Hi, Could it have something to do with an eof character being encoded or

Hello,
I am trying to create an UPLOAD page to Update a Images and PDFs into a
BLOB field in mySQL. The image keeps getting corrupted (it draws a portion
of the image and the rest is GRAY) We tried it with Safari and Firefox with
bad results.
Here is the form that is used to browse and select the file.
!-- Upload Image dialog --
div id=uploadImage
div id=llback/div
centerdiv id=uploadForm
div id=uploadTitleUpload Thumbnail image/div
iframe name=saveImage/iframe
bPlease select the thumbnail image, then press Upload./b
div
style=margin-top:14px;margin-bottom:14px;text-align:center;width:100%
form target=saveImage method=post action=ajax/saveDialog.php
enctype=multipart/form-data
Select Thumbnail: input type=file name=img id=img
accept=image/jpeg //div
input type=hidden name=obj value=uploadImage /
input type=hidden name=id value=?php echo $Area_id ? /
input type=button value=Upload
onclick=saveDialog('uploadImage','img','jpg'); input type=button
value=Cancel onclick=cancelDialog('uploadImage','img')
/form
/div/center
/div
Here is the QUERY to upload the image (saveDialog.php):
if($_POST['obj'] == uploadImage) {
$file =
$db-real_escape_string(file_get_contents($_FILES['img']['tmp_name']));
$db-query(UPDATE Areas SET Image = '$file') or die(1.$db-error);
Has anyone else ever run into this type of UPDATE error with images and
PDF? We really need to get this dealt with ASAP.
Thanks!

Like someone mentioned on the link you posted; storing the images in the
database does offer a layer of security, as database access is far
easier to control than file access.

[PHP] this has got me baffled: imagesx() and imagesy() reporting the wrong size?
On my site I have a web form for users to upload graphics, however there
are constraints on the size allowed. Recently, a user has been having
problems, because the code is reporting the wrong size - a size too
small to be allowed! They sent me a copy of the image so I could
confirm the error, and I have: even though the image is a 32x32 image
(2-frame animated GIF, if it matters), imagesx() and imagesy() report
that the image is 30x24! I have never had this problem before (or, at
least, no one has reported it to me) so I'm tempted to think that it's a
bug in PHP, or (more likely) I am missing something crucial...
The relevant code:
if($itype == 'image/gif')
$img = imagecreatefromgif($_FILES['file']['tmp_name']);
else if($itype == 'image/png' || $itype == 'image/x-png')
$img = imagecreatefrompng($_FILES['file']['tmp_name']);
// note: we do not get here if($itype != 'image/gif' $itype !=
// 'image/png' $itype != 'image/x-png'), so the problem should not
// lie with an image type we were not expecting
$w = imagesx($img);
$h = imagesy($img);
if(!(($w == 48 $h == 48) || ($w = 4 $w = 48 $h == 32)))
{
$error = 'The graphic\'s dimensions are not correct (' .
$w . 'x' . $h . ').';
}
else
{
...
}
yes, the logic wants either a 48x48 graphic, or a 4x32 to 48x32 graphic.
I'd be happy to link the animated GIF in question... just in case there
was a problem with the GIF itself, I tried opening it up in an (old)
version of Fireworks, and re-exporting it, but the problem remains.
besides the possibility of a bug in PHP, I'm wondering if I need to
handle animated GIFs differently, or something like that? but again,
this code has been running for... 3ish years without a problem like this
ever being reported... quite confusing.

If you could link the gif I think that would help.
Also, just to point out, the comment in the script is wrong, if the
image is neither png or gif, the rest of the script will still be
parsed. The if logic is like this:
if($itype == 'image/gif')
$img = imagecreatefromgif($_FILES['file']['tmp_name']);
else
if($itype == 'image/png' || $itype == 'image/x-png')
$img = imagecreatefrompng($_FILES['file']['tmp_name']);
everything after that is executed
perhaps you wanted something like this:
if($itype == 'image' || $itype == 'image/png' || $itype ==
'image/x-png')
{
if($itype == 'image/gif')
$img = imagecreatefromgif($_FILES['file']['tmp_name']);
if($itype == 'image/png' || $itype == 'image/x-png')
$img = imagecreatefrompng($_FILES['file']['tmp_name']);

[PHP] Lightweight web server for Windows?
What do people on this list use as an ultra-lightweight web server (with PHP capability of course) on Windows? I have an old but still well functioning laptop that I have just given a second life by installing Windows Fundamentals (a stripped down version of XP). This works surprisingly well. So now I am looking for the necessary software, so I can do some local programming. Some requirements I can think of: - Extremely small memory footprint and fast efficient code. This laptop still works well but it can certainly use some help! - Both free as in beer and free as in speech would be my preference. - Be able to run as a service in XP. - Be able to run PHP (obviously) and perhaps a few other nice server features, like SSI and name based virtual hosts. Any suggestions? I have not seriously used Windows for years now, so my knowledge of that platform is not exactly up to date anymore. I am used to dealing with Debian/Ubuntu Linux and Apache but not much else, frankly. Apache does seem to heavy for this. My initial thought was to install Lighttpd under Cygwin, but perhaps I would be missing out on some great little server program that I have not yet heard about. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

what I meant by the comment, is that that previous code DOES exist... to
assure you that the problem isn't in having $img unset, or something
along those lines. (I added in the comment after the fact.)
I have uploaded the image causing the problem here:
www.telkoth.net/temp/radioactive-bread-eek.gif
I should also add: I have ended up working around the problem by using
getimagesize() instead; that function is reporting the correct width and
height. this furthers my belief that there's a bug somewhere with
imagesx(), imagesy() or imagecreatefromgif()...

Maths really isn't my strong point and formulas go over my head otherwise I wouldn't ask :-( Thanks everyone Chris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hello,
I am trying to create an UPLOAD page to Update a Images and PDFs into
a BLOB field in mySQL. The image keeps getting corrupted (it draws a
portion of the image and the rest is GRAY) We tried it with Safari and
Firefox with bad results.
Here is the QUERY to upload the image (saveDialog.php):
if($_POST['obj'] == uploadImage) {
$file = $db-real_escape_string(file_get_contents($_FILES['img']
['tmp_name']));
$db-query(UPDATE Areas SET Image = '$file') or die(1.$db-error);
Random ideas:
* Select the image from the database and compare it to $file.
Are they identical?
* Run a hex dump on the images before and after upload.
What is the difference?

$size = 1024548756; // in bytes
$kb_per_sec = 60; // I assume you'll fill these in from elsewhere?
$b_per_sec = $kb_per_sec * 1024;

if($seconds 60)

You could also approach this using modulus, but if you're not confident
with math, this might be a more intuitive approach.

Re: [PHP] Help needed with calculation
If the download speed is constant (linear) then you can just use. (10245458756 / 6t)/1000 = kb/second or (10245458756 / 6t)/6 = kb/minute The general form would be. (size_of_file / download_speed * time) / convert_to_units Where t (or time) is the amount of seconds that the download has been active.

yes, the logic wants either a 48x48 graphic, or a 4x32 to 48x32 graphic.
I'd be happy to link the animated GIF in question... just in case there
was a problem with the GIF itself, I tried opening it up in an (old)
version of Fireworks, and re-exporting it, but the problem remains.
besides the possibility of a bug in PHP, I'm wondering if I need to
handle animated GIFs differently, or something like that? but again,
this code has been running for... 3ish years without a problem like this
ever being reported... quite confusing.
If you could link the gif I think that would help.
Also, just to point out, the comment in the script is wrong, if the
image is neither png or gif, the rest of the script will still be
parsed. The if logic is like this:
if($itype == 'image/gif')
$img = imagecreatefromgif($_FILES['file']['tmp_name']);
else
if($itype == 'image/png' || $itype == 'image/x-png')
$img = imagecreatefrompng($_FILES['file']['tmp_name']);
everything after that is executed
perhaps you wanted something like this:
if($itype == 'image' || $itype == 'image/png' || $itype ==
'image/x-png')
{
if($itype == 'image/gif')
$img = imagecreatefromgif($_FILES['file']['tmp_name']);
if($itype == 'image/png' || $itype == 'image/x-png')
$img = imagecreatefrompng($_FILES['file']['tmp_name']);
// execute the rest of the image checking script

what I meant by the comment, is that that previous code DOES exist... to
assure you that the problem isn't in having $img unset, or something
along those lines. (I added in the comment after the fact.)
I have uploaded the image causing the problem here:
www.telkoth.net/temp/radioactive-bread-eek.gif
I should also add: I have ended up working around the problem by using
getimagesize() instead; that function is reporting the correct width and
height. this furthers my belief that there's a bug somewhere with
imagesx(), imagesy() or imagecreatefromgif()...
It does indeed seem to be some sort of bug. I've just tested it with
your image on my machine here and for imagesx() and imagesy() it gives
30 and 24 respectively. getimagesize() does return the correct
dimensions though.
The same image saved as a flat single layer gif from the Gimp behaves
exactly the same way.
This might not be a proper bug as such, as the image itself might be
32x32, but the first layer (the first frame in the animated version) is
30x24 when you remove the dead, unused, transparent background. Perhaps
GD is meant to report on the *actual* size of the image, rather than the
dimensions of the frame?

! interesting (that it's doing some kind of trimming). it hadn't
occurred to me that it might be doing that. if that's the case, and
intended behavior of these functions, I feel like it should definitely
be mentioned somewhere on php.net

[PHP] Re: mail mimedecode with multiple mails in one mbox file
Hello, on 11/15/2009 05:22 PM Ashley Sheridan said the following: Hi all, I'm having a bit of difficulty seeing my way through this. I think I'm on the right path with mimeDecode, but I can't get it to read all of the emails in an mbox file which contains 100 emails; it only reads the first. I've looked over the docs on pear.php.net, but can't seem to find any way to get the other 99 emails out! Does anyone know of any way to do this, or have you done something similar another way? Just to clarify, I won't be connecting to an external mailbox for this, so it has to be something I can use on a local mbox file. The mbox format is not exactly compatible with the regular MIME message format. Anyway, you may use the MIME parser class which supports parsing single MIME messages as well multi-message messages in the mbox format. Just set the mbox class variable to 1. http://www.phpclasses.org/mimeparser -- Regards, Manuel Lemos Find and post PHP jobs http://www.phpclasses.org/jobs/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Lightweight web server for Windows?
Try nginx (http://nginx.net/), very light, has a Windows binary distribution and can be configured easily for PHP. You can also find some version of Lighttpd compiled for Windows and skip the compilation troubles, and you can use this: http://sites.google.com/site/lightytray/ to control the webserver. Both of them are lighter than Apache. Good luck, Jonathan On Sun, Nov 15, 2009 at 6:00 PM, O.
