Hey list,
I have a php cli script that listens on a UDP socket and, when data is
sent to the socket, the script inserts it into a database. I'm using
the real BSD socket functions, not fsock.
The script runs socket_create(), then socket_bind(). Then it starts a
while(TRUE) loop. Within the loop, it runs socket_recvfrom(). I have
it running 24/7 inside a screen window.
I'm curious as to the cpu/memory/etc usage of a while(true) loop. The
`top` command shows that the process is in the sbwait state (the OS is
FreeBSD). I'm contemplating adding a usleep or even a sleep inside to
loop. Would this be beneficial? I'm not too sure of how the internals
of PHP work in terms of loops and such.
Thanks.

Is your socket blocking? If so, what's the timeout?
while(true) {
//wait for socket timeout
}
is the same as:
while(true) {
//read nothing from socket and sleep
}
Without the usleep(), the loop is going to loop as fast as your CPU
will let it - meaning 100% CPU usage, all the time, at least in linux,
although I'm pretty sure BSD would behave the same.
As far as I'm aware, sockets in PHP behave almost identically to the
way that they behave in C. I had an asynchronous TCP server written
with the socket_* functions and noticed that the while(true) loop used
100% of the CPU because of the nonblocking sockets in use, but a
usleep() solved that quite easily. Using blocking sockets with
socket_select and a sane timeout relieved the high CPU usage as well.

I believe it is blocking. Here's my socket_recvfrom:
$Recv = socket_recvfrom($Socket, $Data, 512, MSG_WAITALL, $Name, $Port);
So I think the the MSG_WAITALL is causing it to block until incoming
data connection is closed (it never reaches the 512 byte mark before

[PHP] header problem
hello
I recentrly uploaded my project from localhost to a hosting and found many
errors and warnings which didnt have in local. one of the most annoying one
is header('Location xxx').
I have used header to redirect users from pages, and kinda used it alot. i
know about the whitespace causing warning, but most of the pages i'm sending
users got html and php mixed so i'm confused about how to remove whitespace
in a html/php file. the error is :
Warning: Cannot modify header information - headers already sent by
here is a simple example, user update page :
if($valid)
{
$msg='111';
$user-dbupdate();
header(Location: /admin/index.php?msg=$msg);
}
else
{
foreach($errors as $val)
echo 'p id=error'.$val.'/p';
}
and on admin index i get $msg and display it.

$msg = $_GET['msg'];

Re: [PHP] header problem
Hi Blueman. As soon as ANYTHING has been drawn to the browser, you
cannot use a header command. So you need to work through all of your
code, and ensure that all of your logic that could result in a header
call is run BEFORE you send any html code. Is going to be tricky if
mixing html and php calls.

Several:
* Javascript - not always available on your target system, or
blocked by script blocking plugins
* Meta refresh tags - should be honored by the user agent, but may
not always be.
The problem you have is not that you need to work around this 'problem'
in PHP, but you need to fix your broken code. This problem often comes
up on the list, and is usually because of extra whitespace in include
files, or errors being output to the browser which force the headers to
be sent.

Re: [PHP] header problem
Usually, when I have to redirect the user AFTER headers has been sent (like
showing an error message), I write this:
SCRIPTlocation=page_to_send.html/SCRIPT
But this will redirect the user at once. If you want the user to read the
page, you should do something in Javascript with setTimeout(func,timeout)
function.

Don't use a timer to redirect if you want the user to read a message, as
this assumes that the visitor is a good reader. This is forgetting all
of those visitors with reading difficulties (i.e. Dyslexia), those users
who have attention problems who can't focus on text for long periods
(i.e. ADHD) and any users who rely on things such as screen readers
(which are slower than reading text yourself (if you're an average
reader!) ) or a Braille browser.
In cases such as these, it's best to let the visitor move at their own
pace and not redirect until they want to.

Ash

It's possible that on your localhost you have output_buffering set on either
in php.ini or in a .htaccess, which would avoid the displayed error about
headers. If it's switched on locally and off for your host server then
you'll get the problem you reported. Check that this is off locally (use
phpinfo) so that you can be sure your code is working properly before you
upload.
Alternatively if you want to be able to do a redirect after you've already
started your output (this is sometimes done for error handling) you could
use ob_start() to start output buffering, ob_end_clean() to clear the output
buffer and start again, and ob_flush() to send the output buffer. If you
want to continue using output buffering after an ob_end_clean() you'll have
to do an ob_start() again.

[PHP] Hoping for a hand with a login script
Hey guys,This is a simple issue I'm sure, however I'm having one hell of a
time seeing my way clear of it. I appreciate any support you guys could
throw my way.
So I'm trying to set up a small website that includes a store (
www.rareintaglio.com), i have all of my HTML hammed out and now I'm working
on creating an admin login for the sites owner to input data from a back
end. I have it set up so that he goes to /adminlogin.php, enters his info
and gains access to the back end of the website using Session variables

You are constructing your query in $qury yet you are trying to read it
from $query. Because they have different spellings they are treated as
different variables.

Re: [PHP] Performance of while(true) loop
APseudoUtopia wrote:
Hey list,
I have a php cli script that listens on a UDP socket and, when data is
sent to the socket, the script inserts it into a database. I'm using
the real BSD socket functions, not fsock.
The script runs socket_create(), then socket_bind(). Then it starts a
while(TRUE) loop. Within the loop, it runs socket_recvfrom(). I have
it running 24/7 inside a screen window.
I'm curious as to the cpu/memory/etc usage of a while(true) loop. The
`top` command shows that the process is in the sbwait state (the OS is
FreeBSD). I'm contemplating adding a usleep or even a sleep inside to
loop. Would this be beneficial? I'm not too sure of how the internals
of PHP work in terms of loops and such.
Thanks.

my system today...

Until recently, I was using screen also, but I have now switched over to
a new start/stop script. I run OpenBSD 4.3 4.5 on most of my boxes.
Once configured, this shell script can start/stop/status the given process.
I have been told that this does not start a /true/ daemon. But for me
it is close enough.
change the 4 variables at the top, just under the set -e line, and you
should have it.

Re: [PHP] Hoping for a hand with a login script
several packages available to provide it. But I believe that telling someone to adopt a complete portal system like CI just to get basic authentication is gross overkill. There has to be a better way to provide this core functionality without installing a monster package that will be 95% superfluous to their needs. I mentioned CI because it got the second-most votes on a very popular Stack Overflow question asking for PHP-framework recommendations. The most-upvoted answer discussed Zend Framework, although it's hard to tell whether it was a good review of ZF, or a negative one, on balance: http://stackoverflow.com/questions/2648/what-php-framework-would-you-choose-for-a-new-application-and-why Without knowing more about the OP's requirements, it's hard to say whether CI's other functionality would be largely superfluous. You might be right, though, and I guess my point was just to recommend that the OP look at existing, mature, free, open-source solutions before possibly reinventing the wheel. I would recommend this to anyone looking to build any sort of web app. Could be that nothing out there will end up serving your purposes, but just the experience of looking at existing frameworks, seeing how they're structured, reviewing some of their code, etc., is still likely to be valuable.

Re: [PHP] Hoping for a hand with a login script
I would recommend this to anyone looking to build any sort of web app. Could be that nothing out there will end up serving your purposes, but ... and, on further investigation, it looks like CI, surprisingly enough, doesn't actually have pre-built authentication and access control (although it does do session management).

[PHP] Reading files in PHP 5.3.0
I've been beating my head against a wall all day and can't figure this
one out. The code below worked perfectly in PHP5.2.4. However, I
recently upgraded to PHP5.3.0 and this code no longer works.
The function below accepts the path to a text file containing headers
from a cUrl session (example attached). Basically this function opens
to log file, looks for certain headers and captures some information
from that line. When called on the attached file (or any log file for
that matter), the following is output:
array(2) {
[ResponseCode]=
NULL
[ErrorMessage]=
NULL
}
Which means that nothing is getting read from the file.
Now, I'm going to qualify all of this by saying I'm running OSX Snow
Leopard, so I'm fully prepared to believe that Apple fucked something
up in it, as they have done to third party packages on other occasions
in the past. Well... to be fair, they don't usually fuck up third
party packages, rather they introduce enhancements to the OS that
prevents certain packages from working correctly and could care less
that they broke it.
So did anything change in PHP5.3.0 that would preclude the code below
from working? Am I going crazy? Or did Apple f...@# something up in
this release?
Thanks,
Steve

[PHP] RE: [Formaldehyde] The Most Basic Ajax - PHP Error Debugger
Being something nobody thought before I was expecting some comment ... zero Ajax developers here? Anyway, to make things even more simple I have released the Zero Config client side file, which works with most known browsers, IE included, and it does not require a single change in existent code, libraries included.

[PHP] Creating alphanumeric id for a table
I want to create user generated id like this :
AAA0001
AAA0002
...
AAA0009
AAA0010
where the id consists of 3 alphanumeric characters and 4 numerical digits in
the beginning (for numerical digit, it can grow like this AAA10001). I try
to use php script to generate id like this, where I use the following
script.
?
function generate_id($num) {
$start_dig = 4;
$num_dig = strlen($num);
$id = $num;
if($num_dig = $start_dig) {
$num_zero = $start_dig - $num_dig;
for($i=0;$i $num_zero; $i++) {
$id = '0' . $id;
}
}
$id = 'AAA' . $id;
return $id;
}
$app_id = generate_id(1);
?
I assume that I can get increment value/sequence from db (I used harcoded
increment value in the code above (generate_id(1))),
but I don't know how I can get this incremental value from db.I use mysql
5.0.
Or has anyone had another solution to create this alphanumeric id ?
Any help would be much appreciated
Thanks

Subject: [PHP] Reading files in PHP 5.3.0
To: php-general@lists.php.net
Date: Thursday, September 10, 2009, 4:13 PM
I've been beating my head against a
wall all day and can't figure this
one out. The code below worked perfectly in
PHP5.2.4. However, I
recently upgraded to PHP5.3.0 and this code no longer
works.
The function below accepts the path to a text file
containing headers
from a cUrl session (example attached). Basically
this function opens
to log file, looks for certain headers and captures some
information
from that line. When called on the attached file (or
any log file for
that matter), the following is output:
array(2) {
[ResponseCode]=
NULL
[ErrorMessage]=
NULL
}
Which means that nothing is getting read from the file.
Now, I'm going to qualify all of this by saying I'm running
OSX Snow
Leopard, so I'm fully prepared to believe that Apple fucked
something
up in it, as they have done to third party packages on
other occasions
in the past. Well... to be fair, they don't usually
fuck up third
party packages, rather they introduce enhancements to the
OS that
prevents certain packages from working correctly and could
care less
that they broke it.
So did anything change in PHP5.3.0 that would preclude the
code below
from working? Am I going crazy? Or did Apple
f...@# something up in
this release?
Thanks,
Steve

What does var_dump($line); tell you?

Authentication is a basic function that should be used for any web site with interactive features. There is such a universal need for this function that there should be several packages available to provide it. But I believe that telling someone to adopt a complete portal system like CI just to get basic authentication is gross overkill. There has to be a better way to provide this core functionality without installing a monster package that will be 95% superfluous to their needs. Yes, I have installed codeigniter. I am still trying to figure out why I would want to use it. Moreover, I'm using CI right now, and as far as I know, it does *no* user authentication. I had to write my own routines, using their session class to save the user data. Paul -- Paul M.

Re: [PHP] Creating alphanumeric id for a table
Note that this approach has risks around race conditions. Anytime you have a construct for the id you run the risk of having it create duplicate ids. You will need to handle that.
