In my File Upload form, if the file is >=2MB, the user just gets a
blank "error opening file" screen, almost immediately after the
upload starts. I don't know how to trap for this to give a more user-
friendly experience. Can anyone point me in the right direction?

are you using PHP 5? If so, maybe check out this, below.

Ok, just checking (I am new to the fopen() function). That makes
sense. Awesome, thanks!

Hi,
Indeed a fclose($fp) is needed (wrote it as an example :)).
1MB is more than enough as a buffer. If you have a 53MB file,
what will happen then ?
I have no idea if it's a bug or a feature. Either way I did lose
some hair over this when I switched from PHP4 to PHP5.

Catalin,
Wow, that worked great, thanks.
I'm curious why you set a static buffer of 1024768... why not
just do filesize($file), as shown at http://www.php.net/fread ?
Is it better for memory usage to have a potentially smaller
buffer? Also, you may want an fclose($fp) after the file has
been downloaded.
So is this a bug in PHP 5 or are they just purposely limiting
the abilities of the "readfile" command?

Hi,
I've had a similar problem. The download always stopped at
exactly 2.000.000 bytes.
You have to work around that with:
$fp = fopen($file, 'r');
if($fp) {
while(!feof($fp)) {
echo fread($fp, 1024768);//see the huge buffer to read into
}
} else {
//whatever error handler
}

Hello all,
I am new to this list and I have searched the archives to no
avail. I am having a peculiar problem when upgrading to PHP 5:
My downloads are now limited to the first 1.9 MB of the file
in question, with the download either terminating at 1.9 MB
or seemingly continuously stuck in a downloading process at
1.9 MB. The code in the PHP script has not changed and all
parameters that I could find that are relevant to this
problem are given below:
the minimal code needed for download:
// $file_to_read is the complete path of the file to
download
header("Content-Type: application/pdf");
header( "Content-Disposition: inline; filename=
\"$filename \"");
$len = filesize($file_to_read);
header("Content-Length: $len");
@readfile($file_to_read);
php.ini file for both php version 4 and 5 contain the
following settings that may be relevant:
allow_url_fopen = On
max_execution_time = 300 ; Maximum execution time of each
script, in seconds
max_input_time = 300 ; Maximum amount of time each script
may spend parsing request data
memory_limit = 8M ; Maximum amount of memory a script
may consume (8MB)
post_max_size = 200M
upload_max_filesize = 200M
Some additional details:
All files less than 1.9 MB download fine
It is not a corrupted file, because all files larger than 1.9
MB fail after 1.9 MB
The connection is not timing out (download of 1.9 MB takes
only ~15 sec)
Mac OS X 10.3.9 with Marc Liyanage's PHP 5.0.4
Fails for both Safari and Firefox
Fails regardless of "inline" or "attachment"
Fails regardless of "pdf" or "ppt" content-type
This PHP code ALWAYS works for Marc Liyanage's PHP 4.3.4 with
the same settings, above
What am I doing wrong??? Any other parameter in php.ini I
should have set? Any suggestions are much appreciated.
thanks,
Jordan

Add it to a list (flat file, DB, whatever) of processes to be done and
run a cron script regularly (how regular would depend on the specific
app) to execute all the processes in the list.

echo ereg_replace( '^.*/', '', $_SERVER['SCRIPT_NAME'] )
ereg is greedy, it'll match as much as it can.

Hi all,
I'm trying to get started in OOP with PHP. I have the following
short code snipped. I'f I comment out the 'class Test' definition and
the following references to it, it prints
This is outside the php code block
and
Start defining the class here:
If I do not comment out the code as noted, then the page returned is
totally blank. It does this with or without using the constructor.
PHP 5 on apache. Same behavior both on Win32 and FC4.
All help appreciated to get me going.
Code Snippet:
<html>
<head>
<title>PHP Class testing</title>
</head>
<body>
<br>
<P>This is outside the php code block</P>
<br>
<?php
echo "Start defining the class here: <BR>" ;
/* class Test
{
function __constructor()
{
var $saying ;
$saying = "Im in the Test Class" ;
}
function get()
{
return $saying ;
}
var $liveclass ;
$liveclass = new Test ;
echo $liveclass->get() ;
echo "<BR>" ;
echo "This is in the php code block" ;

Try removing the /* and */
Other than that, check your brackets.
you never closed the get() function's

Sorry.. 1 more thing.
php5 does not use var.
use public $variable=value; instead.
public is only within a class however. you cannot use it outside.

Here is the working code
You had __constructor() it's __construct()
notice I also moved your saying declaration outside of the constructor.
this is to make it a class level variable.
the way that you had it set it was only in scope until you finished the
construct code.
I guess I was wrong about the var bit. I do remember having lots of issues
with it back a few months ago. perhaps theses were fixed in newer versions.
most likely var is depreciated in php5. (can someone confirm this?)

Bob,
'wrapping' you class definition within HTML like you have done is
not only weird but down right ugly. I recommend sticking each class
you write in a seperate file and using include_once() or require_once()
before you output anything to the browser. basically try to
seperate you code into 'stages' (for want of a better word) e.g.:
1. setup an environment (includes loading classes)
2. process the request
3. redirect or output a page

'var' doesn't belong here. it belongs directly in the body of class def.
$saying = "Im in the Test Class" ;
}
function get()
{
return $saying ;
there is a missing '}' here.
also you should be returning and setting $this->saying
}
var $liveclass ;
drop the 'var' - it's only for php4 and then only for
defining the properties of classes/objects:
class Test {
var $myProperty;
}
$liveclass = new Test ;
echo $liveclass->get() ;
echo "<BR>" ;

Hi
As a security precaution, all uploaded files are automatically deleted when
the script goes out of scope.
Use the move_uploaded_file function to move the file somewhere else before
your script ends.
There are various other security precautions you have to consider. And by all
means don't expect the browser to adhere to the limitations you set in the
form, like mime type and max sizes, also know that it is fairly easy for
someone to directly connect to the socket and upload a file, bypassing the
browser altogheter.
The php documentation site covers file uploads in depth (www.php.net)
HTH
With kind regards

Hi
While it *is* possible to do what you ask for, it would be worthless.
I can write from scratch a php script that
* looks up the mx record for a given email address
* connects to the mail server looked up
* send the message.
Since the SMTP protocol is fairly simple, I am sure many others can and will
use this to circumvent your limitations.
With kind regards

Hi php-general,
I'm interested to know what everyones preference is for user
permissions / roles in php apps? For example do you employ a Unix
style groups system, is there a ready-rolled class or package you
use, or have you just built your own and stick with it?
Cheers,
Rich

What I do is have different classes that build upon each other,
authentication & permissions class,
common database access extending PEAR DB.
then i have a custom class for specific actions like editing pages, my
database is just either either an email or username and password then
another table has permission levels in, permissions for every user are
defined in their DB table in a comma seperated list, that way i can
create many groups and have a user belong many groups, then page editng
for instance can be restricted to specific users or groups, I designed
it all to be flexible enough to reuse for all my websites I hope :)
Regards,
James
