Re: [PHP] Is it possible???
Hi, Shouldn't it be: $item_amount_in_store = 223; $update_amount = 7; $item_amount_in_store += $update_amount; $update_amoint_in_store is now 227; The 3rd line seems wrong as you didn't use the same variable. -- Raphaël Khaïat 06.72.89.57.29 On Mon, Jun 24, 2013 at 1:59 PM, Karl-Arne Gjersøyen wrote: > $item_amount_in_store = 223; > $update_amount = 7; > $update_item_amount_in_store += $update_amount; > $update_amoint_in_store is now 227; > > Why?

Because you're using $item_amount_in_store and $update_item_amount_in_store as if PHP should know you mean the same thing. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Is it possible to click download button,and run 2 tasks downloading a file and show number of downloads(ajax)simultaneously?
oh my bad:)! there is a cool solution,I forgot the blank page!:) yep!
solved:)
window.open('download.php', '_blank' );
now I can count up,and download:)
$(".button").click(function(){
var id=$(this).attr('id');
var dataString = 'id='+ id ;
$.ajax({
type: "POST",
url: "download_number.php",
data: dataString,
cache: false,
success: function(html)
{
$("#div_"+id).html(html);
} });
window.open('download.php', '_blank' );
});
so cool!!:)

Re: [PHP] Is it possible to click download button,and run 2 tasks downloading a file and show number of downloads(ajax)simultaneously?
Thanks Tedd,
ajax works fine now,when submiting a button it will show the number and it
doesn't have any problem
$(function() {
$(".button").click(function(){
var id=$(this).attr('id');
var dataString = 'id='+ id ;
$.ajax({
type: "POST",
url: "download_number.php",
data: dataString,
cache: false,
success: function(html)
{
$("#div_"+id).html(html);
} });
}
button:
div:
by the way* I totally will refuse this approach* because,although the ajax
is working,but I can't do anything for click to download the related file
because when I go to my php page I can't redirect it to a page for download
and besides echo the output to be written in div element,so that,the best
solution is just redirect to a page and download the file in first place.
after submiting write a $_POST['submit'] and just store the download
count,update the table and if user refreshed the page,can see the number of
downloads,*as sure there isn't anything better than this.*
Marco suggested me iframe,reloading it,like a manual ajax but I think it
has much of troubles.
by the way thanks for all helps.

On Oct 14, 2012, at 7:41 AM, Negin Nickparsa wrote: > I wanted to refresh the download count when clicking the button first is it > possible? Yes, it is possible. The following is an example of a server-side php script refreshing a Web page via a javascript client-side action: http://php1.net/a/zipcode-states/ The action is triggered by simply using the selection control, which in turn activates an onchange javascript routine that causes a slave php script to run retrieving data from a database returning the data thereby causing an ajax script to update the selection control. All the code (html, javascript) is there except for the php script, which should be trivial to write.

Yeah, but n the context of wordpress, that does not fly.

This is not a WYSIWYG editor question; WYSIWYG editors are things
like KompoZer, Dreamweaver, FrontPage, and even web-based things like
TinyMCE, et al.
That aside, try this very basic example (and expounded) and see if
it's what you're trying to achieve:
';
if (isset($_GET['title'])) {
echo $_GET['title'];
} else {
echo 'The title has not been set!';
}
echo ''.PHP_EOL;
echo 'Change
Title'.PHP_EOL;
?>

It probably does way so much more than I need or want and I think I can do everything that I can on Apache. IIS7 is certainly a massive leap ahead of the PWS I first tried to use. IIS+FastCGI+PHP. Add the Rewrite plugin and the PHP extensions WinCache and SQLSvr (PDO if you want it) and you have a well defined simple setup. Obviously, getting to grips with the administration UI is a bit different to just editing a plain text config file, but IIS does use an XML file for its config, so, once you know the xsd, you can do that by hand also. Full docs on the xsd are available online, so really, I'd guess in terms of ability, IIS and Apache are on-par.

RE: [PHP] Is it possible to send POST vars through a header redirect?
I thought the question was pretty straight forward. Sorry about that. As
someone mentioned, yes I'm just trying to hide the var from the user. What I
meant by I don't want it to stick with the session, is that I don't want it
to be available from page to page. I want my script to run and redirect with
the var to another page without the user seeing it. Currently, I am using
GET and
header("Location: http://domain/?somevar=somevalue";)
I'll try some of the previous responses thanks for the help.

Well, since the OP can't POST using header, then maybe alternatives to
help them out?
If you want to use sessions or are already using them (i.e.
session_start() on each of the pages), you can just use session vars:
session_start();
$_SESSION['var'] = 3;
header("Location: http://domain/index.php";);
exit;
Then in the next page you have the var:
session_start();
$var = $_SESSION['var'];

Re: [PHP] Is it possible to send POST vars through a header redirect?
Not possible to send POST in header if your aim is to hide vars from users. Could think about dynamically send POST using Javascript. form.send(); This requires some JS knowledge about how to exchange data between PHP and JS 2009/2/4 tedd > At 9:47 AM -0500 2/4/09, Mike Roberts wrote: > >> Ladies and Gentlemen. >> I am a recruiter who joined this list to understand a little about PHP.

I'm trying to send vars via POST somehow. Is this possible?
Currently I'm doing

but, want to send POST or some other method that doesn't stick with the session.

I second that you need to use curl:
$header = array(
"MIME-Version"=>"1.0",
"Content-type"=>"text/html; charset=utf-8"
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $this->elqPosturl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, $this->curlOptTimeOut);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($ch, CURLOPT_PROXY, $this->proxyServer);
curl_setopt($ch, CURLOPT_PROXYPORT, $this->proxyPort);
curl_setopt($ch, CURLOPT_POSTFIELDS, $inputArray);
curl_setopt($ch, CURLOPT_USERAGENT, 'MSIE');
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_HEADER, 1);
$data = curl_exec($ch);

DOH!. I'm sorry I didn't read the fact that this was on Windows. My bad...

wrong. Not to start an OS religion war, I use XP all day long, but I would
never use it as my dedicated web server -- that's why God invented
Unix/Linux. Best tool for the job and all that stuff... You're just asking

RE: [PHP] Is it possible to restart Windows Apache (service) on a PHP script?
What we do is setup 'sudo' to run certain commands (or a shell/ruby script
for example), then have PHP/Apache exec() the script via sudo (or use a DBUS
call to a 'root' enabled ruby daemon), which then restarts apache or
whatever we want.
Be VERY careful with the way you do this or you can give crackers all kinds
of ways to cause you pain.
For example:
[EMAIL PROTECTED]:/etc# cat /etc/sudoers
Cmnd_Alias CHMOD = /bin/chmod
Cmnd_Alias REBOOT = /sbin/reboot, /sbin/shutdown
rootALL=(ALL) ALL
www-dataALL=NOPASSWD: /bin/date, /sbin/hwclock,
REBOOT, /usr/bin/dpkg, /usr/sbin/chpasswd,
/usr/bin/passwd, /usr/sbin/srvwatch,
/usr/sbin/srvtalk
Then in the PHP web page:
exec("/usr/bin/sudo /sbin/reboot");

"Voice or no voice, the people can alway be brought to the bidding of the
leaders. This is easy. All you have to do is tell them that they are being

Re: [PHP] Is it possible to restart Windows Apache (service) on a PHP script?
You could try using exec to set up an "AT" job with a short delay which will
then run 'net apache restart' - I'm not a total windows guru so I can't give you
the exact recipe...
Something like exec('AT 12:00 "net apache restart"');
Check the documentation on the AT command...
One possible extra advantage is that you could cancel the 'AT' job during the
delay period if you clicked restart by accident :)

You can try to use all the zillion header calls people will send you. Somewhere out there is a really stupid browser that will insist on caching it. src="somebody.jpg?" will make it very difficult for any halfway-decent browser to cache. However, that can lead to some issues when the URL of the image is embedded elsewhere, as some folks will strip off the GET arg on the assumption that it's invalid for a JPEG. Embedding the random bit so that it LOOKS like a directory, but isn't, will avoid that problem.

Well, this is only one specific image that constantly changes, the rest of
the page is handled regularly.
From what you've said if I go with this
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
That will effect only the one specific image I use this on when generating
it right?

The image itself.
Also note, that if you use my solution 2, you still might get
problems, as the page that is calling might be cached, and in the
cached page, it refers to the image with the same unique code, and it
will use the cached image again.
Also, if you use solution 2, the image will still stay forever in the
temp folder of the browser(unless the user is cleaning it). If you use
solution 1, the browser will keep it only for this page, and will
remove it afterwards.

Re: [PHP] Is it possible to stop an image from being cached?
Well, this is only one specific image that constantly changes, the rest of
the page is handled regularly.
From what you've said if I go with this
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
That will effect only the one specific image I use this on when generating
it right?

The image itself.
Also note, that if you use my solution 2, you still might get
problems, as the page that is calling might be cached, and in the
cached page, it refers to the image with the same unique code, and it
will use the cached image again.
Also, if you use solution 2, the image will still stay forever in the
temp folder of the browser(unless the user is cleaning it). If you use
solution 1, the browser will keep it only for this page, and will
remove it afterwards.

That's HTTP/1.1 only, but this is what I got from PHP site:

But wouldn't that make every image on the page be uncached and reloaded each
time? Not very efficient if the shell of the site keeps getting loaded if
only 1 or 2 images need to be forced.

Yes, that depends on which way it is used, I wouldn't recommend
loading images from the database that don't get changed...
And you can of course also use an
if-statement/switch-statement/in_array function in your image.php
script, like this:
$img = $_GET['img'];
if($img == "test_a.jpg" || $img == "test_b.jpg") {
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
}
OR:
$img = $_GET['img'];
switch($img) {
case "test_a.jpg":
case "test_b.jpg":
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
}
OR:
$img = $_GET['img'];
$noncached_images = array("test_a.jpg","test_b.jpg");
if(in_array($img,$noncached_images)) {
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
}

My preferred way of doing it, and making sure its reloaded each time is to
do it this way... the U variable pretty much guarantees a random string each
time its loaded.

You will need these functions:

Re: [PHP] Is it possible to save a file with UTF-8 encoding and noBOM using PHP?
Thanks also, Richard! You were right on. Just a note: I just visited the W3C validation service again, and it seems they have recently updated it. It no longer complains if it finds a BOM in your document binary. So it would appear that it's no longer an issue with enough XML parsers to be relevant anymore. Still, it is nice to have a program -like I do- that has that flexibility. -Jon "Richard Lynch" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > On Thu, April 28, 2005 4:14 am, Jon M. said: >> No matter what I do to the strings to encode them in whatever format >> before >> using "fwrite", it ALWAYS seems to end up writing the actual file in >> "iso-8859-1". > > How do you know? > > What are you using to determine the format of the file? > > We are contending that either you are *not* writing UTF-8 data, but are > writing iso-8859-1 data, or the software telling you that it's not UTF-8 > is just plain *wrong* > > fwrite just takes your data and dumps it on the hard drive. > > It doesn't know UTF-8 from U2. > >> Isn't the encoding of the characters in PHP's strings, and the encoding >> of >> the actual binary file on your hard drive, two totally different things? >> Or >> am I just misinformed? > > You are mis-informed. > >> How do you actually control the way the binary file itself is written, >> and >> not just the text that is saved in the file? > > If you are using Windows, then *WINDOWS* is, perhaps, guessing on the > binary format based on the file 'extension' (.txt) and on the contents. > > First, try renaming the file to, err, whatever Windows thinks UTF-8 file > extensions should be...

Re: [PHP] Is it possible to save a file with UTF-8 encoding and noBOMusing PHP?
(Rasmus wrote:) "If you fwrite UTF-8 data to the file, then it is a UTF-8 file." Thanks Rasmus! Honestly, that is REALLY helpful! I was just coming back here to post that I had found that very same answer. But I am glad to hear it confirmed by the experts. Bottom line: I was just being silly/ignorant. I went and downloaded a simple HEX editor and compared the actual binary output of several files that I had created using both PHP, and my favorite text editor (emeditor from emeditor.com). I then realized what probably everyone else here already knew: that (most of the time) the actual binary output from "Windows 1252" and "ISO-8859-1" and "UTF-8 without the byte order mark" -are completely identical! I had the false impression that when a file was saved in UTF-8, that there was an actual binary "marker" that specified this (e.g. binary marker = "This file is saved in UTF-8!") -there simply is no such thing. The only thing that would set "UTF-8" apart -binarilly speaking- is the BOM, and I had stripped that out, making the file exactly the same as plain old "ANSI" (since I didn't have any characters that required "UTF-8", like from other languages etc.). My text editor displays the current character encoding in the status bar, but since there was no way for it to tell whether it was saved with Windows 1252 or UTF-8, it just displayed that the file was encoded "windows default - ISO-8859-1". This is where I got confused. It turned out that my PHP script has been faithfully saving the file in UTF-8 the whole time, and everything was fine. I was just not educated enough about what actually changed when you save a file in UTF-8 but didn't have any characters that differed from ANSI (which in my case, the "change" was nothing, since ALL of the characters in my test document where interchangeable with ANSI). Well, this has been a learning experience! I hope that this post will help some poor ignoramus like myself, sometime in the future! :) And hopefully I am right about what I said above, and not flaunting my ignorance once again -lol Thanks again, to everyone who helped me! You guys really got me on the right track.

How do you know? What are you using to determine the format of the file? We are contending that either you are *not* writing UTF-8 data, but are writing iso-8859-1 data, or the software telling you that it's not UTF-8 is just plain *wrong* fwrite just takes your data and dumps it on the hard drive. It doesn't know UTF-8 from U2. > Isn't the encoding of the characters in PHP's strings, and the encoding of > the actual binary file on your hard drive, two totally different things? > Or > am I just misinformed? You are mis-informed. > How do you actually control the way the binary file itself is written, and > not just the text that is saved in the file? If you are using Windows, then *WINDOWS* is, perhaps, guessing on the binary format based on the file 'extension' (.txt) and on the contents. First, try renaming the file to, err, whatever Windows thinks UTF-8 file extensions should be... ".utf8" ??? Whatever Notepad uses. Next, forget what Windows desktop tells you. It's bull. When you get the data back out of the file, what format is it? PS You may be confusing Windows by writing UTF-8 without the BOM, and so Windows then thinksit's iso-8859-1, because it's no longer a valid UTF-8 file!

If the string originated from your text editor, then your text editor needs to be in UTF-8 mode. If you are importing the data from a file or database then you need to be sure that the data is UTF-8 encoded. If you know that the encoding is instead ISO-8859-1 then you can convert it to UTF-8 with the php function utf_encode. fwrite will then write out the bytes that you presented to it. I guess the same applies in reverse when you read the file back in to the application that will view the text. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Is it possible to save a file with UTF-8 encoding and noBOM using PHP?
Wow, nice to hear from the guy who created PHP! :)
I need to make 2 things clearer though:
1. First I want to know how to make the actual binary file that is written,
to be encoded as UTF-8. This is my PRIMARY question.
2. How to have "fwrite" write the file without the BOM. (to make it more
compatible with certain XML parsers -per the W3C's recommendation).
No matter what I do to the strings to encode them in whatever format before
using "fwrite", it ALWAYS seems to end up writing the actual file in
"iso-8859-1".
Isn't the encoding of the characters in PHP's strings, and the encoding of
the actual binary file on your hard drive, two totally different things? Or
am I just misinformed?
Example: When I open up Windows "Notepad", then I type some stuff into it,
and then I choose "file", "save as", "encoding: UTF-8", then I click "save".
So how do I do this SAME thing using PHP?
Could someone give me a actual code example of how to do that? I'm just
s lost.
How do you actually control the way the binary file itself is written, and
not just the text that is saved in the file?

I wouldn't know a UTF-8 it it walked up and bit me on the ass. :-) But I *do* know that PHP's fwrite is much too low-level to be doing encoding types and whatnot. It just writes whatever you tell it. If you think it's always saving in windows default encoding, perhaps your test is not distinguishing between having no BOM (whatever that is) and having the Windows BOM or whatever makes you think it's Windows format. As far as getting rid of the BOM, assuming you've got your UTF-8 string thingie, and you know where the BOM occurs, you'd just use http://php.net/substr on it, I reckon... -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Strings in PHP are binary-safe and character-encoding neutral. fwrite
doesn't have a clue what it is writing, it just writes what is in memory.
I'd question why you would want to strip the BOM. Any modern system
deals with the byte-order-mark correctly. But you can simply strip it
manually if it is present in the first 2 bytes before your fwrite if you
really need to get rid of it.

If there are only a few types, and you know what those types should look like, it shouldn't be too hard. Maybe. For instance, you could try having ypur application open the putative jpeg with the GIMP, and if the GIMP fails to open it or bombs, then your application rejects the upload. ;-P (If you actually did use the GIMP for this, however, you don't want to call the GIMP directly from PHP/Apache. Not only would it bog your web app down, but it would potentially open your site up to secure attacks against a piece of software that is not known to be secure. What you'd want is something like a cron job to look at the upload directory for new uploads and pass them to a script that would call the GIMP to do the check. That way, if the GIMP dies, there is no open shell connected to an IP port. The cron job would also want to call something to clean up any dead processes left around.) I think there are dedicated jpeg validation libraries floating around. Not sure about MPEG. If it's a simple format, you may be able to write your own parser (regex?) for it, in which case, maybe you only need to check the first 100 or 1000 or so bytes. Checking to make sure a file was _not_ an MS-DOS executable used to be fairly easy. Anyway, whether you parse or let the user tell you (MISE) depends on how careful you need to be (i. e., what your application is going to do with the upload). -- Joel Rees, programmer, Kansai Systems Group Altech Corporation (Alpsgiken), Osaka, Japan http://www.alpsgiken.co.jp -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

As an example, there are many, many, many web hosts out there that allow uploads of files through a form into a web directory. These forms can include CGI scripts. If a hacker uploads a malicious script and you don't have the proper permissions set (i.e. you're running apache as root) your system can be r00ted. Running PHP in safe mode does /a lot/ to help. Making sure any directories you need to make writable (i.e. file storage directories) have .htaccess files or (preferably) it set in the main apache config that they are off limits to web browsers also helps. There are linux virus protection programs available which can be run as a cron job to check files for windows viruses btw. I checked up the price on one and it was like $700 for a server license. :( -Dan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Is it possible to test an uploaded file to check the type?
Thank you for your reply. A little background on what Im doing with file uploading. 1. Im allowing registered users to upload avatars for their own usage. 2. Im allowing image uploading for submitted articles by certain registered users. 3. And Im currently constructing a media gallery, where images, mp3, realaudio, etc can be presented/downloaded/streamed. All 3 points are based on a file upload class that I put together. Of which each section has their own allowed set of mime-types, based on what is supplied via $_FILES['xxx']['type'] An analogy that I have in mind is this. Lets look at the file upload class as the Post Office. They practically allow any package to be delivered to anyone by anyone. They do scrutiny checks on packages. Unfortunately, this one package, has a pipe bomb in it. Its delivered to my mailbox, and poses a threat. Now, is it the fault of the PostOffice for allowing that particular package through? What else can this PostOffice do to tighten things up? So Im at the point, where Im trying to figure out what else I can do to "tighten" scrutiny checks. Concerning infecting the server, if the files are chmodded without the executable bit, shouldn't that be considered *safer* It may seem that mime_content_type() isnt an option. I tried it on a flash file, and it reported it as text/plain. What would really be cool, is a php extension to a virus scanner.

The following is just uninformed opinion, as I haven't sat down and tested any of this, or even thought about it to any great degree. I'd welcome anyone telling me where I'm wrong. I wouldn't want user-created data to end up under the webroot. I'd always be worrying about, say, someone uploading a file that used SSI to sneak the database password file out of the server, or something. And even if I plugged that hole, there might be another, and another... rather than plug individual holes, I'd want to avoid that entire class of problems. The best approach, IMO, is to keep such uploaded files outside the webroot, and call them via a PHP script. Something like /show_resource.php?resourceid=1535 with the resource directory either wy over there, or (my preference) replaced by a database table. The show-resource.php script just has to set the correct mime type header and stream out the contents of the file. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Is it possible to test an uploaded file to check the type?
The upload process, already collects info on file types when you upload. From the manual -> $_FILES['userfile']['type'] The mime type of the file, if the browser provided this information. An example would be "image/gif". So, check $_FILES['userfile']['type'] against a set of allowed file types, and you're set...
