Re: [PHP] unexplainable - page generation time class
I think the problem is how, when and where you're calling things.
Basically, your code is fine. I modified it slightly and get the correct
output. This could still be cleaned up and optimised significantly;
however, I think you can take it from here:
Your Class:
?php
class page_gen {
//
// PRIVATE - DO NOT MODIFY
//
var $cls_start_time;
var $cls_stop_time;
var $cls_gen_time;
//
// FIGURE OUT THE TIME AT THE BEGINNING OF THE PAGE
//
function start() {
$microstart = explode(' ',microtime());
$this-cls_start_time = $microstart[0] + $microstart[1];
return $this-cls_start_time;
}
//
// FIGURE OUT THE TIME AT THE END OF THE PAGE
//
function stop() {
$microstop = explode(' ',microtime());
$this-cls_stop_time = $microstop[0] + $microstop[1];
return $this-cls_stop_time;
}
//
// CALCULATE THE DIFFERENCE BETWEEN THE BEGINNNG AND THE END AND
COLOR CODE THE RESULT
//
function gen($start, $stop) {
$this-cls_gen_time = $stop - $start;
return $this-cls_gen_time;
}
}
?
index php that calls it:
?PHP
require_once(timer.php);
$page_gen = new page_gen;
$start=$page_gen-start();
sleep(2);
$stop=$page_gen-stop();
echo(start/stop: $start $stopbrbr);
$gentime=$page_gen-gen($start, $stop);
echo generation time: . $gentime;
?
Output:
start/stop: 1110096261.12 1110096263.13
generation time: 2.00168681145
All the best,

?
What happens is it simply returns the $this-cls_start_time variable.
Both the start() and stop() functions work fine because to test them I
put print commands at the end and they both returned proper results, the
error appears to be in the line where I minus the start time from the
end time. It simply returns a negative start time instead of minusing
the two.
I tried changing the minus to a plus for testing sake and it just took
out the negative. Does anybody have any idea what is going on here?
Thanks-you

If the password is stored in between the ? and ? tags, then it shouldn't get sent to the browser unless you specifically send it there. However, there are sometimes security problems in web servers, which would mean that attackers were able to see the source of your script, and therefore the password. For example: files called .php might get processed properly, but if the attacker requests filename.PHP, it might just send him the file in plain text. Best thing is to use 'include' or 'require' to get the password from another file which doesn't sit on a part of the filesystem that's accessible over the web. Or, you could password-protect the script you're including with .htpasswd / .htaccess protection. -- AdamT Justify my text?

Re: [PHP] warning question about mysql sessions concurrency
Josh Whiting wrote: I've been trying to switch to MySQL-based session storage instead of the native PHP session storage. In doing so, I've run into a lot of code on the web that exhibits a serious flaw regarding concurrent requests from the same client. All the code I've seen has glossed over the need to lock the session for the duration of the request, e.g. not allow concurrent requests to use it until it has finished. PHP's native session handler correctly does this, but lots of MySQL-driven session code does not. Neither do. Example timeline: 1. client sends a request 2. session data is loaded from the db 3. same client sends a request before the first one is finished (e.g. frames, tabbed browsing, slow server response times, etc) 4. session data is again loaded from the db 5. the first request changes some values in $_SESSION 6. the second request changes some values in $_SESSION 7. the first request writes the data to the db and exits 8. the second request writes it's data (over that written by the first request) and exits PHP's native handler solves this problem by forcing concurrent requests to wait for each other. The same thing needs to happen in a database-driven session handler. No request should be blocking (i.e. wait for concurrent processes to execute). This implies a poor understanding of transactional processing from both yourself and PHP! SO, does anyone have some code that uses MySQL to replace PHP's native session storage that also correctly handles this concurrency problem? Ideally I'd like to see just a set of functions that can be used with sessions_set_save_handler() to transparently shift PHP's sessions to a database, but I'm not going to use the stuff I've found on the web or even in books (appendix D of O'Reilly's Web Database Applications with PHP MySQL publishes code with this problem). Forget it - rethink how your application is architected. Folks using database sessions who do not deal with this scenario be warned! I'm surprised so much bad code is going around for this task... Agree. Some guidelines, from my experience of developing time-critical transactional systems in .Net (100 transactions/second type load). - You usually only store some kind of identification for a user in the session - no other data. doing otherwise is dangerous as there are multiple copies of data floating around uncontrolled. A session-id is enough information to store. Don't use the session for storing data willy nilly - it is for identifying the session only - nothing else. Can't say that enough. Don't use it for shortcutting code. - If you want a proper transactional system, there are two ways to handle concurrency: 1. Block until the transaction is committed - no good for performance and scalability as you spend more time waiting than doing. 2. Fail commit on change. A sample solution: For each row, add an INT which is incremented every time the data is updated (or use TIMESTAMP in MySQL if you have to use it). Read the value with the data and send it every time the data is saved. If the value is the same when it is recieved, then consistency can be guaranteed so update the row, else rollback the transaction (and tell the user someone else changed it before them - reload the view and give them an opportunity to update it again). This requires a good understanding of the DBMS you are using and the principles around ACID compliant databases. I'd personally recomment PostgreSQL over MySQL as MySQL is not truly atomic and can't do transactions database-side (no server-side programming) which makes it about as scalable as a brick. Small updates/reads yeah but nothing much more complicated. Personally, no-one in the PHP/MySQL arena tends to understand these concepts as the two technologies are rarely used for pushing data around on big systems (this is generally Java/Postgres' domain). I ONLY use PHP/MySQL for knocking up quick web apps to fart out content - nothing serious because it's simply not suited.

No request should be blocking (i.e. wait for concurrent processes to execute). This implies a poor understanding of transactional processing from both yourself and PHP! On the contrary, when dealing with a session store (in PHP, which AFAIK always writes the session and the end of the request), it's very important for serial access instead of concurrent. Take the following sql from two MySQL clients: client 1: start transaction; client 2: start transaction; client 1: select * from mytable where id=1 FOR UPDATE; # i.e. give me the data from the row with a write lock client 2: select * from mytable where id=1 FOR UPDATE; ... client 2 is going to have to sit there and wait until client 1 commits or rolls back. that's how it should work with the session store. each PHP request should acquire a write lock on the session so no other request can even *read* the data until the original request is done. - You usually only store some kind of identification for a user in the session - no other data. doing otherwise is dangerous as there are multiple copies of data floating around uncontrolled.

function gen() {
$this-cls_gen_time = round($this-cls_stop_time -

then, on the page you want to time, just put at the top:

$pagegen = new page_gen();
$pagegen-start(); // START TIMING

What's up Rory... actually there *is* a difference. Double quotes are
parsed by the php engine, meaning it goes through and finds variables
and stuff which it can parse, ex. print(Here is a variable:
$variable!); will print Here is a variable: The value of the variable!
Single quotes are not parsed by the php engine, so the same code with
single quotes (print('Here is a variable: $variable!'); will return
Here is a variable: $variable! I hope that answeres your question

Re: [PHP] Newbie question: qutoes?
Double quotes expand variables, that is, if $a = 2, then echo The value is $a2; will print The value is 2. Single quotes return strings literally. So, echo 'The value is $a2' would print The value is $a2 Cheers rory walsh wrote: Can anyone tell me if there is a difference between double quotes and single quotes?

[PHP] Opening files....
Hello, I want to open files in a directory other than the Document root via HTTP on the client machine. How do i do it ? For example I have .JPG files in a directory /toallocate on my Server running FC2, Apache2, Mysql, PHP5. I allocated certain .JPG files to some users and moved them to a directory called /allocated and logged the absolute path in a Mysql Table with the user name. Now we know the username and the files allocated to him and their path. When the user logs into his account, he should see the file allocated to him and they should be clickable links so that when he clicks them they open in the required software. I tried just providing links to their absolute path but then it doesnt work because Apache looks for them relative to the Document Root. Please some one help me in this concern, I will wait for a quick reply. Also, Is there a way that I can force the .JPG files to open in a particular software ? thanks in advance Vaibhav Sibal -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Opening files....
Hello, I want to open files in a directory other than the Document root via HTTP on the client machine. How do i do it ? Yes, it's possible Just supose you have the images under /var/images/. This won't be acceded by apache since it's out of documentroot. You can set up some alias to /var/images For example alias /images/ /var/images/ The problem is, that most servers don't let users access directories outside the DocumentRoot of the customers VirtualHost. Also, if you can read that directory, you can create a path images in your documentroot, and create a .htaccess file like this: ErrorDocument 404 image.php In image.php you catch the referrer with $_SERVER['http_referrer'] and display the image sending the header img/jpeg Also, Is there a way that I can force the .JPG files to open in a particular software ?

[PHP] Undefined Variable Problems...
Sorry if this has been covered before. I just joined this list.
My host just upgraded PHP to 4.3.10 from 4.1.2. A couple of my clients are
using systems such as PHP-NUKE or various message boards. I hadn't been
paying attention to my log files, but all of a sudden they got huge,
especially the error logs. They're filled mostly with undefined variable
errors, but also a couple others, for example:
[Sun Mar 6 00:35:50 2005] [error] PHP Notice: Undefined variable:
forum_admin in /home/scott/.org/html/mainfile.php on line 79
[Sun Mar 6 00:35:51 2005] [error] PHP Notice: Undefined offset: 1 in
/home/scott/.org/html/mainfile.php on line 486
[Sun Mar 6 00:35:51 2005] [error] PHP Notice: Undefined index: 2 in
/home/scott/.org/html/mainfile.php on line 216
line 79, if ($forum_admin == 1) {
line 486, $uname = $cookie[1];
line 216, $pwd = $user[2];
Line 79 is not part of a function or class. It is the first reference to
$forum_admin in the script. The other two are within functions and the
first call within those functions. What's being assigned to both of them
are either in the function call itself or globals.
I do have globals turned on.
Should I worry about any of this? The pages seem to be working fine? Is
this going to slow things down? Should I just turn off the logging of such
errors, if I can?
Thanks for any help. My log files are in the gigabytes with 90% of that
over the last month.

you mean register_globals? Turn it off unless this breaks things in a
major way... even then you should consider recoding if that's feasible.

uninitialized variables + register_globals is usually a bad
combination... especially when we're talking about a varaible like
$forum_admin.
http://.com/forums/post.php?forum_admin=1user=whoever
In a simple case the above can happen and someone gains admin rights...
in worse cases you end up with SQL code dropping databases...
Thanks for any help. My log files are in the gigabytes with 90% of that

ignoring the E_NOTICE errors is a good idea on a production site anyway.
That being said... I would try to fix the code so that the notice
doesn't get produced in the first place.

[PHP] Re: Help with dates
well, you can simply use the unix timestamp, since the amount of days / seconds since 0 AD/BC will be a constant (it won't change, trust me), you can simply add it to that, and add a wrapper function to php's time(). You'll be working with VERY big numbers in that case, so you can also do it the other way around; store the amount of DAYS since 0 AD/BC till Jan 1st 1970, add time()/86400, and you'll have the amount of days since 0 AD/BC in an integer (or float, depending on how many days that really are). You'll just need to find that constant somewhere :) Kevin wrote: Hey mr. Barnett, Unfortunately, I do need an accurate calculation, because the calculation will run 2 ways. From and to our calendar.

R http://php.net/set_include_path
Ok... Maybe I should put all this together in one e-mail so that all
the issues can be looked at...
The problem:
Finding a reliable method to include files, keeping in mind the
following:
1. The site could be moved to a completely new host which could be of
a different OS, and/or web server software, and could either be the
one and only site on that host (dedicated server), or could be a
virtual host (shared server).
2. The site could remain on the same host but is required to move to a
new path. i.e. from htdocs/mysite to htdocs/mynewsite
3. The web host may or may not allow the use of .htaccess (Some Sambar
configurations for example).
4. The method used would not affect any other virtual hosts. Meaning,
the method used must be independent for each virtual host.
5. The method used would not utilize a folder where other virtual
hosts could gain access to the included file (php.ini
include_path).
6. The method (and this is the important one IMHO) would not require
editing x number of pages in a site to change some static path
that was set on each page.
7. The method used would not require a dedicated include file in
every single folder of the site that could be included because it's
in the same folder as the page needing it, because those would all
have to be edited to fix the path if condition 1 or 2 was met.
Previously proposed solutions:
1. PHP.ini include_path
This affects all virtual hosts and would require administrative
overhead to prevent the owners of each virtual host from gaining
access to other virtual host's include files. I suppose you could
set it to something like: include_path=/php/includes and have a
separate subfolder under that for each virtual host. But since that
folder is outside the web folder, there would have to be some
mechanism (additional FTP account) for each person to gain access
to their own include folder to add/edit/delete files in that
folder. Then if the site is moved and they aren't using an
include_path, you have to fix all your pages.
2. set_include_path
This means if your site moves, you must edit x number of pages in
the site to correct the path.
3. An include file in every directory to set the include path.
You'd have to edit x number of these files to correct the path if
the site moves. This would be much less work than the previous
item, but it could be a lot of work on very big sites where you
don't have shell accounts to do some scripted find/replace with.
4. Use the full URL to the file in the include statement.
See item 2.
5. $_SERVER[DOCUMENT_ROOT] and $_SERVER['PATH_TRANSLATED']
Not always available or incorrect see
mid:[EMAIL PROTECTED]
I may have missed some things, and if I've misunderstood how something
should work, then please let me know. I'm just looking for a more or
less foolproof method which doesn't require fixing code if the site is
moved. The closest I can come to it is the function I wrote but is a
pain because you have to put it in every page where you need an
included file. Granted, you only have to do it once, and then you're
done and a site move wont affect it, but it's still kludgy if you ask
me.
***
?php
function dynRoot()
{
$levels = substr_count($_SERVER['PHP_SELF'],/);
for ($i=0; $i $levels - 1; $i++)
{
$relativeDir .= ../;
}
return $relativeDir;
}
?
***
and then calling it as such:
include(dynRoot() . 'includes/db_connect.php');
I've had to move client sites between Sambar, Apache, IIS and Windows,
Linux. Most times I've had to go in and fix include paths because one
of the above solutions were originally used and wasn't viable on the
new host.
Thanks.

Hello Marek, Sunday, March 6, 2005, 7:08:24 PM, you wrote: I don't see where that tells me where the include folder would be. MK If you know how the files are layed out in your application, you do. No... You missed the point of this whole thread which was explained in point 1 and point 2 of the Problem section. Restated in different words is how do you write some code which is dynamic enough to withstand reorganization of folders either on the same host, a different host (maybe with a different OS too), or a mixture of any. In HTML, a css declaration as follows: link rel=stylesheet type=text/css title=Site CSS href=includes/site.css / works regardless of where the page is, where it's moved to, and regardless of how many folders down it is as long as there is indeed a folder off the site root called includes and as long as there is a file in that folder called site.css. How do we mimic that capability in PHP so pages don't have to be re-written if point 1 or point 2 of the Problem are met?

Sorry for that all my friends, I just came from a vocation during the weekend, so I can't read your threads. Thanks for all your help. The debug_backtrace() is powerful to debug, but when I construct my classes with simpleTest or other opensource applications, it contains lots of info that I don't concern on in my application. So I decide to write or find something a little bit simpler. I just want to trace my application with the debughelper, when I want to see what happened in it.

this is the part that's causing the problem. u can leave it empty and
let the system put the admin's email id. don't leave it incomplete
though.
i agree that there are logical errors regarding the data he's used,
but that's not why it didn't work.
@Robert: u may want to print/echo all the vars for mail() before using
it, helps to debug. check all $POST vars too. this is how i generally
set the headers:
$headers = From: $fname $from_email\n.Return-Path: $ret.\n;
i use return path so that bounce messages/delivery failures go to another id.
if u want to add the X-Mailer header:
$headers.= 'X-Mailer: PHP/' . phpversion().\n;
(note ^^^ the dot)
if still doesn't work, replace ur \r\n with \n. check manual page for details.
considering that u're possibly mass mailing...
http://us2.php.net/manual/en/function.mail.php
[quote]
Note: It is worth noting that the mail() function is not suitable
for larger volumes of email in a loop. This function opens and closes
an SMTP socket for each email, which is not very efficient.
For the sending of large amounts of email, see the PEAR::Mail, and
PEAR::Mail_Queue packages.

u could also open a pipe to the mail program...

[PHP] mac os x - not getting headers already sent error
I do all my development on mac os x. sometimes, to debut a script, i output the query to the page. quite often the page sends headers to go to another page. When i do this, i comment out the header() function and read the results. When i'm done i remove the comment Sometimes I've forgotten to take out the debugging output. Now, on my server here, the page redirects and loads fine. But in the live environment, it craps out and people are left staring at a blank page. The test server is the same computer i'm developing on. Anyone know why this happens, and how i can fix it?

The other two folders moving back up the tree are the same result.
So the final looks like:

Both our solutions suffer the same problem. They have to be on every
page that requires an include, because we can't rely on a new host
having our code in their auto_prepend file

function dynRoot()

$levels = substr_count($_SERVER['PHP_SELF'],/);
for ($i=0; $i $levels - 1; $i++)

LG solid, but only because I haven't broken it yet. :-)
LG Both our solutions suffer the same problem. They have to be on every
LG page that requires an include, because we can't rely on a new host
LG having our code in their auto_prepend file
LG **
LG function dynRoot()
LG {
LG $levels = substr_count($_SERVER['PHP_SELF'],/);
LG for ($i=0; $i $levels - 1; $i++)
LG {
LG $relativeDir .= ../;
LG }
LG return $relativeDir;
LG }
LG include(dynRoot() . 'includes/somefile.php')

LG Thanks again!
LG Cheers,
LG Leif Gregory

I do this for security as I have things in include that I don't want
to be avaiable directly to the browser Also you don't need a path for include
files you can just do:
include('somefile.php');
and it will be found regardless of where the script is located.

Re: [PHP] mac os x - not getting headers already sent error
Jonathan Haddad wrote: I do all my development on mac os x. sometimes, to debut a script, i output the query to the page. quite often the page sends headers to go to another page. When i do this, i comment out the header() function and read the results. When i'm done i remove the comment Sometimes I've forgotten to take out the debugging output. Now, on my server here, the page redirects and loads fine. But in the live environment, it craps out and people are left staring at a blank page. This means that on the live server, error_reporting is at such a level that the Warning that is generated by php -- the Cannot modify header information output started at line isn't displayed, and since there is output to the client, the header() call fails, which is why you are left with a white screen. You can use output buffering to avoid such a problem; there is also the header_sent() function.
