I am trying to loop through some database results to build an array similar

And the problem that I am having is that array_push does not want to take
keys when I am using it.

Mike,
the solution is quite simple, and is already buried in some of the
responses until now.
Modifying your sample code, this will work and generate your expected results:
$transactions=Array();
While($row=mysql_fetch_array($res) {
// array_push($transactions,$row[dealercode]=Array());
$transactions[$row['dealercode']] = Array();
$another_query=mysql_query(do another query here);
while($morerows=mysql_fetch_array($another_query)) {
// array_push($transactions[$row[dealercode],
//$morerows[country]=$morerows[amount];
$transactions[$row['dealercount']][$morerows['country']]
= $morerows['amount'];
}
}
Hope this helps,

Re: [PHP] disable notice errors

[snip]
how to disable notice error output
i have set error_reporting = 2039 (in PHP.ini);
but it doesnt work.i still get notice :Undefined index..
[snip]
as a third method, you can explicitly disable warnings and errors for a
single command using the '@' modifier.
This is widely unknown but a very handy feature: having excessive
error_reporting turned on [error_reporting(E_ALL)] helps a lot in spotting
down possible problems in your code, but again there are numerous locations
where e.g. array keys might be there, or not. You could either use
array_key_exists(), or the @ modifier to suppress the warning.
Example:
// this will raise a warning
$test = $array['nonexisting_key'];
// this avoids array access if the key is not set,
// OTOH the receiving variable might be undefined
if (array_key_exists('nonexisting_key', $array))
$test = $array['nonexisting_key'];
// this is a simple, elegant, and even self-documenting solution
$test = @$array['nonexisting_key'];

I've run into people wanting to do this before (with Excel spreadsheets, no less). And in fact, it's probably the most convenient way of doing things, as long as they're warned about certain dangers (overwrites from competing unsynced database files).

Re: [PHP] identify not only browser, but even browser windows with session
At 10:58 24.06.2003, dorgon said: [snip] can cookies be stored for single browser instances (windows)? does the browser send some information that could be uses? [snip] Short answer - no, and no. Cookies are stored browser-wide, and if the user presses Ctrl+N (or else) to open a new window you would never detect it. Even using some sophisticated techniques like session access counters, session serial numbers, etc, are not guaranteed to work since the browser may have cached the page contents and simply _locally_ copied it to the new window, not issuing a new request. However you may use a serial number in session data that is incremented with each request. Incorporate this number in any form or session-based link to have the browser transmit it back to you. Then compare if the serial number matches the expected vale; if not it's a reload and you can proceed as seems fit. However you don't have a chance to recognize if the reload comes from simply a page reload, or from a window clone. BTW - this is the reason I have switched off session cookies at my servers. Having the SID available allows to run more than one session from a single browser instance. HTH, -- O Ernest E.

pVisit a href=http://memigo.com;memigi/a to learn about current

What I want is to run a preg_replace to get the following:
Visit My personal site (http://jaxn.org) to learn more about me.
Visit memigo (http://memigo.com) to learn about current events.
stripping the HTML is easy, but before I do I want to convert the links.
The loop I posted does exactly that (using square brackets as to your
initial requirements). The 3rd parameter of preg_match ($aresult) will be
an array that holds the grouped expressions from the regex:
[0] - whole string
[1] - pre-match (all before a href)
[2] - the URL part of the link
[3] - the linked text
[4] - postmatch (all after the closing /a).
Within the loop I use this array to modify the HTML code to read
(pre-match)#linked-text# [#url#]...
which is what you want, after all.

The problem is that some links may have additional modifiers and onthers

Hello, I am new to PHP and would greatly appreciate any help.
I am building a webpage for my sister's sorority- http://olemissddd.com. I
have built a page that allows them to update the officers each year-
http://hedges.org/ddd/olemiss/updateofficers.php and then view those
officers- http://hedges.org/ddd/olemiss/officers.php .
However, what I want to be able to do that I can't figure out is for when
they leave one of the fields blank it doesn't change anything. As it is
now, when they change one of the fields and leave the others blank it will
overwrite the names it had for them with blank spaces. I want to be able to
do this so for example if they mistype someone's name, etc. So somehow I
need to be able to tell it that when the user leaves the field blank, not to
change that field in MySQL.

Try something like
if (!empty($_REQUEST['fieldname']))

The problem is your notation. If you had written
if ($mo == 6 and $dy 1 and $dy 9) { $wd = 8; }
if ($mo == 6 and $dy 8) { $wd = 9; }
your logic would still look a bit clumsy but work as you intend.
Why? Prefixing a number with a zero makes the intepreter believe you're
using octal numbers. Oczal numbers range from 00 to 07, the decimal number
8 would be 010 in octal notation. Your code, translated in decimal for
better understanding, is seen by the compiler as
if ($mo == 6 and $dy 1 and $dy 2) { $wd = 8; }
if ($mo == 6 and $dy 0) { $wd = 9; }
(08 = decimal 0, 09 = decimal 1). In this case your last statement will
trigger for _any_ day in June.

This depends on the contents of your library. If you have it included
within the function, all variables and data structures created within the
included file are within the function's scope. If included outside, they're
on a global scope - you would need to use either the $GLOBAL superglobal
array, or to declare them being global within the function that uses them.

You've disabled cookies, either in your browser, or in php.ini completely

This email is long I apologize for that. It is my code and then what

[snip]
The compare callback is expected to return anything 0 if the first value
is less than the second (should sort _before_), 0 if they are identical,
and 0 if the first value is greater than the second (should sort _after_).
Taking this, your comparison callback directs PHP this way:
if ($A[STARTDATE] $B[STARTDATE]) { return 4; }
if $A starts before $B, $A is greater (after $B).
if both start dates are equal, or $B starts before $A, continue.
else if ($A[STARTTIME] $B[STARTTIME]) { return 3; }
if $A starts before $B, $A is greater (after $B).
if both start times are equal, or $B starts before $A, continue.
else if ($A[ENDDATE] $B[ENDDATE]) { return 2; }
if $A ends after $B, $A is greater (after $B).
if both end dates are equal, or $A ends before $B, continue.
else if ($A[ENDTIME] $B[ENDTIME]) { return 1; }
if $A ends after $B, $A is greater (after $B).
if both end times are equal, or $A ends before $B, continue.
else if ($A[STARTDATE] $B[STARTDATE]) { return -4; }
if $A starts after $B, $A is less (before $B).
if both start dates are equal, continue.
else if ($A[STARTIME] $B[STARTTIME]) { return -3; }
if $A starts after $B, $A is less (before $B).
if both start times are equal, continue.
else if ($A[ENDDATE] $B[ENDDATE]) { return -2; }
if $A ends before $B, $A is less (before $B).
if both end dates are equal, continue.
else if ($A[ENDTIME] $B[ENDTIME]) { return -1; }
if $A ends before $B, $A is less (before $B).
if both end times are equal, continue.
else { return 0; }
they are identical.
I believe you see where the problem is. You may express your comparison in
a shorter and possibly clearer form like this (not tested but looks as if
it should work):
if ($A['STARTDATE'] $B['STARTDATE']) return -1; // a starts before B
elseif ($A['STARTDATE'] == $B['STARTDATE']) { // starts at the
same day
if ($A['STARTTIME'] $B['STARTTIME']) return -1; // a starts before B
elseif ($A['STARTTIME'] == $B['STARTTIME']) { // same start day
and time
// here both courses start at the same day/time,
// so we need to sort them by enddate/time
if ($A['ENDDATE'] $B['ENDDATE']) return -1; // a ends before B
elseif ($A['ENDDATE'] == $B['ENDDATE']) { // ends at the
same day
if ($A['ENDTIME'] $B['ENDTIME']) return -1; // a ends before B
elseif ($A['ENDTIME'] == $B['ENDTIME']) { // same end day
and time
// identical
return 0;
}
}
}
}
// we've tested all possibilities for A being less or equal to B
// so there's only one more choice left - A is greater :)
return 1;

After this construct
$message_new = $phone is not a valid phone number.
Please try again.;

you have a closing curly brace that doesn't belong here. Remove it.
Now your code should run without errors (syntax errors, that is)
Hint: You should make a habit of using a more clear indentation (if your
code is actually as it is in the mail). A single column indentation is not
enough to make block levels clear at the first sight. You better use 4 or 8
columns indentation width.

RE: [PHP] Passing data between the web to an Intranet
Here's some ideas how I'd go for something like that. I'd have some PHP on the externally hosted website, and some PHP on the Intranet/CRM-DB server. At 08:39 27.03.2003, Steve Jackson said: [snip] gathering tool. Basically what I'll need to set-up is some sort of system which: 1) Validates user input from the web (php) Should be done on the external website box. 2) Sends the information to the external website DB for future customer login authentication (php mysqlupdate/insert) Same thing here - PHP on the external box. 3) Sends the information to our internal website DB (Intranet server) (email or replication?) A PHP form residing on the internal box to receive POSTed data from the external box. The external box would use cURL to post aony content that needs to go internal. 4) Flags our people here when a new prospect arrives (phpemail) 5) Full front end system for the prospect details etc (Intranet server). (php/mysql) Both internally, PHP intranet style. Using this approach you have full control over what goes into the internal DB; much better for this task IMHO than replicating a complete DB. Of course you need to make sure that only the external webbox can post to the Intranet server, the level of authorization depends on your security considerations and the network layout. If the Intranet host only has a private IP (192.168.*, or 10.*) but can be reached by the external box via secondary interface this aint really an issue since it can't be reached from the outside. If the Intranet box _could_ be reached from the outside I'd recommend to run the receiving form on an SSL interface, the external box using a client certificate to authenticate itself. AFAIK this can be done with cURL. HTH, -- O Ernest E.

2. Check out serialize()
http://www.php.net/manual/en/function.serialize.php

3. However, this creates a URL which isn't particularly URL friendly (not

4. based on your array's size, I'd just implode() it, and then explode() it
back out on the new site:

In both cases (serialize, and implode) you should urlencode the results:
window.open('view.php?arr=?=urlencode(serialize($arr))?','windo...
window.open('view.php?arr=?=urlencode(implode('-',$arr))?','windo...
Should make for a valid URL then. However don't forget that passing
application data via URL could pose a security risk to your application,
depending on what the data actually represents, and how it is worked on.
Consider also that URLs have some size limit (don't have the number at hand).

Re: [PHP] Finding out which file is retrieved over HTTP
At 13:08 25.03.2003, Jens Lehmann spoke out and said:
[snip]
A thing which seemed a bit confusing to me is that if I open a
non-existing website (fopen('http://www.amazon.de/nonsensestuff')) I
always get an error message Success. It's the same thing if I use
file(). The manual explains that fopen() returns false if the website
could not be opened, that's why I don't know why this error message
appears? Besides this Success-message is surely a very bad error
message. I use PHP 4.2.3.
[snip]
If the website doesn't exist, but the web SERVER does, it will return
something, usually a 404-message. fopen() doesn't check for HTTP result
codes, it just opens the stream and retuirns whatever gets sent (with the
single exception of omitting the headers, but without looking).
So in fact an fopen() to a non-existing page will be seen as successful by
fopen(). This is by design and afaik documented somewhere.
To actually check on the HTTP status codes you need to run your own, either
using cURL, or by doing your own stuff using fsockopen().

I tried using fsockopen(), but still experience a problem, I want to use
the following script to retrieve both, the headers and the actual file:
You need to transmit the Host: header so the web server has a chance to
know which virtual host you want to reach. Ideally you would also tell the
server what type of content you can handle (see below). Also note that the
correct line ending for MIME headers is always CRLF (\r\n):
$hostname = 'www.example.com';
$file = '/index.php';
$ip = gethostbyname($hostname);
$fp = fsockopen($ip, 80, $errno, $errstr);
if ($fp)
{
fputs( $fp, GET .$file. HTTP/1.0\r\n .
Host: $hostname\r\n .
Accept: text/html\r\n .
Accept: text/plain\r\n\r\n );
$src = '';
while (!feof ($fp))
$src .= fgets($fp, 4096);
fclose ($fp);
}
This will get you the whole page, including all headers.

This is if $phone is anything else than a single digit. You need to add

Re: [PHP] array insert help

[snip]
My problem is that I'm not sure how to set up the array for the fields and
how to take the input fields and insert them. Do I need a multidimensional
array for this?
ie.
input type=text name=address[address][]
input type=text name=address[city][]
How would I decode that to create an insert statement??
[snip]
I believe your example would work. However since you have a definite number
of adresses you could add the index directly, as here:
bHome Address:/bbr /
input type=text name=address[address][0]
input type=text name=address[city][0]
bWork Address:/bbr /
input type=text name=address[address][1]
input type=text name=address[city][1]
When the form is received you will have an array for adress that looks like
this:
$_REQUEST['address'] = array(
'address' = array(0 = 'home address', 1 = 'work address'),
'city' = array(0 = 'home city', 1 = 'work city'));
To insert the home address you'd create an SQL statement like this:
for($i = 0; $i = $number_of_addresses; ++$i) {
$sql = insert into address(adress, city) values ( .
{$_REQUEST['address']['address'][$i]}, .
{$_REQUEST['address']['city'][$i]});
// more code
}
Hope this helps,

What would be the value then?
If I get you correctly, you would treat an array that comes like
[0] = entry 0
[1] = entry 1
[2] = entry 2
as
[entry 0] = ??
[entry 1] = ??
[entry 2] = ??
What happens when there are duplicate values in the source array? You will
loose entries on duplicate values.
If I got you right here have a look at array_flip()
(http://www.php.net/manual/en/function.array-flip.php) to exchange array sides.
You can't tell with absolute certainty if an array is enumerated, or built
as associative array. Take this example:
$a = array('one','two','three');
$b = array(); $b[0] = 'one'; $b[1] = 'two'; $b[2] = 'three';
$c = array(0 = 'one', 1 = 'two', 2 = 'three');
Which one would you believe is enumerated, and which one is associative?
What you can do is walk the array keys and check if there is at least a
single non-numeric key. If you found one the array is associative. If you
found none it may be likely that the array is enumerated, but you can't be
sure in a general way, except your application is designed in a way that
uses always non-numeric keys for associative arrays.

they'd all be enumerated, except perhaps $c -- but i've grown :) and now
understand that $c winds up being an enumerated array.. or is it?
Well, all these 3 arrays are _exactly_ the same. If you print_r() them
you'd see
Array {
0 = one
1 = two
2 = three
}
The key to this issue seems to be understanding that it makes no difference
how the array keys are constructed... an array is an association of key to
value, being a hash always if you want to see it that way.
in my code
$q = mysql_query ( SELECT production_id, title FROM productions ORDER
BY title; );
$this-all_productions[] = ;
while ( $row = mysql_fetch_array( $q ) ) {
$this-all_productions[$row[production_id]] = $row[title];
}
the array is kept in order when i foreach the array - wouldn't they sort
themselves into 0,1,2,3,4,5,etc if my while loop was populating an
enumerated array? or are all arrays in php actually a keyed hash?
You're chosing your own keys here - so this makes a perfect associative
array, even if the keys ($row['production_id']) would be a sequenced
number. If you would just add the titles up ($this-all_productions[] =
$row['title']), PHP would choose an index key for you - the most general
thing it can do is to enumerate it. Basically what it does is
array[count(array)] = new_element
So much for the theory - what are you really trying to achieve? Maybe
there's something you can redesign so you're not relying on the fact if an
array is enumerated or not.

Re: [PHP] internally stored binary image

[snip]
In order to distribute a single script I would like to store a small
image internally. Is this at all possible with PHP? How would I go about
it? Please feel free to rtfm me to the relevant sections.
[snip]
You could make some script to retrieve the hex values of the image byte by
byte, then create a source file like
$imgdata = '\xff\x19\x00\x12 etc...;
Then when you're about to send the image simply transmit the correct
header() and echo out the data.
This little sample works just perfectly:
// use one of your files here, of course...
$file = 'images/dart.gif';
$hf = fopen($file, 'r') or die(Can't open $file for reading);
$bin = fread($hf, filesize($file));
fclose($hf);
$asc = '$img_data = ';
for ($i = 0, $len = strlen($bin); $i $len; ++$i) {
if ($i !($i % 16))
$asc .= \ .\n\t\;
$asc .= '\\x' . bin2hex(substr($bin, $i, 1));
}
$asc .= ';';
// $asc now contains the hex-coded binary file.
// Example (a real gif - try it)
$img_data =
\x47\x49\x46\x38\x39\x61\x20\x00\x20\x00\xa2\xff\x00\x00\x00\x00 .

Re: [PHP] Forced Download Using header()
At 11:16 18.03.2003, Kevin Kaiser said:
[snip]
I have a simple php download script that streams a
non-web-accessible file
to the browser using this generally accepted method:
header(Expires: 0);
header(Cache-Control: private);
header(Content-Type: application/save);
header(Content-Length: .filesize($total) );
header(Content-Disposition: attachment; filename=.$file_Path);
header(Content-Transfer-Encoding: binary);
$fh = fopen($total, rb);
fpassthru($fh);
While it works, this is fairly useless in my situation where files
range
from 5mb to over 100mb, because due to fpassthru() or readfile() or whatever
method used to stream the data to the recipient, the 'save as'/'open' dialog
doesn't open until the entire file has been downloaded. This is very
impractical since the user has no clue how much has been downloaded / how
much longer is left, not to mention that on very large files (~75mb) apache
will actually freeze up and become unresponsive to all users (sending cpu
usage to 100%) for nearly 10 minutes or more, assumedly because it is still
reading the file (regardless of whether the 'stop' button has been clicked
or not).
With the last 2 lines commented out (fopen() and fpassthru()), the
save-as
dialog opens instantly.. is there any way fopen/fpassthru() could be delayed
until after the user chooses to open or save the file ? How would you guys
go about handling large file downloads while keeping the files themselves
non-web-accessible (aka not a direct link/redirector)?
[snip]
Disclaimer - this is just an idea, I've never dealt with downloading that
big files.
If apache freezes because the file it's reading is too big to be handled
I'd suggest to try a chunked approach, not using fpassthrough or a single
file read. The reason is that for every system I/O the operating systems
get a chance to switch process context, and to allow cooperative multitasking.
Would go something like that:
define('CHUNKSIZE', 8192);
$fp = fopen($file, 'r') or die (Cannot open $file);
header(Expires: 0);
header(Cache-Control: private);
header(Content-Type: application/save);
header(Content-Length: .filesize($total) );
header(Content-Disposition: attachment; filename=.$file_Path);
header(Content-Transfer-Encoding: binary);
// --
while ($buffer = fread($fp, CHUNKSIZE)) {
echo $buffer;
}
fclose($fp);
You may need to experiment with the size of the chunks to keep up an
acceptable transfer rate. If you still encounter big holdups for other
processes you might consider using usleep() every 10th chunk or so, but use
your calculator to check how that would extend the overall transmission
time. For example, for a 100MB file, going to usleep for 50 msec after each
9kb chunk would mean that your process will sleep for 1.82 hours (!!) until
the file is delivered...

[snip]
Is it just as quick to do:
if($r == 0) {
} else if($r != 0) {
}
than to do:
if($r == 0) {
} else {
}
The reason I like the former method is because, in a large IF-ELSE block,
it's clear what belongs to what IF and what's going on. But does this make
it lag? And, if so, is it really all that noticeable?
[snip]
Noticeable? Probably not, except you're timing loops of a million or more
cycles... but it's clear that the second method needs more time (in terms
of cpu cycles) than the first one.
In Intel speak, what would a compiler translate these code examples to?
if (a == b) {} else {}
mov eax, {a}
cmp eax, {b}
jnz L01
; the true block goes here
jmp L02
L01:
; the false (else) block goes here
L02:
As you can see there's two memory operations and one comparison.
Your second example:
if (a == b) {} else if (a != b) {}
mov eax, {a}
cmp eax, {b}
jnz L01
; the true block goes here
jmp L02
L01:
mov eax, {a}
cmp eax, {b}
jz L02
; the second block goes here
L02:
There's four memory operations, and two comparisons.
As another poster already pointed out, there's also a slight difference
comparing something to zero, or to false:
if (a == 0)
mov eax, {a}
cmp eax, 0
jnz L01
if (!a)
mov eax, {a}
or eax, eax
jnz L01
The latter version consumes approx. half of the time (in cpu cycles)
compared to the first one.
Modern compilers will leverage the need for a to deal with these efforts.
The multi-pass optimizers usually detect situations like these and would
use the if (!a) {} else {} construct, without regard what your original
input is.
However, PHP is _not_ a compiler, it's an interpreter. It compiles code
at runtime and has not the ability to perform exhaustive optimizations
which would cost far more time than can be gained within a single
execution. Additionally there's the time needed to parse the input stream
(tokenize, add to symbol table, execute token and expression parser, etc
etc). With interpreting languages the differences will rocket skyhigh
compared to compiled executables.
Well, it's still to be measured in nanoseconds for a single instance,
thanks to modern processor power...

You need to create a number out of the dotted IP string to use them in
valid = and = comparisons. This is a valid procedure, since the IP
basically _IS_ a number, it's just written in the dotted notation to aid us
miserable human beings.
$abytes = explode('.', $ip); // explode the IP string
$ip = 0;
foreach ($abytes as $byte) $ip = ($ip 8) + $byte;
This will give you the valid numeric equivalent of the IP address.

Re: [PHP] Re Sessionid

Is the value returned by session_id (), called after session_star() always a
unique string?
The results of several trials gave me:

26dda220f9d64de593ce2f2de6b4bb6e
i.e. every time i started a new session I got a unique string, while the
string remained the sme within the same session.
[snip]
That's exactly how it should be. The session ID is the unique key to the
session private data, and is passed between client and server either via
cookie, or via request parameter, whatever is necessary (PHP can determine
this automatically).
The key is supposed to be unique on a single server. It is derived by
calculating a random value, starting with the current systems sec/usec, and
a random number. If an external entropy source is available the resulting
ID is further randomized using this entropy. Finally it is converted to a
hex string. (If you're interested in the actual code to accomplish this,
you may find it in {php_source_directory}/ext/session.c, _php_create_id(),
and {php_source_directory}/ext/standard/lcg.c, php_combined_lcg()).

I am trying to remove the header and footer to create a printer friendly

remove header and footer when they visit: file.php?action=print
?php
include(../config.php);
if($_GET[action] == print)
{
$header = str_replace('include($header);', '', $header);
$footer = str_replace('include($footer);', '', $footer);
}
include($header);

// html
?php include($footer); ?
[snip]
Hmm - can't work because the variable $header doesn't include the string
include($header);.
Try it this way:
?php
include(../config.php);
if($_GET[action] == print) {
$header = null;
$footer = null;
}
if ($header) include($header);
?
// html
?php if ($footer) include($footer); ?

Re: [PHP] can't get any string replacements to clean this

A search on: [snip] I just found this thread, pardon me if I'm off topic, but something like this should work for you. It makes use of the fact that all of the replace functions can take arrays as input parameters. $from = array(/(\r\n)+/, /(\n\r)+/, /(\r)+/, /[\x0..\x19]/); $repl = array(\n, \n, \n, null); $str_cleaned = preg_replace($from, $to, $str_uncleaned); This construction should convert the occurrence of one or more successive newline combinations with a single newline character, and remove control characters at large (untested). -- O Ernest E.

Re: [PHP] OT Inactivity Timeout
At 17:03 14.03.2003, Luis Lebron said:
[snip]
This may be more of a javascript question than a php question. But how can I
set up an inactivity timeout that will logout a person after let's say 20
minutes of inactivity?
[snip]
That's an interesting question - something that might be handled
server-side (which is usually a lot safer than on the client side),
supporting (javascript-based) client requests if it is still logged-in.
I have tried a quick sample and believe a scenario like this could work
quite well in a production environment:
(1) handle login status server-side:
After authenticating the user, establish a timeout until that the login
will be valid WITHOUT user interaction (you may e.g. choose 5 minutes, i.e.
time() + (5*60)). Store this timeout value in session data
($_SESSION['login_valid_until']);
(2) update the timeout on every user interaction
Simply refresh the session based timeout value using the same formula.
(3) Have a special entry (either a special script, or a certain parameter)
where the client may ask if the login is still valid. Make sure this script
(and only this!) DOES NOT increment the timeout value since it will be
called by client javascript, not by user interaction.
(A) Header pseudocode for interactive pages (normal application scripts):
login valid and validates against timeout?
NO: transfer to you have been logged out page
YES: increase timeout; continue processing;
(B) Pseudocode for timeout-checking script:
login valid and validates against timeout?
NO: transfer to you have been logged out page
YES: return 204 no response status code
(C) Javascript to be used on any page:
script language=JavaScript
function checkHandler() {
window.location.href=yourcheckscripthere.php??php echo SID; ?;
onloadHandler();
}
function onloadHandler() {
setTimeout('checkHandler();', 6);
}
/script
body onLoad=onloadHandler();
The main feature here is the use of the server status code 204 which means
No Response. Cited from RFC2616 (HTTP 1.1 draft standard):
10.2.5 204 No Content
The server has fulfilled the request but does not need to return an
entity-body,
[...]
If the client is a user agent, it SHOULD NOT change its document view from
that which caused the request to be sent. This response is primarily
intended to allow input for actions to take place without causing a change
to the user agent's active document view, [...]
The 204 response MUST NOT include a message-body, and thus is always
terminated by the first empty line after the header fields.
So: if the server sees the login status (in session data) is still valid,
the reload request issued by JavaScript doesn't lead to a new page but lets
the browser remain in idle mode. However the timeout needs to be set
again; it seems that the JS engine clears all timers _before_ the reload
request (which would make sense; it can't clean them up on another page).
However if the server sees the user has exceeded its timeout (by not
activating some interactive action that would cause the timeout to be
extended), the javascript reload will immediately transfer the user agent
to the you're outta here page.

Re: [PHP] IF statement madness
At 19:21 14.03.2003, James E Hicks III said:
[snip]
Help save my sanity! What can I do to the IF statement in the following
code to
make it print the line that says By God they are equal in value.? I have
tried
the following changes;
1. using === instead of ==
2. placing (float) in front of the $i and $target inside and before
the IF
statement.
?
$start = 215;
$end = 217;
$target = 216;
for ($i=$start; $i=$end; $i+=.1){
if ( $i == $target ){
echo (BR$i - $target, By God, the are equal in value.);
} else {
echo (BR$i - $target, Eternal Damnation, they aren't
equal!);
}
}
?
[snip]
Before the if statement in your loop place this line:
echo \$i is now: $ibr /;
You'll notice that most probably your $i variable will miss $target by some
hunderths or thousandths, since you're working with it as a float. This is
due to the way fp numbers are stored and calculated (using exponents and
mantissa).
Workaround: don't use floats if you want to hit a certain value at the spot:
?
$start = 215;
$end = 217;
$target = 216;
for ($i=($start*10); $i=($end*10); $i++){
if ( $i == ($target*10) ){
echo (BR$i - $target, By God, the are equal in value.);
} else {
echo (BR$i - $target, Eternal Damnation, they aren't
equal!);
}
}
?
