Hi! I have some text and JPEG files inside a directory like:
1992-7-11.txt
1992-7-11_pic1.jpg
2000-4-10.txt
2000-4-10_pic1.jpg
2004-5-2.txt
2004-5-2_pic1.jpg
On a Windows box (XP + Apache), if I do a dir_object->read() for the
directory, read() reads the files above "in order" (eg.
1992-7-11.txt...2000-4-10.txt...2004-5-2.txt) even the time stamps on these
files are different.
However, after I ftp them to a Linux box and load the php script from the
Linux box, the order is gone. The time stamps on those files on the Linux
box are the same since they were all ftp and cp at the same time.
Does anyone know why? Can anyone suggest a simple solution?
Thanks.

Use glob() instead and then use sort() on the returned array.
That should put things back in order
<?php
$ar = glob('/dir/');
sort($ar);
# This should display the files in order
foreach ( $ar AS $file ) {
echo $file;
}
?>
Hope that helps

forgot, you might need to use the extension, like so.
glob('/path/to/files/*.txt');
glob() does recognize '*' & '?' as multi & single char replacements.

but, to explain why it happens, it going to be like describing the
differences between *nix and windows.
Simply put, internally, they store file information differently and by
doing this differently, they display the file list differently.
Also, *nix file names are case sensitive and windows is not. Be careful
with this one, it will bite you at some point.

Daevid, understood... but in my case the php script is called once one
time, and then keep's on running "forever" on a server background shell...
The user never will have to worry about the process again, but if the
process is not running on the server a message will apear on the
interface or a email will be send to the administrator (me and others)...
The best solution for me will be the possibility of running this PHP
script on other port than the default using by apache.
Thanks

We put a timeout at the top and show an error if the server never comes
back. You could do whatever you want. As long as the user doesn't try to
refresh the page or go somewhere else on your server, the ajax will just
keep trying in the background. That's all client-side JS / AJAX.

Subject: [PHP] Try to find a solution, when restart Apache
with PHP Script
Hi all...
I'm facing a serious problem with my application. I have a
script write
in PHP that starts in Internet Explorer, this script keep
on running
until a varible value change on my MySQL database.
The problem is that when i restart Apache, the process child
initalized
isn't kill... then the apache can't be start because the
script is use
the port 80.
To solve my problem, without change anything, the best
would be that
when i execute the script, it run on other port than the
default 80...
so this way apache could start...
The is a way to redirect through php, so the script run on
a diferent
port?? Like change some line, or add on php.ini files?? or even in
programming??
thanks ... for any info
We do something like this, wherein sometimes we have to
force a restart of
Apache, so in order to not kill the web page for the GUI,
we use AJAX to
continually poll the server. Then when the server is back,
we can issue a
page refresh to whatever page we want...

Just use stripslashes() on your submitted data and forget about testing for
magic_quotes. It's good practice anyhow. \" is not legit text regardless.

Hello,
I am a beginner in PHP. I need help with the function preg_replace.
I am trying to remove the backslashes ( \ ) from a string that is submitted
by the user.
It is submitted in a form but it adds \ before the quotation marks ( " ).
Will this change if I use the GET method instead of POST.
If not can you please tell me how to use preg_replace to remove the
backslashes.
Thank You,

From your above examples, two questions come to mind:
1.) Is thumb.php in a folder above `data`? If not, adjust
your path accordingly.
2.) When using the query ?filename.jpg are you going to call
that as an $argv[1] variable? If you want to use it as a $_GET,
$_POST, or $_REQUEST, it will need a variable name with an assigned
value. For example:
<img src="thumb.php?img=filename.jpg">
L>thumb.php
<?
$path = "../data/original/"; // In case it's a same-level
directory as the PWD
$img = $_GET['img'];
header("Content-type: image/jpg");
readfile($path.$img);
?>

thank you Mr. Brown for your reply,
yep thumb.php and img.php are in the same level
correction for img.php
<img src="thumb.php?url=filename.jpg" />
i don't know what wrong with it, when i save the image data to another
files, the image didn;t corrupted, but when displayed dynamically it's
corrupted.., and the path are ok ;)
did i miss something on this, and i didn;t aware of it ?

The general rule is to create or maintain every page on your server of what you
what the client to see. Then send it for every submit. That way you don't have
to worry about satisfying every browser and configuration there is.

I'a writing first time so sorry if i reapeat but
i wanted to say this in my own words and angle.
My question is :
Lets assume that we'r going throught php/html files
a-----> b ------> c
|<--------|
1)From a to b through a link
2)from b to c through a submit button (post method)
3) c is a php script which does some mysql queries and changes
some session variables and outputs a location header to
return to b.
While back in b we press the back button
when back button is pressed
my icewiesel browser gets me to 'a' page.
Trying to find some sense i postulated
that a browser holds in its history (for back/forward)
only requests made explicitly by the user and not the ones
made from withing php files (with header commands) .
Is my theory right..
I'm searching in the broader context of trying to control
how my bookstore website will react to random events from
the user (back/forward, links etc) while in a middle of
a series of php files that i want to act as a transaction.
Any help- recommendations for study on the subject would be very
welcomed. I have 3 books on mysql/php but that issues
r not examined,
