Actually the way most garbage cleanup routines work, the session datastore
will be removed regardless of whether it is "in use" or not.
Here comes the tricky stuff, if php has sent a page to the browser and has
satisfied your browsers request, and your user is reviewing the contents of
the page to decide his next action, as far as apache and php are concerned,
that users session is no longer "in use". But, if in the process of
preparing that page, it was using sessions, it would have stamped the
session datastore with a new timestamp, so the garbage cleanup routine would
not consider it an old datastore and remove it. If the user waits a long
time (longer than gc_maxlifetime in seconds) before doing something, when
someone else requests a page, their session could trigger a cleanup process
and your session could be deleted.
If your script is running, fetches the session datastore, and has not
reached the end of it's processing where it rewrites the datastore with
updated data and a new timestamp, if during that time the file is deleted,
no harm done since the save session routine of your script will make sure
the datastore is created and write stuff back into if from it's memory
image. I guess that is what PHP would consider "in use", whereas your user
will consider the time he is mulling over his response as "in use", even if
he gets up to get a cup of coffee before responding.

The gc_maxlifetime setting controls how "old" files can be before the garbage
collection process deletes them, when it's actually started. This is why your
file system must support atime as mentioned before. If the file has not been
accessed in over 1440 seconds (by default) then if the garbage collection
process is started, it'll be deleted.
Like I said in my other post, though, there's only a 1% chance of the garbage
collection process being started (by default). These old files you see are
probably there because you don't have enough traffic to trigger garbage
collection or your using a file system that doesn't support atime.

create_function -- Create an anonymous (lambda-style) function
The keyword here is anonymous, as in 'not named'. The anonymous
function you create will have a name but it's not a name you can use,
it's just a randomly generated string for preventing naming
collisions. That's why you must access anonymous functions with a
variable.

Hello,
For table form format ( sample ),
<form method="" action="">
<table>
<tr><td>Your Name : </td><td><input name="name" size=30
maxlength="60"></td></tr>
<tr><td>Address：</td><td><input name="address" size=30
maxlength="60"></td></tr>
</table>
</form>
"name" and "address" is varible, so how can we pass these two varible without
register_globals function ( actually it is disable ) to another webpage ?
Many thank for your help !
Edward.

Your method and action are blank.
<form method="post" action="whatever_page.php">
You need a submit button.
<input type="submit" name="add" value="Submit">
Submit will pass the vars to whichever page action is set to. The vars
will be in the $_POST array, basically $_POST['name'] and
$_POST['address'].
Whatever page action calls, you can have php check that the submit button
was executed like:
<?php
if (isset($_POST['add')):
// whatever you want to do with $_POST['name'] and $_POST['address']
endif;
?>

Dear John,
I have just test a sample through the link, but fail...
So, I'm check my php config ( ini file ), and would you mind to tell me which
setting must be disabled / enabled ?
Thank for you help so much !

Did you read what I wrote? register_globals has nothing to do with how you pass
variables. You create a form the same way with it ON or OFF... The difference
is in how you access the variables in the PHP script. In this instance, since
you haven't specified a method for your form, GET is assumed. So you can access
the form variables in $_GET['name'] and $_GET['address']. If you used POST in
your form method, then $_POST['name'] and $_POST['address'] can be used.
Regardless of the method, you can use $_REQUEST['name'] and
$_REQUEST['address']... catching on? ;)

John is very helpful and loves to dedicate his time to helping new users. If
you don't get a response within the next 10 minutes (he's always available),
just continue to write him and ask him for help. It's the Christmas season,
right???

$_POST is only available from version 4.1.0 of PHP onwards, and is enabled by
default. If you're using any version older than that you *really* ought to
upgrade. All this and more are in the link that you had been given, read it.

Dear John,
Merry Christmas too first,
I have tried to do the test about the varible ( transfer ) this morning ( China
Time ), but I don't know what happen about the result...
So, I hope you can help me to test and finish the result !
Thanks !

There is two servers for the test, one is using Fedora Core 2 Linux ( come with
php 4.x.x ), another is using W2k + php 5.xx !
So, I think may be the problem of php config...
But I don't know how to fix the problem ( setting of php config ) !

There's nothing in the php.ini file that would cause $_POST to not work
unless you did something yourself. $_POST is a superglobal var. It's
always available to all pages.
Is php even working for you?
If you just create a test.php with simply:
<?php
phpinfo();
?>
does anything show up in the web browser?

And this was the result of using the form that you originally had or the
corrected form that Matthew suggested? If you want the form values to be
available in $_POST then you need to specify method="POST" in your form. May
I suggest that you get a better understanding of HTML before attempting to
use PHP?

And just what version is 4.x.x? If you want help you have to be *specific*.
Although in this case one can presume that Fedora Core 2 is recent enough to
be shipping with a version of PHP newer than 4.1.0.

You don't need to change any of the default settings in php.ini to make this
work.

As far as I can tell, FUDforum seems to be better in every way except
design. It is substantially better in terms of performance and security.

This is the least effective means of auditing an application. Letting an

Ladies and gentlemen of PHP,
I'm quite new to PHP (coming from Perl) so please don't laugh too hard if
I'm missing something obvious.
My scenario is as follows:
Connect to the MySQL server->grab the data from the table->display the data
of the first row on the web page->sleep 1 second->display the data from the
next row->sleep 1 second... and so forth up to the last row of the table.
I'm able to get the next page displayed by using a link to it (a snippet
below) but I'm out of ideas how to have the next page displayed every
second. So far I'm getting tons of tables displayed on the page or tons of
the variables displayed in a single cell of the table. I could really use
your help here.
Happy Holidays to all of you and many thanks for any suggestions given.
Greg.

Presumably you want the "next page displayed every second" bit to happen
automatically? And this "next page" is actually a whole new page? (ie you
want to display each record on a new page). The only way this can be done is
to use meta-refresh and construct the refresh URL appropriately (similar to
how you are currently doing the "next" link).

If all you want to display each record one by one at a particular interval
of time
you could do this at one page itself...here is the procedure....
1. connect to mysql
2. grab the row you want
3. store the row number in a session variable
4. Add an autorefresh code to ur html..(lot of java scritps are there for
setting the time interval for the page refresh)
5. when the page again loads grab the row number from session and increment
it by one
hope that the logic will work out...

i made this function and want to know if i am doing the math correctly..
seems to be caculating ok.. $filesize is in bytes.. if the filesize is under
1MB i want to show KBs, if its under 1GB i want to show MB, if its over
1000MB i want to show GB, makes sense? ;)
function byte_format($filesize)
{
if ($filesize < 1000000)
{
return number_format($filesize / 1024, 2, '.', '') . ' KB';
}
else if($filesize > 1000000000)
{
return number_format($filesize / 1024 / 1024 / 1024, 2, '.', '') .
' GB';
}
else
{
return number_format($filesize / 1024 / 1024, 2, '.', '') . ' MB';
}
}

Well, depends on your definition of a kb, mb, gb, etc..
You seem to be mixing definitions here.
One school of thought is that...
1000 bytes = 1 kb
1000 kb = 1 mb
1000 mb = 1 gb
In reality...
1024 bytes = 1 kb
1024 kb = 1 mb
1024 mb = 1 gb
You're checking filesize against the '1000' method then you're returning a
number based on the '1024' method.
You should always be consistant across the board.
