Im talking about file locking during deleting, and moving
files.
Is it possible to perform file locking for these file operations?
If so, can you provide psuedo code.
Thanks

Sure... just acquire the exclusive lock like you would for writing to a
file, but do the delete / move instead. Your apps must actually try to
flock before *every* file operation though if you expect the locking
system to work.

Yes, have your scripts attempt to lock a separate lock file before performing
deleting or moving operations.

I think if you were to actually echo $message here, it should display in the
hidden field as you expect, and hence be passed as part of the form data to
the target script.

Hi David --
When I do that, it creates a problem because it displays a "> at the bottom
of my screen. It is making me crazy! I think it has to do with all the
quotes in the HTML, but I don't know how to deal with it. I have listed the
code below. Do you have any ideas? Thank you for you help.
Monique.

any output of the program that goes to php://stdout.. if from echo, print,
var_dump, code breaking, etc... why? cuz I want to get chunks of output into
variables to make a cache system..
> What is the Big Picture here?
I want to build a cache system and store there not the whole page, but
chunks of the page.. the chunks are started then ended in some point.. all
the output between the start and stop points is a chunk and I want to get it
into variable... that's exactly using ob_start() then ob_get_contents() to
get the chunk data then ob_end_flush()... But, when using ob_* funcs.. when
calling ob_start() all output afterwards is buffered till flushing.. what i
need is to to allow output being transfered imediately but still get the
chunks in variables..
thanks,
Lorderon.

I got a php waring when I upload my file:
Warning: MAX_FILE_SIZE of 200000 bytes exceeded - file [imgpath=mz-n10.pdf]
not saved in Unknown on line 0
In the form I write like these:
<input type='hidden' name='MAX_FILE_SIZE' value=200000>
<input type='file' name='imgpath'>
And my configuration is :
file_uploads = on
upload_max_filesize = 4M
upload_tmp_dir = /tmp
so, what 's wrong? And can I catch the exceeded file error before it is
passed back to the client?

All right.
I know that it exactly does what it is, and can't be really caught directly
since this happens before the script gets control.
After display_errors = off, I can pick it up from error logs.
Thanks all.

Hi there!
Can someone explain the major difference between fgets and fopen? Which is
the best together with plain textfiles? and why?
eof and feof. What's the difF? *don't get it*
When using fget. Is it something special you should think when taking care
of line-breaks? (/n, /r/n ...)
/G
--- End Message ---
--- Begin Message ---
fgets uses the resource created by fopen.
Read the manual:
http://it.php.net/fopen
http://it.php.net/fgets
look at the example:
<?php
$handle = fopen("/tmp/inputfile.txt", "r");
while (!feof($handle)) {
$buffer = fgets($handle, 4096);
echo $buffer;
}
fclose($handle);
?>

Hello all,
Has anyone had an experience with storing sessions in mysql (or sqlite)?
If so, what if any are the performance benefits? Obviously, there
would have to be an extra db query per page... but would that be faster
then opening a text file?
Also, I was trying to post to the php news server, but my messages
weren't showing up. Is it read only? Or just slow?
Cheers,

Speed depends on several factors and I would not comment on it. One of
the main advantages of placing session information in the database is
that your web application can then be clustered more easily. The other
advantage is that if you are on a shared hosting enviorenment there some
measure of additional protection for your session data when it's stored
in the database.
The main disadvantage is that you are complicating your application a
bit and session management errors may become harder to track.

Hi, I have a form which when submitted adds a record to a DB. However if
the user clicks back it resubmits the same record.
I have tried using cache control to no avail :
header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header ("Last-Modified:" . gmdate("D, d M Y H:i:s"). " GMT");
header ("Cache-control: no-store, no-cache, must revalidate");
header("Cache-control: post-check=0, pre-check=0, false");
header ("Pragma: no-cache");
session_cache_limiter("nocache");
I also tried testing for the presence of a submit button so if the user
enters data submits the form and clicks back the page will refresh.
<?php
if ($_POST['submit']) {
echo "<META HTTP-EQUIV='refresh' CONTENT='0; URL=$PHP_SELF'>";
} else {
}
?>
The problem is I need to display a confirmation message after the user
submits, and with this technique the page always redisplays the (empty)
form after submission.
Any ideas?
Steve
--- End Message ---
--- Begin Message ---
Would something like this work....
If($_POST['submit']){//add error checking for whatever critical fields
echo "Thank you for filling out my form.\n";

I can heartily recommend SciTE (http://www.scintilla.org/SciTE.html)
i believe it has the features you desire, plus, there is a version customised
for php, available here http://amip.tools-for.net/SciTE-CVS.exe
btw, there is a GTK+ version so you can use it on linux as well.

I assume by edit you mean change the value to something completely new.
If you are having the user input the new value you 1) must make sure
it is valid input and 2)move it into the array value (maybe set the
array as a session variable so it crosses over to the next page instead
of being re initialized).
Maybe something like:
if(isset($_POST['submit']){
// make sure the input is valid first
$_SESSION['config']['email'] = $_POST['email'];
$_SESSION['config']['meta_author'] = $_POST['author'];
}
if (!isset($_SESSION['config'])){
$_SESSION['config']= array(
'email' => 'E-mail',
'meta_author' => 'Author')
}
<input type = "hidden" name="email" type="text"
value="<?php print $config[email];?>">
<input type = "hidden" name="author" type="text"
value="<?php print $config[meta_author]; ?>">

through the same text field. With buttons etc.
Here's how i call the arrays from the file:
<input name="hiddenfield" type="text" value="<?php print $config[email];
?>"> <input name="hiddenfield" type="text" value="<?php print
$config[meta_author]; ?>">
Is there anything that can let me edit it? I think i will have to edit it
through a form, it might be simple, though it might not be, please help me
out!

Consider the following:
function test() {
static $i = 0;
$i++;
$retval = ( $i <= 10 ) ? $i : '';
return $retval;
}
while( $bob = test()) {
echo $bob . '<br>';
}
You would expect the while loop to go on forever just looking
at the above code. However, what's happening is that when the
empty string is getting returned due to $i being > 10, the while
loop is resolving FALSE when $bob is set to the value of the
empty string.
Is there any way that I can force this not to happen? That the
while loop resolves as FALSE only when the function actually
returns a (boolean) FALSE value?
thnx,
Chris
