I hope this is not a stupid question, but I am learning how to work with
Arrays, and am having trouble figuring out how to move array values from
page to page and/or store in a db. Once again, I am new to arrays (and
fairly new to PHP for that matter), so please don't get too technical in
replies. Thanks so much for help.

Where is you (broken) PHP code that you have written so far?
What is it not doing that you are expecting it to do?

Hi Ben,
Welcome to the wonderful world of PHP.
Working with array in PHP is very easy. A large number of functions are
there.
Please visit the manual
http://www.phpcertification.com/manual.php/ref.array.html
You can move values ( including Arrays) from page to page in session
variables.
But you need to do serialize and unserialize in case of array or object.
Do ::
$val_ar=array("one","two","three");
$_SESSION['val_ar_store']=serialize($val_ar);
Now you can get your array in any page simply
$val_ar=unserialize($_SESSION['val_ar_store']);
Print_r($val_ar);
This process is very simple. Please see manual
http://www.phpcertification.com/manual.php/function.serialize.html
http://www.phpcertification.com/manual.php/function.unserialize.html
Revert back with any other problem.

There are a couple of ways to pass arrays (and their values) between
pages. I personally would put the array into a session variable
($_SESSION - see reference) and access the various parts as needed.
Another option is sending the whole array or it's parts as hidden fields
in a form (access with the $_GET and $_POST - again see reference), but
that means the user has to click a submit button.
If you are trying to store the array in a Database I would suggest you
make each element of the array into it's own column of the database.
Databases generally should only have 1 piece of information being saved
per cell (think excel). If you would like a link to database design,
let me know and I will send it.
If all you really were asking was how to iterate through an array - then
I would recommend looking at the manual's page on arrays (
http://www.php.net/manual/en/language.types.array.php ).

Thank you to all for help with this. Once I have a general idea of which
path to head down, I can figure it out pretty well from there, and you have
all given me a pretty good road map. Anyway, thanks again. It is greatly
appreciated. I'll let you know hot it all comes out.

Serialization is done automatically. You don't need to do it yourself.
You can even store simple value-objects in the session witout manual
serialization.
So you can do:
$val_ar = array("one", "two", "three");
$_SESSION['val_ar_store'] = $val_ar;
serialize/unserialize are useful if you want to store complex data in a
file or in a database.

Perhaps try to advertise it somewhere on your site, how to set it in
various browsers. People will use this once they realise the setting is
there. It's very nice to go to a website without doing anything special and
be greeted by your mother tongue. Once they experience this they will like
it.
HTTP_ACCEPT_LANGUAGE will look like this: ro,en-us;q=0.7,en;q=0.3
Comma is the main delimiter, separating languages. The "q" signifies
precedence among similar languages, such as en-us vs en. Otherwise, the
order in which the languages were given sets precedence.

Hi,
You may try a ip locator and then guess for users country.
IN this way you can design your programme to treat users from Russia to
Russian language etc.

I don't think it's possible. You can, however, ask the user to select
which language he wishes to see, then store that option in a cookie so
he doesn't have to do it every time he visits the site.

Dear all subscribers,
I'm coding a send-mail form, also including
edit boxes keeping the path of files to be uploaded

Is there the possibility (and if so, which ones) to
manage FTP permissions to have a file including
the variable with ID and PSW (for FTP access)
and which is usable
by the code running on the server exclusively but
cannot be accessed by any other user?

Your question is not very clear. Do you mean to say you only want your
FTP server to be accessible by your php scripts? If so the trick is to
listen only on localhost and not on the public ip.

No, only some of the scripts shall be

That's even more confusing. You run php scripts off a web server and not
an FTP server.

Ok ... the server I'm dealing with works for both services.
But let me re-explain the question in new terms.
I have a bunch of php scripts on a web server.
I just wanted to know if it is possible to deny access
permissions for some of such scripts to a public user
but not to other scripts staying on the same server.

Hi All,
I have written a simple page that uses fping and was working perfectly just
shelling out to it using the backtick.
The server it was on crapped out and I'm trying to get it going again on our
new server. I have installed fping, given permissions to everyone to run
it and copied it to the places where it was before. /usr/local/bin /bin
/sbin
And it will not return the input I give it.
Anybody in the house got an ideas? Idiot me didn't document what I did to
get it going in the first place...
Thanks
Matthew

And what, exactly, does that mean?
- what did you do?
- what did you expect to happen?
- what actually happened?
- any logs and error messages?
Not all of us are certified mindreaders, so some basic info would help.

Hello,
I am working on a site where people will be updating information in a
database and should have up to date info. Now since HTTP is stateless
the user will not know about any new information until they click on a
link or hit a button on the page.
My question is -- if I want to keep a user up to date about changes to
any information they might want to know would it be best to create a
hidden frame of some sort which does a mete-refresh to a page looking
for updates, and if found display a java popup window with a small FYI ?
If so would a meta-refresh of 3-5 seconds be to aggressive ? What about
server load ?
Is there a better way ?
Hope I was clear, thanks.

Hi Michael,
I always use
header('Refresh: 2; url=' . $_SERVER['PHP_SELF']);
to reload the current page every 2 seconds. You may want to pass $_GET
variables, depending on your needs. Also make sure you call this function
_before_ any other output has gone to the browser.
HTH,
Ivo

I am also running turck with php5 without too many problems and that's

One example: I'm using osCommerce, which is not using any new
PHP5-features (It's PHP4 software) but it is using general OO. And the
results if MMCache is enabled are very unstable. Most of the time the
HTML output is corrupted. Sometimes it segfaults. These problemse go
away if I disable MMCache. On PHP4 everything works fine with MMCache.

Hi guys and gals,
I'm not screaming "Bug! Bug!" but this _does_ look 'illogical' to me. I've
searched the archives, but found no earlier conversation. Sorry if
I missed it. Consider the following code:
var_dump(in_array('test', array(0)));
What does this return? I expect bool(false), but it returns bool(true).
After some searching the web, I bumped into this:
http://www.phpdiscuss.com/article.php?id=67763&group=php.bugs
Basically, it is said by derick [at] php.net that this behavior is
expected. The following code :
var_dump('test' == 0);
also returns bool(true). But my logic tells me, that if 'test' == 0, then :
if (0) {
...
}
should do the same as
if ('test') {
...
}
but it doesn't! The first if-statement is _not_ executed, the latter is.
In my opinion, this is not correct. Any thoughts on this? Am I not seeing
the logic here?
Thanks for your thoughts.

Apart from Marek's reply, you should probably check the in_array()
documentation (look at the third, optional parameter) and search for
type casting on php.net.

Hi guys and girls, while we are on this topic, has anyone got a good
senario of a sub select query which can remove the nested loops ? I
have been wanting to get rid of nested loops for a good while and now
Mysql 4.1 is out I would like to start using it. So the usual scenario
for nested loops to to get data out of a 1 to many relationship. Please
put me on the right path, I had asked the Mysql list but no success.

Well yeah.. It's hard to believe a well written MySQL sub select query
with proper indexing would be slower than looping through the results
with PHP scripting.
