Hello,
I'm having trouble getting the referring url. I have tried:
$HTTP_REFERER
getenv(HTTP_REFERER);
$_SERVER[HTTP_REFERER];
... but they are all blank.
The referring page has a meta http-equiv=Refresh header. If the user
waits for the page to automatically redirect, the referring url is
empty. If on the other hand the user clicks the link to the new page,
the referring url is fine. Is there a limitation here?
I'm familiar with using header(location..), but it doesn't allow a delay
time to be specified. Any ideas?

Hm. Too bad they don't have that "read a sample chapter" set up yet.
That's a feature I don't usually use (there's a Barnes and Noble and a
Borders near me if I want to read), but in this case would be nice.

You pretty much summed up my viewpoint.
No I haven't heard any more, but Rasmus has been a bit busy having his
hand crushed and practicing baby noises, so he's probably in no shape to
respond just yet!
All I can find repeatedly says 'any day now', but there's no hard data
beyond what can be seen (your (IMHO valid) comment notwithstanding) at
the O'Reilly site.
Am not keen to put in an advanced order, sight-unseen; and the man is
usually right here, so ...

Hi list,
I'm developing an CMS, and I started a session with PHP 4.1.1
With I use this in javascript "alert(document.forms[0].elements[0].name)"
it returns "PHPSESSID" and if i use
"alert(document.forms[0].elements[0].value)", it returns a number.
It's a bug???
I'm using IE5 in macos 9.2.2
Thank's in advance

Here's a little piece of code that gives me a weird problem:
<?php
if (!$logout)
{
if ($_SESSION['loggedin'])
{
unset($_SESSION['loggedin']);
}
}
?>
I have the session started and everything, but it gives me the following
error.
Warning: Undefined variable: logout in c:\inetpub\wwwroot\uslogin.php on
line 13
I've seen this used on several examples. I know that if I just use
empty($logout) then it'll work ok, but I just wanted to know why it's used
in so many examples but doesn't work in my code. Is there some setting that
I have set wrong or something? Thanks,

I understand your confusion. The thing is that empty() and ! are two
completely different arguments.
if(empty($var)) is looking for: $var = '';
if(!$var) is looking for: $var = false; or $var = 0;
If $var is set to anything other than 0 or false then the ASCII value of
the string is (by definition) equivilant to an integer value of 1 or
more. And thus is interpreted as true.
Hope that helps.

Hi,
Ive got an array of associations like this:
[1]=>2 [2]=>3 [3]=>4 etc
I want to add a new element [8]=>6.
How do I do this? I have tried several ways: pushing the element,
merging arrays, etc with no luck (it either increments the key or doesn't
work at all).
Any ideas would be appreciated!
Cheers,
Brad

I'd think $arr['8'] = 6 would work...
Using a number (as in $arr[8] = 6) would possibly confuse things, though
I can't get to a PHP machine right now so I'm not sure.

Have you tried just directly setting this array element? You don't say
what your array is named, so I'll call it $array.
$array[8] = 6;
Is that what you are talking about?

Hi,
I'm having a problem dealing with #'s in my urls. Most browsers will
not send the # with the request because they know it's only for use
with a named anchor.
so when you type in: http://mysite.com/test.php?id=0#top
all that the browser will send as a request is
http://mysite.com/test.php?id=0
this is good. My problem is when a weird browser sends the #top as
part of the request. when this happens, the value of id is now
"0#top". I need to make sure this doesn't happen. I know I could do
some ereg_replace on all my variables, but I would have to do this on
every request and I'd rather avoid it.
in php.ini there is a variable called arg_separator.input that looks
like it can help but when I add the line:
arg_separator.input = "&#"
I still get $id = "0#top"
so it doesn't seem to be working. I have php 4.0.6
thanks for any ideas,
- Mark

Did you restart the server after modifying php.ini?
As for "http://mysite.com/test.php?id=0#top"; sometimes resulting in id='0'
and sometimes id='0#', perhaps this is a situation where letting PHP
register the globals automatically is not the way to go. You could instead
extract the query string from the URL by using parse_url()
<http://php.net/parse-url>, then turn that query string into variables by
using parse_str() <http://php.net/parse-str>.

Yes you can, though it might be an inefficient way of doing it unless
you have some reason to do it this way. Look into the column type
"BLOB" (binary large object), it lets you store binary large objects,
such as images or files or anything, really.
Why inefficient? Well, for one thing, BLOBs don't retrieve as quickly
as regular fields, for reasons I don't altogether know. Also, you won't
be able to form a query to search for any characteristics of a BLOB,
since MySQL will treat the BLOB as a BLOB and doesn't try to imagine
what's inside it -- as opposed to, say, a VARCHAR column. There is also
a TEXT column type for very long text strings, and I forget whether or
not the contents of these can be used in queries -- can someone please
confirm this? But basically, almost any other column type is valid
subject matter for forming queries.
But for storing images and PDFs or other binary data, there's no other
way.
Note that many MySQL wizards will recommend that instead of storing
binary data in a database, use a filesystem to store the data and then
use the database to create a sort of "directory" for quickly locating
those files in the filesystem, remembering the path to the file or
something. I think this is how a lot of web sites incorporate graphic
content in with their database (text) content (including mine).

Actually, after having some problems with BLOB columns when
mysqldump'ing and moving the data into a new database, I did
find another way. I borrowed a trick from MIME mail handling,
and base64_encod'ed, then chunk_split'ed the data. This makes
it very text-field friendly.

There's a problem with this, it assumes that you only use one
filesystem for your site. In the case of Melbourne IT / INWW,
we have 5 or 6 web servers that load balance. If a user uploads
data and we copy it to the filesystem, then it's only available
on 1 web server. This is why we put it in the database. :)

Good day,
This isn't really on the topic of PHP.
But, to answer your question- yes, MySQL will let you do lots of neat things
with those large text fields, like looking for substrings and such. If you
want to store some text information, even that which might have special
characters, line feeds and so forth, the "TEXT" field is definately the way
to go.

You must place session_start() before any other /output/. It can come
after other code, as long as nothing will be output before it.
Alternately, you can turn on output buffering and just not worry about

When they say that you need to put session_start() before the headers,
they're referring to the HTTP headers, not the <head> tag of the HTML
document. HTTP headers are information about the document that tell the
client what to expect as it receives the document -- this helps the
client decide how best to handle the document. For instance, your
client (web browser) might be configured to print any text files
directly to the screen, but any XML files need to be parsed properly
before being printed. Or perhaps you're not even being sent a document,
but rather an MP3 or a PDF. Your browser might want to know a bit about
the file that it is being served, before it goes ahead and displays the
data on the screen -- in the case of an MP3 or PDF, it might wish to
open up Windows media Player or Quicktime or Adobe Acrobat as a helper
application (assuming your browser has been programmed to do this).
You can learn more about HTTP headers here:
http://www.jmarshall.com/easy/http/
NB I haven't read it, I just googled that (but I think I will read it
later).

Because I'm not a hacker on the PHP engine, I don't really know but I also
saw this symbol when learning C++ recently. It is used in C++ as a shortcut
to dereferencing and accessing an objects properties/methods on objects
which are on the free store (heap). Normally C++ uses the dot operator to
access methods/properties (eg. "foo.do()"), but when the object needs to
first be dereferenced, then "foo->do()" can be used as a shortcut to
"(*foo).do()".
Of course, this doesn't help you at all does it :) But I thought it was an
interesting connection to C++ and maybe hints at how PHP internally manages
objects. Perhaps it's just a coincidence.

Used in conjunction with classes.
class Foo
{
var bar;
function Foo($bar)
{
$this->bar = $bar;
}
}
$foo = new Foo("foobar");
echo $foo->bar; // "foobar"
For interests sake here's the same in C++ (correct me if I'm wrong it's been
a long time since I used C++ or pointers).
class Foo
{
char *bar;
function Foo(bar)
{
this.bar = bar;
}
}
Foo *foo = new Foo("foobar");
cout << (*foo).bar; // "foobar"
// which also works as.
cout << foo->bar; // "foobar"

Hi
In search of the definition for your question, I've came across an
intersting Doc. Iam just giving here the snapshot of that.
In PHP terms, the toplevel directory would be the global
namespace, and the pathname separator would be ->. Thus, the names
$cart->items and $another_cart->items name two different variables.
Note that the variable is named $cart->items, not $cart->$items, that
is, a variable name in PHP has only a single dollar sign.
The above para is stated in PHP Manual
I done many tests on this operator, atlast I found that, its not only a
dereferencing operator to access a variable or method, rather its a
namespace seperator. We can create any hierarchy of name spaces with
this op., on an object after creating it with 'new'.
I'm still not clear about this.

I have a question about cookies,why is the time that the cookies
expired not same as the time that parameter of session.cookie_lifetime
set?
for example, I wanna the cookies expired 5 minutes later,what should I
do?I think I should set the parameter,as follow:
session.cookie_lifetime = 300
right?
But, after restart my apache server,I found the cookies maybe expired
after 2 minutes,not 5 minutes as I want.
why?

That is correct. You need to load the file into your script, make

Have you looked at $HTTP_POST_VARS (or $_POST, depending on version) or
$QUERY_STRING?

Hi,
I use PHP 4.0.6, I am not sure about $_POST but $HTTP_POST_VARS removes
duplicate entries. As far as $QUERY_STRING is concerned well I knew it
could do it but I want to use POST method.
Not that happy knowing that PHP doesn't support this feature when Java and
CGI-Perl can.

I think the coder actually has to do a little bit from time to time - PHP
is good but not _that_ good.
Just out of curiosity, what do you think would be the algorithm for
_writing to_ an ini file? How many sections does it have? What are they
called? What is the structure of the entries allowed in each section? How
many entries can each section have? What are the possible range of values
for any entry? Rhetorical question, don't tell me.
What I am saying here is that it is a lot easier to parse a file given
its basic structure, than it is to create a file based on that structure
but with a huge, almost infinite, number of possible entries.
In other words, you'll have to roll your own, using the file functions.

What's the error? That would certainly help us help you. It might even
help you help yourself.
I'm guessing that your php.ini file has gpc_magic_quotes on. If so,
don't manually escape the data you're submitting, since PHP does it
automatically.
> Any body knows how to stop and start the MySql service ?
Depends. Do you have control over the server? If so...
net stop mysqld
may do the trick for you.

Oh, so then in your script, you weren't using the addslashes() function.
Personally, I prefer *magic_quotes to be off, allowing me to precisely
control what I want to do with the input.

For portability, the best thing to do would be to check what the settings are
using get_magic_quotes_gpc(), get_magic_quotes_runtime() or ini_get() and act
accordingly.

Thanks again for your help last night Jim. I found another source that by
passes the middle man and this script (see below) is quicker. It works great
for ONE ticker symbol. Yahoo allows one to retrieve multiple quotes by
typing in comma separated tickers with no spaces. msft,rhat,^dji
The commas get turned into pluses. The multiple ticker URL for above tickers
is thus:
http://finance.yahoo.com/d/quotes.csv?s=msft+rhat+^dji&f=sl1d1t1c1ohgv&e=.cs
v
If I change $symbol = msft+rhat+^dji
How could I save all to a multi-dimensional array?

I have a file called dbconnect that stores all of my mysql information
(host, user, pass) up until now I have always just used localhost as the
hostname because it was on my local server. My question is what do I have to
do to connect to a different server? Do I just have to put in the computers
ip address?

Yes. Except:
If that server will allow a remote connection from yours, then you're
all set. If that server doesn't allow remote MySQL connections, you'll
need to have that mysql administrator allow remote connections for that
mysql user and/or ip.

Hello everyone,
I would like to know why you put this character (!) in front of this:
<?php
$var1 = "Hello";
$var2 = "hello";
if (!strcasecmp($var1, $var2)) {
echo '$var1 is equal to $var2 in a case-insensitive string comparison';
}
?>
Do you see the (!) in front of the strcasecmp() function? That! Why do you put
that there?
I'm trying to learn PHP, but it's been kinda hard. THANKS A LOT GUYS!

An ! means that the following statement should be false. So:
if (!isset($variable))
means "If $variable is not set"

Why don't you call the script as command line one and redirect output
to /dev/null.

Hi there,
I would prefer to take away the possibility for PHP to parse my
documents in the /uploaded/ directory.
What has to be written into the .htaccess file for PHP *not* to parse
*anything* therein (not .php, not .phtml, not .html, not .php3, not
.blah... in a word -- NOTHING).
It would be very bad when somebody could upload malicious code to my
server, wouldn't it!
Thanks!

I'm having the same problem -
I've been using the mail() command for quite some time now and it's been
working 100% and executing immediately.
Suddenly, this morning, it is taking about 60 seconds to send mail, delaying
the display of the php web page by that same amount of time.
I have checked the mail server and sending mail from the command prompt
(linux) and there is no delay there.
Does anybody have any clue? I even momentarily downgraded to 4.1.0 to make
sure it wasnt a bug in 4.1.2

Can somebody tell me how many variables can i store in one session,
or how many KB can one session resist
--- End Message ---

Guys,
I want to randomly pick one of a number of values, with given probability for each
item, e.g.
abc 50%
def 25%
ghi 25%
The obvious way is to take a list where the 50% item is given twice and then randomly
pick one, but what if I want to use a probability of 51.3% (and don't tell me of a
list with 1000 entries and 513 times the 'abc' item *g*).
This seems to be trivial, but I just can't think of a simple and proper way to do it.
Any ideas?
Regards,
Gunther E. Biernat
