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.

Re: [PHP] Try to find a solution, when restart Apache with PHP Script
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...

[PHP] Re: PHP preg_replace help
Just use stripslashes() on your submitted data and forget about testing for magic_quotes. It's good practice anyhow. \ is not legit text regardless. haim Chaikin wrote: 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.

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.

You have to manage a variable across page requests to keep track of
where you are. Use that variable in your SQL as part of your
offset/limit parameters.

Re: [PHP] Case insensitive ksort
I don't have time to look up in the manual but I don't remember a case insensitive ksort(). I think there's a uksort() where you could specify your own sorting parameters for the keys. Also, you could create the array with keys run through strtoupper() or strtolower(). If you need the proper upper/lowercase version too, you could store that separately within the array. Just some thoughts on how you could do this. good luck! -TG - Original Message - From: Christoph Boget [EMAIL PROTECTED] To: php-general@lists.php.net Date: Tue, 18 Sep 2007 11:37:01 -0400 Subject: [PHP] Case insensitive ksort I looked in the docs but didn't see anything regarding case insensitivity and I fear the functionality doesn't exist.

public function __set ($name, $val) {
echo Setting \$this-$name to $val...\n;
$this-{$name} = $val;
}
public function __get ($name) {
return The value of $name is {$this-{$name}}.\n;
}
}
?
My questions are as follows:
1) It seems that the getter and setter are not called on every single
call. For example, if I do the following:
$bar = new foo;
$bar-x = 'x';
There is no output. I would expect to see Setting $this-x to x.
Another example:
$bar = new foo;
$bar-y = 'y';
echo $bar-y;
I would expect this to see The value of y is y. but instead I just
get 'y' as output. So when do the various setters/getters get used?
2) It seems that getters ignore the visibility of properties. Why is
this? For example:
$bar = new foo;
echo $bar-z;
I would expect this to throw an error about accessing a private
member, but it outputs The value of z is z. just fine. If I remove
the __get() overloader, an error is thrown.
I'm guessing that the answer to all of my questions is some how
wrapped up in visibility and overloading. Unfortunately I cannot find
any resource that documents the interactions. TIA.

I've been doing a bunch of reading about objects and overloading in

remove public $x and it works. __set() is only called for
non-existent variables.

again, because your code sets $y with $this-{$name} = $value, the
variable $y now exists, and so __get() is not called.
If you're using normal variables, then you don't need setters/getters.
Instead, if you store the values inside an internal array (for
instance), then a setter/getter can help to abstract the array contents.
For instance, this class:
http://svn.pear.php.net/wsvn/PEARSVN/Pyrus/trunk/src/PackageFile/v2/Developer.php?op=filerev=0sc=0
(which is under development currently for the next incarnation of the
PEAR installer) allows logical manipulation of maintainers of a package
within package.xml. Instead of either direct array manipulation or the
old way, which was a complex method call that is easy to mis-order:
$pf-addMaintainer('cellog', 'Greg Beaver', '[EMAIL PROTECTED]', 'yes');
One can do:
$pf-maintainer['cellog']
-name('Greg Beaver')
-email('[EMAIL PROTECTED]')
-active('yes');
and then values can be retrieved using normal stuff like:
echo $pf-maintainer['cellog']-email;
The entire time, the class is abstracting stuff that would be really
complex as it is actually accessing the underlying XML of the
package.xml directly when making the modifications.
The examples you give don't need this kind of complexity.
2) It seems that getters ignore the visibility of properties. Why is
this? For example:
$bar = new foo;
echo $bar-z;
I would expect this to throw an error about accessing a private
member, but it outputs The value of z is z. just fine. If I remove
the __get() overloader, an error is thrown.
private properties simply don't exist outside the class, so you can
create public properties on external access with impunity.
You should open a documentation bug for this at bugs.php.net

If a property is declared public, it does not need the __get and __set, so they aren't used. Likewise, $bar-y is public since it was added dynamically outside the class.

[PHP] date weirdness
I have extracted a small portion of a calendar application I developed
recently to show some strange behavior with the date() function. When I
run this I get duplicate dates occasionally down the list. I'm seeing
11/4 twice for example. Sometimes dates are missing from the list. The
results change from day to day.
#!/usr/bin/env php
?php
error_reporting( E_ALL );
define( 'SECONDS_IN_A_DAY', 60 * 60 * 24 );
define( 'LAST_SUNDAY', strtotime( 'last Sunday' ) );
echo 'SECONDS_IN_A_DAY = ' . SECONDS_IN_A_DAY . \n;
echo 'LAST_SUNDAY = ' . LAST_SUNDAY . \n;
for( $x = 0; $x 365; $x++ )
{
$seconds = LAST_SUNDAY + ( SECONDS_IN_A_DAY * $x );
$date = date( 'n/j', $seconds );
echo $seconds $date\n;
}
I get the same results with latest PHP4 and PHP5.

Re: [PHP] Try to find a solution, when restart Apache with PHP Script
On 9/17/07, Rodolfo De Nadai [EMAIL PROTECTED] wrote: 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. Hi Rodolfo- I think you are going about this the wrong way. You shoud not have the PHP script itself execute the forever running task, it should just trigger the separate starting/stopping of the task. There are several ways to do this, the first two that spring to mind are: 1. Create a custom init-script in /etc/init.d (or wherever your distribution has init scripts) that the PHP process triggers with a start command (/etc/init.d/myprog start). This will require root privileges for the PHP process (or no-password sudo privileges for that command). --or-- 2. Have a cron job running as a user that has appropriate permissions. This cron job should look for the presence of specific files - if it sees them, it takes the appropriate action, and then deletes the trigger file. For example, have the cron job watch for the presence of /tmp/startMyProg.marker - when it sees it, it starts the program and deletes /tmp/startMyProg.marker. Also have it watch for the presence of /tmp/stopMyProg.marker, when it sees that, it would stop the running program, and delete the marker file. At this point, all your PHP script has to do is create the appropriate file in /tmp (could be as simple as a exec(touch /tmp/startMyProg.marker) call). Hope that sends you a workable direction- James -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Using seconds is a hack that doesn't account for DST. Use the following
instead:

define( 'LAST_SUNDAY', strtotime( 'last Sunday' ) );
echo 'LAST_SUNDAY = ' . LAST_SUNDAY . \n;
