_goodbye);
print Sleeping...\n;
$count=1000;
for($i=0; $i$count; $i++){}
print Done!\n;
?
-bash-2.05b$ curl -N liang.ns2user.info/php/v.php
Sleeping...
br /
bFatal error/b: Maximum execution time of 1 second exceeded in
b/home/.nappy/liang/liang.ns2user.info/php/v.php/b on line b30/bbr
/
Status 1: 2
Status 2: 2
End!
~~~
if I change the time limit from 10 to 5 in function f()
-bash-2.05b$ curl -N liang.ns2user.info/php/v.php
Sleeping...
br /
bFatal error/b: Maximum execution time of 1 second exceeded in
b/home/.nappy/liang/liang.ns2user.info/php/v.php/b on line b30/bbr
/
Status 1: 2
Status 2: 2
br /
bFatal error/b: Maximum execution time of 5 seconds exceeded in
b/home/.nappy/liang/liang.ns2user.info/php/v.php/b on line b14/bbr
/
~~
Change both the time limit to 10 will result:
-bash-2.05b$ curl -N liang.ns2user.info/php/v.php
Sleeping...
Done!
Status 1: 0
Status 2: 0
End!
~~
But if the some_function is header() then the rule above does not work. It
seems the function f()'s time limit also rule the header(). Only after the
registered shutdown function finishes runing normally or by hit the expire
time limit, will the header() return page to browser/http user agent.
Example code with suggestion from Rasmus as:
--
?php
set_time_limit(5);
function f(){
set_time_limit(100);
$count=5;
for($i=0; $i$count; $i++){
//sit here and loop for a bit so we can have time to hit Stop...
echo a \n; flush();
}
echo end;
exec(touch /tmp/aaa);
}
register_shutdown_function('f');
ignore_user_abort(true);
header(Content-type: text/plain);
header(Location: y.html);
echo foo\n; flush();
for($i=0;$i10;$i++) { echo $i; sleep(1); }
$fp = fopen(/tmp/foo.txt,a);
fputs($fp,$i);
fclose($fp);
?
--
After the file /tmp/foo.txt has been created, before the file /tmp/aaa being
created, the y.html will not get to the browser or perl program using
LWP::UserAgent. I think it is no way to close the connection actively by the
php program to deliver the page sooner to end the http request, even I add
lines and make code like this does not work:
header(Content-type: text/plain);
header(Cache-Control: no-store, no-cache);
header(Location: y.html);
header(Connection: close);
My project act as a broker for user agent to a library database server
called z39.50. Upon the request from user agent, my program need to connect
a z39.50 server, getting data back 1 by 1, transforming to sepcial xml
format and sending back to the request party. When the data repository is
huge (sometimes up to million records), I have to get partial data transform
and send back to user agent (normally a piece of perl code, called
harvester) with a resumption token. The harvester will in a while loop send
out another http request with the last resumption token and fetch data of
next part, until finish all data fetching. The time to connect the database
and do the query is a constant overhead. So it is not a good design that
program need to connect the database and query upon each request with or
with out resumption token. So my design is to connect to database and query
only when the first initial request comes, and reponse back with partical
data using header() and continue getting back data from z39
[PHP] Apache 2.0.52 + PHP 4.3.9 configuration problem, for Linux Fedora 3.
Hi,
I have Apache 2.0.52 with PHP 4.3.9, running on a Linux Fedora 3, and cannot
write through PHP on any folder, except for /tmp.
No matter which permissions, owner or group are set for the folders or files,
they never become writable.
When I execute the following script, I have always obtain as a result, that The
file is not writable, although it should be, because test.txt has Apache as its
owner and group, and permissions for reading, writing and executing for the
owner, group and others.
In Apache, the user and group are set to Apache, and in PHP the safe mode is
off.

[PHP] Using PHP to get user input via checkbox through a database
Hello everyone,
What I want to do is have a form (which is already created) where the user
selects (via checkbox) on an item or group of items (almost like a shopping
cart). These items are stored in a MySql database and the program was written
in PHP. So far I have created an insert form that inserts the products into a
database. The database is displayed in a form where the user now needs to
click on the select box so that he/she can choose their items. Once they have
chosen the items a confirmation page is supposed to come out with the user's
choices and the user will confirm that this is correct or not and either click
submit or go back to choose again. If they click submit than I am supposed to
receive an email with all of the user's choices. The part I am still stuck in
is when the user attempts to choose, nothing really happens. Following is the
code that displays the database and allows the user to choose via the check
boxAny help would be appreciated.

To expand a little: Zend Client is super for debugging on a localhost but if you want a team of developers to have debug / profile tools then Zend Studio Server is the tool. I would suggest that you apply for the Zend Small Business program if these tools meet your needs for one low yearly price you get both plus the encoder and the server module to handle deployments, or testing...

[PHP] Object Inheritance, get_class() and a static function call
Hello,
following code won't work in the expected way:
class ClassA {
function getClassName() {
return get_class($this); # [1]
}
}
class ClassB extends ClassA { }
echo ClassB::getClassName();
this script echoes Object instead of ClassB. but i would like to
return the classname of the derived class without writing the method again.
this will work:
B = new ClassB();
echo ClassB-getClassName();
i tried to use line [2] instead of [1]
return get_class(self); # [2]
but this only returns an empty string.
is there any solution for my problem?
i'm using PHP Version 5.0.3 (with Apache 1, Windows XP)

ah simplexml, in that case is_array() shouldn't and won't
work because it's 'all' objects (although I can understand why it seems
like it should work!) - but the objects allow array(-like) iteration
of contained elements.
read this again very carefully:
http://be2.php.net/simplexml
note also that even values are actually objects that implement
the __toString() interface (although I'm not sure that is the
correct way to explain/name it) where by the object is automatically
cast to a string in a sensible way when used with echo/print ...
as the exmaples on the simplexml page show you have to cast manually
if you want to do other things with the string representation (like
using the actually value of the object as the test value of a switch
block.
here is some more reading material:
http://www.onlamp.com/pub/a/php/2004/01/15/simplexml.html

RE: [PHP] Using PHP to get user input via checkbox through a data base
Hello everyone,
What I want to do is have a form (which is already created)
where the user selects (via checkbox) on an item or group of
items (almost like a shopping cart). These items are stored
in a MySql database and the program was written in PHP. So
far I have created an insert form that inserts the products
into a database. The database is displayed in a form where
the user now needs to click on the select box so that he/she
can choose their items. Once they have chosen the items a
confirmation page is supposed to come out with the user's
choices and the user will confirm that this is correct or not
and either click submit or go back to choose again. If they
click submit than I am supposed to receive an email with all
of the user's choices. The part I am still stuck in is when
the user attempts to choose, nothing really happens.
Following is the code that displays the database and allows
the user to choose via the check boxAny help would be
appreciated.
?php require_once('Connections/connBlog.php'); ?
?php
mysql_select_db($database_connBlog, $connBlog);

Problems I see right off the bat are:
1) your form tag has no action (action=), therefore no action will be
taken upon submit.
2) your checkboxes have no unique value, so even if your form WAS being
submitted to some other page, you wouldn't be able to tell which ones were
checked.
To solve these problems, set your form action to the page that is to process
the POST, then change this line:
input name=select type=checkbox id=select
value=checkbox
...to be something like
input name=select type=checkbox id=select
value=?php echo $row_Recordset1['product'];?

Sure! It's the first one: i'm calling a method of the class without

Re: [PHP] On register_shutdown_function: What might be the problem?
I really didn't follow all that. But this stuff is not that complex.
header() sets a header to be sent when output goes out. header() does
not send an actual header at that point. If you don't send any output,
then the headers won't go out until the script terminates. If you have
any sort of output buffering enabled, then even if you think you are
sending something, you may only be buffering it, and in that case again
the headers won't go out until the request is done.
Also, ignore_user_abort() controls whether or not your script will be
terminated when we are able to detect that the user has aborted. A user
abort is defined as nobody being around to read the data we are sending
out. If you don't send anything, we can't detect if the browser has
gone away. Generally browsers will redirect as soon as they see a
Location: redirect header, but that could be client-speficic. If the
client sticks around after seeing the redirect and doesn't redirect
until after the server has closed the connection, then there is no way
to force a close. If it does redirect and close its end of the
connection, then if you set ignore_user_abort(false) your script will be
terminated as soon as it tries to send something further and your
shutdown function will be called at that point.

Hi Rasmus,
This may be a little bit long, sorry for taking your time.
It still does not work as expected. I tried some experiment, and found
that if I called some function or write some code line other then
calling header(), the register_shutdown_function and other part of codes
work as expected . For example:
?php
set_time_limit(5);
function f(){
set_time_limit(10);
//doing something time consuming
}
some_function();
?
The time limit of 5 will be the limit of the some_function() and the 10
will be the limit of function f() respectively.
Code example:
---
?php
set_time_limit(1);
ignore_user_abort(true);
function say_goodbye() {
$st = connection_status();
print Status 1: .$st.\n;
set_time_limit(10);
$st = connection_status();
print Status 2: .$st.\n;
$count=2000;
for($i=0; $i$count; $i++){}
print End!\n;
exec(touch /home/.nappy/liang/liang.ns2user.info/php/bbb);
}
register_shutdown_function(say_goodbye);
print Sleeping...\n;
$count=1000;
for($i=0; $i$count; $i++){}
print Done!\n;
?
-bash-2.05b$ curl -N liang.ns2user.info/php/v.php
Sleeping...
br /

b/home/.nappy/liang/liang.ns2user.info/php/v.php/b on line
b30/bbr /
Status 1: 2
Status 2: 2
End!
~~~
if I change the time limit from 10 to 5 in function f()
-bash-2.05b$ curl -N liang.ns2user.info/php/v.php
Sleeping...
br /
bFatal error/b: Maximum execution time of 1 second exceeded in
b/home/.nappy/liang/liang.ns2user.info/php/v.php/b on line

br /
bFatal error/b: Maximum execution time of 5 seconds exceeded in
b/home/.nappy/liang/liang.ns2user.info/php/v.php/b on line
b14/bbr /
~~
Change both the time limit to 10 will result:
-bash-2.05b$ curl -N liang.ns2user.info/php/v.php
Sleeping...
Done!
Status 1: 0
Status 2: 0
End!
~~
But if the some_function is header() then the rule above does not work.
It seems the function f()'s time limit also rule the header(). Only
after the registered shutdown function finishes runing normally or by
hit the expire time limit, will the header() return page to browser/http
user agent. Example code with suggestion from Rasmus as:
--
?php
set_time_limit(5);
function f(){
set_time_limit(100);
$count=5;
for($i=0; $i$count; $i++){
//sit here and loop for a bit so we can have time to hit Stop...
echo a \n; flush();
}
echo end;
exec(touch /tmp/aaa);
}
register_shutdown_function('f');
ignore_user_abort(true);
header(Content-type: text/plain);
header(Location: y.html);
echo foo\n; flush();
for($i=0;$i10;$i++) { echo $i; sleep(1); }
$fp = fopen(/tmp/foo.txt,a);
fputs($fp,$i);
fclose($fp);
?

After the file /tmp/foo.txt has been created, before the file /tmp/aaa
being created, the y.html will not get to the browser or perl program
using LWP::UserAgent. I think it is no way to close the connection

I tested this on 5.0.2 and 5.0.4 and both did exactly what I expected,
namely
output nothing - $this is not defined when you call ClassB::getClassName()

my fault, again, sorry. I jumbled the different outputs. I understood
that this behaviour is coherent.

which _does_ work but is fairly pointless because you

The browser did not get the redirect page until the new $i(10) has been
appended to file foo.txt.
I also tried

And does not work.
I think it might be the case of what you suggest:
If the
client sticks around after seeing the redirect and doesn't redirect
until after the server has closed the connection, then there is no way
to force a close.
So may I draw the conclusions:
1. Server in php can not actively close the connection to make the
client see the redirect page immediately after the header has been set?
2. The connection is not closed even when the main php end and the
shutdown function is running?
If above conclusions are not true, could be somewhere that might be
wrong due to the apache-php configuration or what?
If those are true, I think I have to re-design the project flow control
and it will take sometime while I have already finished the code
assuming no above problem. Also I think this might result an awkward
design for the project. (I mean jsp will be easier to achieve a
relatively more elegant design).
I use several other program langurages for many years, but new to php,
so I probably made some assumption base on my experiences of other
langurages but not true. The project I am working now to add
enhancements is written on php. I try to keep the main design of it. I
did not expect it would be difficult to achieve this:
1. write an xml page
2. let http client get this xml page in time
3. continue do something time consuming
now I have difficulty in 2 and 3. My client is normally perl
LWP::UserAgent, and sometimes browser. I wonder how to let the client
get the page in time before I can continue to finish the rest of the
work. Otherwise the client will timeout and get no result.
Please help! Thank you.

I really didn't follow all that. But this stuff is not that complex.
header() sets a header to be sent when output goes out. header() does
not send an actual header at that point. If you don't send any output,
then the headers won't go out until the script terminates. If you have
any sort of output buffering enabled, then even if you think you are
sending something, you may only be buffering it, and in that case again
the headers won't go out until the request is done.
Also, ignore_user_abort() controls whether or not your script will be
terminated when we are able to detect that the user has aborted. A user
abort is defined as nobody being around to read the data we are sending
out. If you don't send anything, we can't detect if the browser has
gone away. Generally browsers will redirect as soon as they see a
Location: redirect header, but that could be client-speficic. If the
client sticks around after seeing the redirect and doesn't redirect
until after the server has closed the connection, then there is no way
to force a close. If it does redirect and close its end of the
connection, then if you set ignore_user_abort(false) your script will be
terminated as soon as it tries to send something further and your
shutdown function will be called at that point.

It still does not work as expected. I tried some experiment, and found

calling header(), the register_shutdown_function and other part of

work as expected . For example:

The time limit of 5 will be the limit of the some_function() and the 10

Re: [PHP] becoming root user within php
Hi Tom, First of all due to the risks involved in doing something like this.. are you sure you need to do this as root ? Secondly, are you sure this script will not be accessible via an apache server ? (i.e this is not inside your document root?) Your best bet is to use sudo (man sudo, man visudo). I would suggest narrowing down the list of commands you want to run, and only allowing those commands in your sudoers line. The man pages have lots of examples.

Re: [PHP] On register_shutdown_function: What might be the problem?
I tested the link (http://lerdorf.com/red.php) using browser (firefox 1.0),
it worked as expected, the page of redirect2.html displayed within 2
seconds. I put the exact code to my testing envirionment (2 places), as this
one: http://liang.ns2user.info/php/red.php , and the page shows up in about
13 seconds using the SAME browser.
Observation 1.
Same client(web browser on same mechine), same code on different runing
environment make difference.
I use perl code (to get page from http://lerdorf.com/red.php)
--
#!/usr/bin/perl -w
use strict;
use LWP::Simple;
use LWP::UserAgent;
# get input from command line
my ($url) = @ARGV;
# set default URL if none is given
if ( !$url ){
$url = 'http://liang.ns2user.info/liang/y.php';
print STDOUT qq{Using $url as url to fetch\n};
}
# get the html page from the web, into a string
my $ua = LWP::UserAgent-new(keep_alive=1, timeout=180);
my $req = HTTP::Request-new( GET = $url );
my $res = $ua-request( $req );
if(!$res-is_success){
my $error = $res-message();
print STDOUT qq{ERRO: with pid of $$ has ended for the following error:
$error};
exit;
}
my $htmlPage = $res-content;
print $htmlPage.\n;
exit;
--
It takes about 13 seconds to get:
~~
marvin:~/liang.ns2user.info/perl ./http_req.pl http://lerdorf.com/red.php
You are now on redirect2.html
~~
Observation 2.
=
Different clients (browser and perl LWP::UserAgent) request same code on the
same mechane result differently.
Question:
Could it be because of the configuration of linux/apache/php on the server
side instead of client side make the difference?
(2 of my testing environments are red hat linux with apache 2.0 and one is
php5.04 another is 4.3.10.)?
The php configuration is: http://liang.ns2user.info/php/info.php. I have no
read permission of those httpd.conf files so do not know how apache
configured.
Any hint? Thank you.

That's a client-side issue then, because it is certainly sent. Trying
your exact script:
?php
ignore_user_abort(true);
header(Location: redirect2.html);
echo foo\n; flush();
for($i=0;$i10;$i++) { echo $i; sleep(1); }
$fp = fopen(/tmp/foo.txt,a);
fputs($fp,$i);
fclose($fp);

It's at http://lerdorf.com/red.php if you want to test it yourself.

Re: [PHP] On register_shutdown_function: What might be the problem?
I have no experience with the Apache2 filter. On the few servers I use Apache2 on I use the handler SAPI and it works fine there as far as I can tell. lerdorf.com is running Apache-1.3 with the standard PHP Apache1 SAPI. No special setup on it. I have no idea why your Perl thing is doing something different on that link. I'm not a Perl guy. At a much higher level, it is a really bad idea to trigger any sort of long-running thing from a web request. It is way too expensive to either fork, or simply tie up an Apache process after the request in order for it to sit around and perform some sort of cleanup or cache operation. You are much better off doing these sorts of things out of band through a cron job or some sort of dedicated lightweight daemon designed explicitly for the task. The Apache process is quite heavy and should be used to handle short dynamic requests. For anything else, there are better tools for the job out there. -Rasmus Liang ZHONG wrote: Sorry for bothering again, but I did not mention the other environment on which I tested, since it has an access control to outsider.

[PHP] open_basedir Question
Hi, Has anyone else had a problem with the open_basedir restriction completely ignoring what you tell it? I've added several directories to my allowed path (separated by colons) in my Apache configuration file, and then when I go to run my scripts, I'm told that /home/sites/site1/web/ and so on is not in my allowed path of /home/sites/site1. Trailing slashes don't change anything. A little weird... This is on Linux with PHP 4.3.11. Several bugs on bugs.php.net from 2002 reported similar behavior, but I don't think it's really been corrected. If this is a bug, it's a serious one from my perspective, because it means I turn off those restrictions entirely, which makes my entire server less secure.

I have uncommented the line in the php.ini file that says 'extension=php_mysql.dll'. I have path variables set for both c:\php and c:\php\ext. One very peculiar thing that I noticed when I ran phpinfo() is that it shows the extension_dir is set to c:\php5 even though in my php.ini file it is set to c:\php.
