Thanks for your replies.
1. Did you put the enctype="multipart/form-data" into the FORM tag?
Ans: I do not have a form! I'm using a gateway utility to upload files
From documentation of Mbuni MMS gateway:
post-url
Response content is obtained as result of sending a HTTP POST request to the
provided URL. The POST message is *always* encoding (such as that used by a
web browser when an HTML form has the submitted using the
multipart/form-dataenctype=multipart/form-data parameter set). If
http-post-parameters field is given (see below), then the relevant
parameters are sent as part of the request. *X-Mbuni* headers are sent as
well.
http-post-parameters
Used in conjunction with post-url. Parameters are provided in the same way
as would be provided in an HTTP GET request (e.g. *
message=true&myname=test&image=%i*).
2. Have you tried simply saving $_POST['userfile'] to a file?
$save = $_POST['userfile'];
$f=fopen($out,'a');
copy($save, $out);
Files don't go into $_POST - they go into $_FILES.

Files don't go into $_POST - they go into $_FILES.
Yes, his problem is that the $_FILES is not being set, but
there is some value in $_POST['userfile'].
Kartikay, I was suggesting that $_POST['userfile'] may
contain the file itself, not a filename. What does
$_POST['userfile'] contain? Try var_dump()ing it.

Is there a file size limit in kb for Blobs and what is it?
What size of file can a LONG BLOB accomodate?
If it is not this any ideas? It seems to fix it though!
Let's not even attempt to pretend that this question has anything
remotely to do with PHP. mmmKay?

I believe it depends on compile-time settings, but this is really a
MySQL question...
It's probably 4 Meg or something.

Probably twice as much as a regular one.

It will only fix it for PDFs up to the size of a LONG BLOB, whatever
that is.
The REAL fix, imho, is to stop abusing your database for large file
storage, and use the custom highly-optimized large file data storage
engine commonly known as the "file system"

Yes, I was wondering that myself considering the onslaught of "no-no's" one
gets by suggesting placing images into a dB. A PDf file is really not that much
different and probably better served via file system.

Yep, then tried some weird stuff and it worked :-)
INSERT INTO test2
VALUES (Curtime(), DATE_ADD(Now(), INTERVAL '5'
minute));
Maybe this will help someone else out.
Thanks for trying though.

Hi there,
I am reading a remote plain text file from another server via the file
command:
$str = file ("http:/xxxxx");
This is a feed so there is no other way then reading it remote.
Now this reading takes up between 0.5 and 1.0 s which is far to slow.
The whole other process on the site takes only 0.1 s and I would like to
keep it inside this area of 0.1 - 0.2 s
Is there a faster way to read a remote txt file than with file() ?
If not, is there a way in php to process this in the background and
continue to display the page without the results of the file?
Thank you in advance,
Merlin

not sure on a "faster" way, but you can have PHP handle this on the
backend without disrupting the normal page load time...
Enter AJAX...
Set a side a place on your page for the results, and on page load issue
an AJAX request to a backend process to get your contents from the file,
and when it is done, your page can display at that point in time.
Fairly common usage for AJAX, so there should be some good tutorials out
there which google will help you find.

It's said on the manual that
file_get_contents() is to be used if you want to read a text file.
from the manual :
"file_get_contents() is the preferred way to read the contents of a
file into a string. It will use memory mapping techniques if supported
by your OS to enhance performance."
The loading speed may be also affected by the time your server needs
to access the remote server.
If the information is not updated really fast, you may create a
cronjob to run every N minutes, and fetch that file on your server,
than make your site access the local version of the file, that will
effectively remove the network lag...
--- End Message ---
--- Begin Message ---
As I believe someone else said, file_get_contents() is the perfered way.
Bare in mind however that reading off a network will probably be slow
compared to other operations.
This of course depends on the speed of your network, and the complexity of
the other operations.

What, exactly, are you measuring on that "other side"?
Think carefully about this.
Because odds are really good that you ONLY measure the time for some
process to spit "out" the data.
Yet, there is a great deal more time being spent on the "other side"
For example, if this "other side" has PHP and Apache, and you ONLY
measure the PHP start/end times, you're ignoring any Apache overhead.
How fast/slow is, say, wget from the local server?
That's probably a much more accurate measure to compare your PHP
performance with.
> Is there a faster way to read a remote txt file than with file() ?
Since file() has to read each line and build up an array, it might be
slower than http://file_get_contents
> If not, is there a way in php to process this in the background and

You can use asynchronous streams/sockets to get the process started at
the beginning of your script, do other stuff, and then get the results
at the end of your script.
You could also use something browser-side like XmlHttpRequest or
full-blown AJAX to have the browser download the feed "later" --
Though even a iframe could do that, much simpler, most likely.
I would not be too hasty jumping into the iframe/ajax/client-side
solution, personally, as it tends to open up cans of worms.

Hi Folks,
Should be a nice easy one - if running PHP5, how do I add more than one
exec_dir into the list? i.e. what is the separator?

I have never used the directive but I imagine it hasn't changed between
php4 and php5 ...
and I would hazard a guess that the dir seperator is the same as for
open_base_dir

Hi,
I have a form in which a drop down field is populated from a MySQL database.
I am also using sessions.
The problem is this. After I submit the form the session variable only shows
the part of the input before the space.
Example: if I choose Niagra Falls from the drop down list, then I only see
Niagra when I display it.
I'm not sure though if it is the session or the forms variable that is
causing the problem. I haven't been able to find much on this.
See code below....
Thanks
session_start( );
......Open database and connect to server.......
Include("connect.inc");
!! Start of form !!
<select name="province">
<option selected>-- Select Province --</option>
<?
$query = "select pid, location from province order by location"; $results =
mysql_query($query) or $mysqlerror = mysql_error(); if ($mysqlerror) {
$dberror = "Messed Up";
include("index.php");
exit;
}
while ($line = mysql_fetch_array($results)) {
if($line['pid'] == 1) {
echo "<Option
Value="$line['location'].">"$line['location']."</option>\n";
}
}
</select>
!! Rest of Form !!

Perhaps you should load up your initial form and then use the "view

into your problems...

Not sure why I would get a parse error, but that did correct the problem. I
just completely missed the single quote. I never even clue'd in when I
looked at the source of the page.
Sometimes another pair of eyes does the trick. Maybe it's time for a break.

Hello,
for ($i=0; $i < 10; $i++) {
$output = "ccc2";
print "<pre>";
echo $output;
print "</pre>";
ob_flush();
flush();
sleep(1);
}
I want to show on the browser, "ccc2" (example) every 1 second, but it
shows all the text when the for stops... any ideea?
i tried all the examples from php.net, all the examples on the net,

PHP is a server side scripting language, so the information would not be
sent to the browser( aka client) until the server side script has
completed its execution.

That is incorrect. There is nothing stopping a PHP script from doing
exactly what he says, and being a server-side script doesn't imply that
the data will be buffered.
I suggest that both of you examine the contents of
http://www.php.net/manual/en/function.flush.php for more information on
obstacles to getting data to the client as it is generated.
As an unrelated note, there is no point in using "print" for some things
and "echo" for others. For your uses, you might as well just use "echo"
for everything.

ob_flush() only makes sense if you have ob_start() somewhere, or if
output_buffering is enabled in php.ini
flush(); and sleep(1); are all you should need...
At least from PHP standpoint.
But there are many other players outside the control of PHP...
Apache could be buffering output.
TCP could be buffering output.
Your browser will NOT render some parts of some elements until the
tags are all closed -- If you are inside a TABLE, for instance, expect
not to see things happening in real-time.

This is just plain incorrect.
While buffering within various pieces of software MAY alter the
timing, data IS output from PHP as it runs, not only after execution
is completed.
If you pump ENOUGH data out, and then sleep(10) and then pump ENOUGH
more data out, you WILL see the data in parallel with script
execution.

I was about to write code to recursively list the contents of a
directory when I remembered seeing an object in SPL that would do it for me:
http://us3.php.net/manual/en/function.recursivedirectoryiterator-next.php
But there is no documentation on this object, and although I have it in
PHP 5.1.4, docs say it's might be only in CVS. So, I try using it and
get this:
<?php
$dir = new RecursiveDirectoryIterator("/some/dir/path");
while($dir->valid()) {
print $dir->current()."\n";
$dir->next();
}
?>
But it doesn't seem to recurse through the directories. In fact, this
acts just like DirectoryIterator. So, there must be a flag to make it
recurse, but documentation is not there. I see this documentation here:
http://www.php.net/~helly/php/ext/spl/
But that just looks like the source code was parsed to generate it,
nothing much help in seeing an example of the usage.
Is SPL meant to be used? If so, is it experimental? Is it documented?
Should I stay away from SPL for production code? What's the official word?

http://php.net/manual/en/function.recursivedirectoryiterator-haschildren.php
and related methods...
also take a look here:

try looking at the userland version of the SPL classes they give quite abit
away as to how they work and how you can use them.

yes it's meant to be used, yes you can use it in production BUT your
a little on the bleeding edge (not very many people using it full on) AND
the whole of SPL is still a little in flex (as is php5->php6 in general) so
that you may be forced, occasionally, to adapt your code to changes (e.g.
constants that were formally used in SPL are now class constants.)
and please note this is not the official word but jmho.

Wow, this is some magical stuff. Here is my function in case it's of use:
//----------------------------------------------------------------------
/**
* Magical SPL code to recursively list files in a directory
*/
public static function get_paths_recursive($start_path) {
$paths = array();
$rdi = new RecursiveDirectoryIterator($start_path);
foreach (new RecursiveIteratorIterator($rdi) as $path) {
array_push($paths, (string) $path);
}
return $paths;
}
//----------------------------------------------------------------------
This iterates over objects like arrays, casts objects as strings, and
iterates
iterators. All sorts of fun and joy enough to make your head spin.
Seems to
work, though ;-)
Thanks for the wiki doc link, Jochem.
