Also it should be an absolute URL otherwise it might break on some (standards
compliant only) browsers:

header("Location: http://www.example.tld/another_page.php");

The reason it works after you put die() after calling your first
header() is because once you send the location header, you can't send
other stuff. Using die() causes script execution to end, which lets the
header work. So put something in there that causes script execution to
end (e.g., exit()).

The proper code (including the properly-formed URL mentioned by others)
is something like:

   if($foo == 'something'){
           header('Location: http://www.example.com/to_another_page.php') ;
           exit();
   }else
   {
        do another thing in here
   }

   header('Location: http://www.example.com/to_previous_page.php');
   exit(); // for good measure

Nope. As others have pointed out, your Location header is improperly
formed.

However, your immediate problem is that, regardless of whether $foo ==
'something', you *always* set the Location header to to_previous_page.php.

So, even if you set it to to_another_page.php previously, you're
overwriting it.

Hope that helps.

While I totally agree with both these pieces of advice, they're
unlikely to be the cause of the problem. YES you should have a space
after the Location: part and YES you should have an absolute URL,
*but* most modern browsers won't care if you haven't - the following
works perfectly on IE6/Opera7/Firefox - no matter how malformed it
looks:

Header("Location:page2.php");

Chris provided the solution to the original problem in his reply, but
I just wanted to bring this up. The OP should of course modify his
header statements, but its unlikely to resolve his problem on its own.

In PHP's logic however, it doesn't stop :)

(Unless you tell it to by either using an exit() call or just making
the header function the last line of your script).

No.... it still doesnt work ... I have to put die() or exit() after
calling the header(); .... and whether I put space and not using space
.. the result still same .. ( I am get used not to use space for
almost 1 year .. and suddenly I just know that I should put space :) )

In my logic, after we call header('location: foo.php'); the php
processor should terminated and open the page foo.php instead ...

You might still want to do some processing after the redirect header.

You're joking, right? Your second "header" statement is outside the if/else loop, so it's
executed every time, obviously. This in turn means that your script will always redirect to
"previous_page.php", unless, of course, you kill it before it gets to the second "header"
statement. Suggestion: read up on control structures (chapter 11 in the PHP manual).

Another thing you need to know, header checks if the same header was
output before, if yes, it is owerwriten by the second one. So if you write:

header('Location: foo.php');
header('Location: bar.php');

only one header is output.

You can pass false as the second parameter to header (replace
parameter), in this case both headers are output.

This might make sense to you, but only because you're thinking of header()
as a redirect function. First, you must realize that it is not. It is a
function that sets an HTTP header.

If you've worked with headers much before, you may have run into an error
that says something like this:

Warning: Cannot add header information - headers already sent by (output
started at ...) in ... on line ...

To avoid this error, people must either set the headers they want prior to
any output (often by placing calls to header() at the top), or they use
output buffering.

So, consider that you use header() at the top of your script. Now, you
want to generate an image, so your script begins like this:

<?
header('Content-Type: image/png');

The rest of the script generates the image. Wouldn't you be frustrated if
PHP decided to stop at the header() call? That would certainly frustrate
me.

Now, PHP could identify when the header() call is going to change the
status code of the response. Perhaps, if the response is going to be a
300-level response, PHP should exit afterward. But, why make such a
dangerous assumption when the developer can exit if he/she wants?

It would also break things like this:

<?
header('Location: http://default.org/');

if ($foo)
{
header('Location: http://foo.org/');
}
elseif ($bar)
{
header('Location: http://bar.org/');
}
?>

While this may not be eloquent, hopefully it is clear that the author
intends for the user to only get redirected to http://default.org/ if both
$foo and $bar are false. If PHP exited immediately after the first line,
this script would not behave as the developer intendend. PHP's assumption
would be wrong.

Hope that helps.

attached mail follows:

This is not a bug. Here you expect that the script should end executing
after the statement:header('Location:to_another_page.php') if the "if"
statement is true. But it won't and it proceeds to the next statement;
the next header statement:header('Location:to_previous_page.php');

An "exit" statement after the first header will solve the problem. With
most browsers, if multiple redirect headers are received, the last
instruction is followed. I'm not sure what the RFC says about this.

H'mmm -- one other thought in addition to all the other good pointers: is short_open_tag On or Off? Because if it's off, none of those <?= snippets will fire anyway.

A few questions:

  a) What's the exact version of PHP?
  b) Please post the smallest possible form that creates this
     problem.
  c) And how are you attempting to access these form values?

If you're interested in some working examples and related
information, have a look at the following manual page:

Thanks for the suggestions, first of all. I tried that exact code from the
code you included and I cut and pasted the "Simple HTML Form", and below
that I pasted the "Accessing Data..." php code. When I go to the page, all
it does after I hit the submit button with data in the fields, is say "no
input file specified". But when I run it through the url giving the input
names with values, it returns them. I tried getting it working with like ten
people so far, and no one's been able to figure out... I am running PHP
4.3.4, btw.

Hi,
I am new to manipulating JPGs using PHP. But i managed to create an
application that displays an JPG image in the browser (see below).

I have boiled the code down to the most nesesary.

My problem is that when i load the file "c:\file.jpg" directly in the
IE browser (using <IMG SRC='c:\file.jpg'>), and then get properties on the
image by
right clicking in the browser. the size is the same as it is on the HD
(83Kb).

However when i use the PHP code and get properties on the image by
right clicking in the browser. the image size is 264Kb.

How come the picture is bigger when loaded trough PHP as it is when
loaded trough the browser directly ?

best regards

Because you are sending it at 100% quality which is no compression, try
backing it off to 30%. Probably the original was not at 100% quality
anyway.

Programming bar code reader from PHP?

It truly largely depends on the brand of bar code reader, and even then,
the model.

For example, I programed for an Intermec Antares 24xx series handheld
(that model is made for standalone/independant operation). For your
operations, this isn't very good model (not counting expensive).

Bar code readers work in serveral possible ways...
1. RF/networked (more advanced models)
2. serial port, where the reader streams what has been read in
3. keyboard port, and when it reads a bar code, it sends the proper
characters back to the computer.

I'd recommend baseing your design on models where the computer can have a
driver that does direct translation and the bar code reader acts like a
keyboard. Then you just have to make a standard webapp, and your text
input fields are populated by the values that are read in from the bar
codes.

I don't have any links off the top of my head to help you get a better
foundation in this, but google must have plenty ;)
To visit a company that works in bar code equipement, find Intermec's
website.

You use a thing called a wedge. It plugs into your keyboard port on your
computer. Then you plug in the keyboard and the scanner into the wedge. You
must program your PHP to not look for "submit" buttons. You also need a
browser that will submit a page when you press enter in a field.

You can also get scanners with USB connections that work like keyboards.

We've written a Warehouse Management System using these devices and a barcode
printer. It's written in PHP and uses MySQL database. We use walkabout
computers connected to the forklifts and cherrypickers. It's been working
great now for almost a year now.

Hi folks,
I'm using usual md5(microtime()); to create IDs, but now I've encountered a

Is there any other way than checking with all previous IDs? Or some MySQL

If the data is so important - why are you restricting it to a 6 digit
key? You should ideally use the uniqid() function perhaps with a
combined lcg entropy at the end. That will give you a 13 character
long unique id - or md5 it for a 32 character one (see the manual for
examples).

A> Is there any other way than checking with all previous IDs? Or some MySQL
A> function to do this for me?

For something so important I would use (a) a longer unique ID and (b)
I'd still run a SQL check to see if the ID has been already used or
not. A simple MySQL count will bring that result back very quickly.

MySQL (or another SQL database) is the answer. You can check for an
existing OR use it's auto_increment or whatever else you like.

Create a field to track all this stuff. There is no other way to
guarantee that an ID is unique than to check it against existing.
"Random" functions yield random results, so each time, there is ALWAYS
a chance of a number being repeated. Microtime works pretty well, but
there is STILL a chance two people could have a transaction at the same
time. Yes, the odds can be insanely, insanely small for various
functions (i.e. MD5) but as you shorten the length of your number, the
odds get higher.

And yes, it's important to realize that a 6 digit unique identifier is
limited to 1 million possible combinations, not nearly enough for most
banks.

I might suggest you do some more PHP learning before you go and develop
an online bank application - this stuff is pretty fundamental
programming and database concepts. If your overall skill level isn't
very high, you're likely to make mistakes, and either have errors,
problems in functionality, or, worse, security problems.

Well, that looks very suspicious, and probably not for the reasons you're
thinking.

I can explain why you get that result, but it means that either (a) there's
a bug in gmmktime(), or (b) the documentation for gmmktime() is wrong (or,
at least, misleading). So, let's take it step-by-step:

1. gmmktime(), according to the manual, should use the "current
corresponding GMT value" for it's omitted arguments.
2. In my book, at 23:52:08 EST that means it should be using 04:52:08 GMT on
the following day (we'll discuss this later, since, whilst giving a
different result, it still wouldn't produce what you're expecting!).
3. However, let's guess that gmmktime() is actually using the *local* time
value of 23:52:08, but treating it as if it were GMT.
4. In which case, you'll get a timestamp for 23:52:08 GMT.
5. Because timestamps are absolute (not adjusted for timezone), this is also
the timestamp for 18:52:08 EST.
6. 18:52:08 is what you're getting printed.
7. QED.

This behaviour is *not* what the manual says should happen, and in my
opinion is counter-intuitive. However, if gmmktime() were to behave as the
manual, at least how I read it, suggests, this is what would happen:

1. gmmktime() would calculate a timestamp for 04:52:08 GMT (next day).
2. Because timestamps are absolute, this is also the timestamp for 23:52:08
EST.
3. So strftime() still outputs 23:52:08.

Ergo, this is not the way to produce an adjusted time. One way to do what
you're looking for is to feed the same timestamp to date('%H:%i:%s') and
gmdate('%H:%i:%s). If you want something you can feed to strftime() for the
GMT date, you need to acquire your timezone's offset from GMT in seconds
(e.g. with date('Z');) and subtract that from the timestamp.

Well, then you would get the tradeoff that you have to test whether the value supplied is a simple scalar (because only one option was checked) or an array, before you could work with it. IIRC, that's what you do in perl and ASP. PHP takes the attitude that the code should be as simple as possible, and therefore it's the FORM's responsibility to indicate where POSTed values should be treated as arrays.

Personally, I think I could live with having to write code such as $checkboxes = (array)$checkboxes, but this is a choice the PHP implementers have taken, and I don't see it changing in the foreseeable future.

Cheers!

It's possible.

The easiest way to do this is:

# On the webserver, you just need Apache, with a redirection setup.
So if a user entered http://webserver/genome-processing/ then it'll be redirected to http://application-server/genome-processing/
Example (put these in httpd.conf):

================
<IfModule mod_proxy.c>
ProxyPass /genome-processing/ http://application-server/genome-processing/
ProxyPassReverse /genome-processing/ http://application-server/genome-processing/
</IfModule>
================

# On the application server, you'll need Apache+PHP and that C program.
genome-processing/index.php in this box should process all user input, and then execute the C program with system() function:
http://uk.php.net/manual/en/function.system.php

# Ensure that the output from the C program can be easily parsed in PHP, or better yet, already HTML-tagged properly so you don't need to process it any further in your PHP script - just printf() the whole of its output straightaway.

There are other ways to do this, but as I said I think this is the easiest way.
CMIIW of course.

If you have changed *nothing* at all that could influence the outcome
of this script then I would suggest you just upload your original
files again and over-write what is on the server. It's possible they
have been corrupted somehow.

Failing that it's time to start debugging - if you use a decent IDE
like Zend then start slapping breakpoints and watches all over the
place. If you don't, start echo'ing out values left right and centre
as you enter key parts of your script.

On page two you'll have $_POST['image'] as an array containing elements 'one', 'two'
and 'three' ($_POST['image']['one'] etc). This is *pretty* basic, so I'm guessing you'll
have to learn some more PHP before you can actually do anything with this array.

If you have some experience with other programming languages, you'll probably find
that the first few chapters of the official PHP manual (http://www.php.net/manual/en/ )
will get you up and running in no time flat.

Good luck,

I would not use DATETIME column type for Total as it is dependable on
the number of days in the month. Use INT and store the number of seconds
instead. Then you can update the column using:

UPDATE oras SET Total = SELECT UNIX_TIMESTAMP(field1) -
UNIX_TIMESTAMP(field2) [WHERE where_condition]

instead. Then you can update the column using:

UPDATE oras SET Total = SELECT UNIX_TIMESTAMP(TimeIn) -
UNIX_TIMESTAMP(TimeOut) [WHERE where_condition]

Hello,

I'm working with a DB SQL Server. This DB has a table with Japanese
characters.
When I read a field (with Japanese characters) with function
mssql_fetch_array(), always it return characters '?'.

If I put 'print("(Japanese characters)");', these Japanese characters are
shown correctly.

My PHP file has follow code to work with Japanese characters:

mb_internal_encoding("EUC-JP");
mb_http_output("EUC-JP");
mb_http_input("EUC-JP");
mb_language("Japanese");

My question: How can I show correctly the Japanese characters from a SQL
Server DataBase?

Thanks very much!
Juan Torres.

Hi,

I believe it's hiccuping at this:

<msxsl:script language="JScript" implements-prefix="user">
<![CDATA[

   function EscapeURL(selection) {
     if (selection(0) == null)
       return "";
     else if (selection(0).hasChildNodes())
       return escape(selection(0).childNodes(0).nodeTypedValue);
     else
       return escape(selection(0).nodeTypedValue);
   }

]]>
</msxsl:script>

not being an expert on the MS XML api i not in a position to help you further. you should send this to an XSLT list.

Can PHP interface with other programs through DDE?

hi,
I am having problems with recode extension for php 4.3.4.
this is the configure options :
'./configure' '--prefix=/usr/local/linkbynet/php'
'--with-gd=/usr/local/linkbynet/gd2' '--enable-gd-native-ttf'
'--with-freetype-dir=/usr/local/linkbynet/freetype2'
'--with-jpeg-dir=/usr/local/linkbynet/jpeg6b/'
'--with-pdflib=/usr/local/linkbynet/pdflib'
'--with-png-dir=/usr/local/linkbynet/libpng'
'--with-dom=/usr/local/linkbynet/libxml2'
'--with-zlib=/usr/local/linkbynet/zlib'
'--with-mysql=/usr/local/linkbynet/mysql'
'--with-apxs=/usr/local/linkbynet/apache/bin/apxs' '--with-imap'
'--with-recode' '--enable-ftp' '--enable-bcmath'

this sample code gives me a segmentation fault :
<?
    $text =
  "062806310648062D002006270644063306480642002006270630062"
."70631062C0639062A002006460643064506440020064A062706380"
."628064A00200627064406270645062706310627062A00200645064
."6002006280646062A0020062706440631064A06270636";
    $text = pack("H*", $text);
    $text = recode("ucs2..utf-8", $text);
    echo "'$text'\n";
?>

$text is a ucs2 text in hexadecimal. so I just decode it with pack() and
then convert it into utf-8.
if I remove 4 digits at the end of the hexa or add 4 digits (0623 for
example) at the end, it works.

what can I do about this?
thanks for your help.

Jeremy --

You have started a new thread by taking an existing message and replying
to it while merely changing the Subject: line.

That is bad, because it breaks threading. Whenever you reply to a
message, your mail client generates a "References:" header that tells all
recipients to which posting(s) your posting refers. A mail client uses
this information to build a "thread tree" of the postings so that it is
easy to see just how they relate to each other.

With your posting style you successfully torpedoed this useful feature;
your posting shows up within an existing thread even though it is
completely unrelated.

Always do a fresh post when you want to start a new thread. That means
that you do not select any sort of "Reply" when you start your message.
You can save the list address in your address book (or equivalent) for
convenience.

Hi!

%
% What does the ampersand do in the bottom example code, they both work.
%
% $n1 = $num1 -> function();
% $n1 = & $num1 -> function();

1) Search the manual.

2) Assigning by reference, as compared to the default assigning by value,
means that the variable on the left of the '=' now points to the very
same little chunk of memory as the variable on the right. This is
different from the usual assignment in that when you change the left var
you change the value for the right var, too.

  $a = 1 ;
  $b = $a ;
  $c = &$a ;
  $b++ ; $c-- ;
  print "a = $a ; b = $b ; c = $c ;\n" ;
  // a = 0 ; b = 2 ; c = 0

3) You can't, as far as I know, assign-by-reference a function, so your
code should generate a parse error.

I saw the article at http://us2.php.net/manual/en/function.fileatime.php and
gave it a shot with the timestamp for the file but it doesn't work correctly
because it only returned the current timestamp (as it is from our watch or
clock) but not the one from the file...

I had verify that the file is correct and that the date() is working
correctly and that the timeatime() is working correctly if they are tested
independantly, so it is just putting them all three together cause them not
to work right...

--snip--
$current_filename = "test.pdf";
echo (date('F j, Y, h:i a', (fileatime($current_filename))));
--snip--

What did I do wrong??
