Hi,
How can i destroy an array?
I mean i have a loop and for each new value in the loop i want to destroy the
array. Something like that:
while($row = mysql_fetch_array($result))
{
$product[] = $product_id;
// some code here
}
I've tried this but doesn't work
while($row = mysql_fetch_array($result))
{
$product = array();
$product[] = $product_id;
// some code here
}
To destroy an array?
First of all, where does $product_id come from? You gave us no code
that gives us that.
Second, if you're trying to make an array populated with a feild from
each row returned, your first example will work, but not the second.
The second example will empty the array, and start a new one (which
doesn't make sense to me why you would do that--because in the end,
you're only going to have the array with the last row returned).
But if you're trying to destroy an array doing either:
unset($an_array)
or $an_array = array();
will do the job.

Re: [PHP] radio buttons in $_POST
None input type=radio checked name=radio_test value=None /
And if you didn't want it to show to the user (because they have to
make a choice anyway) . . . you can use this css:
input[value=None]
{
display: none;
}
You should then always have a value to play with in PHP, and the user
doesn't see any extra clutter.

You want 2 or more decimal positions, so as if there are more than 2, to leave what exists. But your first example, you truncate the last 0.

[PHP] Re: [PHP-DB] How to get PHP to download web contents
Steve B. wrote:
How would you get PHP to download a file such as a web page and put it in a string?
What keywords would relate to this (besides php download)
I need a user to be able to put in a name and pass and have PHP go to a cetain site.
The site can take the user/pass in the url so I do not need a form submit.
Then I need the site contents to be in a php variable.
Any tips on parsing html out of it would be great.
Thanks
$fp = fopen(/http://site.com/path/to/file/;, r);
while (!feof($fp)) {
$buf .= fread($fp, 1024);
}
fclose($fp);
I like this method more than using file(), just because I have more
control over what happens. Since you're reading as its downloading, you
can do stuff with the data before you're finished.
As for parsing HTML... regular expressions are very cool.

And, Red Hat 9 comes with 2.0 so it's really confusing. Has anyone had any experience with this combo? Thanks, Jeff When someone says UNIX, they're generally including Linux and BSD, as both are UNIX clones.

Re: [PHP] Java Applet to PHP Communication
Sharat Hegde wrote: Hello, I need to be able to communicate from a Java Applet to a PHP program on the server to enable Live Connect for data. This is what I intend to do: In my web application, a Java Script program will call a Java Applet which then calls the PHP program on the server. The PHP program works like a servlet and passes the result back to the Java applet which passes the information back to the JavaScript program. How can a Java applet work with a PHP program? Are there any special precautions / programming issues involved? Thanks in advance With Regards, Sharat Not anything that you wouldn't have to pay attention to in passing stuff between applications in other instances. I'd use XML/SOAP to pass around the data. There are many reasons to do this, I wont list them here just because there are plenty of articles on the web advocating the use of XML.

Re: [PHP] a question, need an answer
what is the diffirent between :
//
session_start ();
$_SESSION['eventid'] = 'arma2';
///
and
/
session_start ();
session_register('arama2');
///
Regards
Nabil
Both accomplish the same thing, except how you are using it might not be
what you expect.
$_SESSION['eventid'] = 'arma2';
will assign the string arma2 to $_SESSION['eventid'] (obviously).
session_register('arama2');
will make the variable $arma2 a session variable. I believe you want
session_register('eventid')
The session_register way of doing things makes it act a lot like register_globals is on. It seems like we're trying to move away from this style of coding, so I'd suggest you use the first method with the $_SESSION variable.

Re: [PHP] TIP parsing form row data into variables
Nothing appears blatently wrong in the code you provided, but it's 4am
here, so I might be off.
This comes to my mind:
1. $_REQUEST was available from PHP 4.1.0 and later, are you using
somthing before that?
2. I assume you're doing somthing with $e_id within your loop, or else
you're just resetting the contents of it.
3. You might want to try print_r($_REQUEST) to see if it contains what
you think it contains.

Hi all,
This might be well known, so apologies if I'm going over old ground - I've
not seen this explained this way.
Last year I did a site using the variable variables method to parse row
data.
Now that I've moved to globals=off, I couldn't get that to work so I tried a
few other options settling for the following:
('howmany' is the number of form rows on the previous page)
$howmany = $_REQUEST['howmany'];
for ($index = 1; $index $howmany; $index++){
$e_id = 'e_id'.$index;
$e_id = $_REQUEST[$e_id];
Then do something with it.
Hope this helps someone.
