Andre, I have checked the $_POST, and THE $_FILES.
I am pretty sure the actual path is not passed. Now you can find the path on
the server in the tmp_name of the $_FILES array.
I have read a few DOM related issue concerning the PATH of the file uploaded in
mulitpart/form-data.
Microsoft: Internet Explorer 7 and later. By default, Internet Explorer does
not include folder or directory path information when uploading files to sites.
So this means the "Clients Browser" is passing the file name NOT the path.
I am sure if you dig around in JavaScript you may find a way to see the value
of that attribute on submit or click.
I have never wanted to know the actual file path from the end user, nor has it
ever been a request for me to do so.
You can however change the ini for upload_max_filesize and post_max_size inside
of your php script at the top.
<html>
<head>
<title>A file upload script</title>
</head>
<?php
ini_set('upload_max_filesize', 8000000);
ini_set("post_max_size", "30M");
$file_dir = ".";
$file_url = ".";
if ( isset( $fupload ) ){
print "path: $fupload<br>\n";
print "name: $fupload_name<br>\n";
print "size: $fupload_size bytes<br>\n";
print "type: $fupload_type<p>\n\n";
if ( $fupload_type == "image/gif" ){
copy ( $fupload, "$file_dir/$fupload_name") or die ("Couldn't copy");
print "<img src=\"$file_url/$fupload_name\"><p>\n\n";
}
}
?>
<body>
<form enctype="multipart/form-data" action="<?php print $PHP_SELF?>"
method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="51200">
<input type="file" name="fupload">

Subject: [PHP] Ftp upload
Hi everyone,
I would like to have a possibility to upload really large files to the
website.
As we all know, the post_max_size parameter is set to 8Mb by default.
However, I see that the ftp_put() function has a "local filepath"
parameter.
And the question is: how can I retrieve the local filepath if a user
browses to the file from his/her PC?
Thanks!

Hi Richard,
Thanks a lot!
So can I let them upload, say, a 700 Mb file via POST or should I
consider connecting to FTP?

Andre,
Anything over 7 MB to me should be done with FTP.
You have a lot of issues with file corruption, length of upload, and bandwidth
on each end.
But you have to remember, I am crazy in the head. "I think that customer
satisfaction is key!!!"

Dear Experts,
Can you please advise how can I detect a string if it is UTF-8 or now
and how can I if possible
convert a string to a utf-8 ?
Here's the string I got from client - client sends it via POST with
urlencode and does apply UTF-8
encoding on the string.
Here's the string I got:
However I do not get the string as a utf-8 (After I do urldecode to the
client POST parameter)
Please advise

Hi Richard,
So, say, they make audiobooks or movies and they want them to be
available as (paid) download. How should they upload it so they
would be in the catalog?

If it's really large data like that, and they have a lot of it, maybe
upload through the network isn't the best way to go. As Andy Tanenbaum
put it "Never underestimate the bandwidth of a station wagon full of
tapes speeding across town" -- maybe there are better, faster, and
more reliable ways of getting the data to the server? Overnight
courier of a huge harddrive maybe faster if there's a lot to get to
the server. Just a thought.

Any clues?
Check the web version of PHP's phpinfo() output and see if it and
the CLI are using the same php.ini file. My guess is that they're
not, and - while the CLI one is set with the timezone - its web
counterpart is missing the flag.
Ok, first off, are you telling me the CLI and the Web versions
reference different php.ini files? I thought they both used /etc/
php.ini...
Secondly, I *did* check the output of phpinfo() from the web with the
exact same results.
Now, the problem is...
I surrounded the date.timezone setting with single quotes.
So, removing the quotes got me what I needed.

Glad you got it fixed. Many distros do it differently. Windows
normally has one php.ini, Ubuntu and derivatives have 2. Other will
vary. Here's mine:
/etc/php5/apache2/php.ini
/etc/php5/cli/php.ini

Depends on the compile-time arguments and such. You can also have
local php.ini files (as in, under your public_html/ directory, et al).
Some installs even scan those familiar '.d' directories for *.ini.
So, for example: /etc/php.d/*.ini .

I'm trying to extract data coming from an exec() call. The exec()
call is performing an ncdump on a netCDF file:
<?php
$filename = "mlab.20110101.cdf";
exec("/usr/bin/ncdump -l 2048 -v wmax ".$filename, $output);
echo "---\n";
print_r($output);
echo "---\n";
?>
This is all fine, however the data comes in with extra information
I don't need, and the data I do need is in a long string format:
Array
(
[0] => netcdf mlab.20110101 {
[1] => dimensions:
[2] => time = UNLIMITED ; // (288 currently)
[3] => variables:
[4] => int base_time ;
[5] => int samp_secs ;
[6] => float lat ;
[7] => float lon ;
[8] => float alt ;
[9] => int station ;
[10] => float time_offset(time) ;
[11] => float tdry(time) ;
[12] => float rh(time) ;
[13] => float pres(time) ;
[14] => float cpres0(time) ;

ncdump doesn't provide an option to suppress the header
information, and as you can hopefully tell, the data I'm looking for is
in one long string at key position 26.
How can I extract what I need from that (wmax) and have it as an
array: wmax = array(5, 5, ...)
This is only one variable. I will be pulling more variables out,
and they all come out the same way as above, as strings. The headers
might change, so I can't simply say ignore the first 0-25 keys and
expect what I need to be at position 26. I need a reliable way of
detecting where the data section starts. And I need to convert the
strings into arrays for each data set.
Suggestions?

Assuming that it is always the second to the last item, then:
$wmax = explode(', ', $output[count($output)-1]);
array_shift($wmax);
print_r($wmax);
--or to search for wmax =
if($array = preg_grep('/^ wmax = $/', $output)) {
$wmax = explode(', ', $array[0]);
}
array_shift($wmax);
print_r($wmax);
May need some more error checking.

Should be -2 :(

Yeah, error checking ...
Can't search for '/^ wmax $/' because it just returns nothing.
Dropping the '$' at the end works.
The array_shift() also drops the first variable because the
explode() call breaks it up as:
wmax = 5, 5, 5.4 ... etc. First value = 'wmax = 5'
And the explode also fails because data is not in $array[0], it's
in $array[30]. Inserting an array_values() to reindex helps.
So as of right now, I'm looking at:
if ($array = preg_grep('/^ wmax = /', $output)) {
$array = array_values($array);
$wmax = explode(', ', $array[0]);
}
array_shift($wmax);
print_r($wmax);
The array_shift() call needs to shift out the 'wmax = ', but leave
the first value.
And, I still need to convert the whole thing into '$wmax = {5, 5,
5.4, ...}'. Right now it's an array of strings:
Array
(
[0] => wmax = 5
[1] => 5
[2] => 5
[3] => 5.4
)

Sorry, didn't have a way to test when I posted. So you've posted two
different expected outputs and I misread the first. You want a string
of only the coma separated numbers? If so:
if ($array = preg_grep('/^ wmax = /', $output)) {
$wmax = array_shift($array);
}
If you want to get rid of the wmax = or add the { } or whatever use
str_replace() and/or concat then on.

Seems what's best here is to do two explodes:
$matches = preg_grep('/^\s*wmax/',$inputdata);
if (count($matches) != 1) die("More or less than one wmax in data
set");
$wmaxline = end($matches);
list($var,$data) = explode(' = ',$wmaxline);
$data = substr($data, 0, -2);
$wmax = explode(', ',$data);
print_r($wmax);
which gives me the result of an array of data values.

[0] => 5
[1] => 5
[2] => 5
[3] => 5.4

I do that using an external tool pdf2png. For me, I use Cygwin.
Works very well for me. Also splits the PDF into single page per PNG.
I can then process the PNG files in other ways.

Can you see what pdf tools ARE installed?
Are the PDFs text based or just images in a PDF file (mine are both),
but for just images, you _COULD_ extract the image data manually.

The PDFs are text only (white text on transparent background). I made them
using the FPDF, which was tedious to set up but works great. I've since learned
that I need PNG images, not PDFs. I know that I could rebuild them using GD,
but it's a lot of strings of text wrapping and formatting and that would be the
long, long way around.
I've put in a request to see about getting ImageMagick/Ghostscript installed...
see how that goes.
