RE: [PHP] Weight function.
Thanks.
I have just this minute got it working.
Basically the same function I used for determining price of the cart
items could be used for determining weight. All I needed to do was
assign my DB with a field called weight and call that instead of price
from the DB so my calculate weight function looks like this.
function calculate_weight($cart)
{
// sum total weight for all items in shopping cart
global $weight;
$weight = 0.0;
if(is_array($cart))
{
$conn = db_connect();
foreach($cart as $ItemCode => $qty)
{
$query = "select weight from products where ItemCode='$ItemCode'";
$result = mysql_query($query);
if ($result)
{
$item_weight = mysql_result($result, 0, "weight");
$weight +=$item_weight*$qty;
}
}
}
return $weight;
}
By making $weight a global variable I then call that in my shipping
function and set it's parameters:
function calculate_shipping_cost($weight)
{
//shipping costs calc. less than 10KG is 15 more than 10KG currently
20.
global $shipping;
if ($weight <= "1")
$shipping = "15";
else
$shipping = "20";
return $shipping;
}
I still don't fully understand why this works but am happy it does!

It is not for PHP. PHP may only insert queries and get results and another system computers all data. Such system is based on statistic or artificial neuron nets.

[PHP] xml parsing
Hi! I understand that it's easily possible to parse xml documents with php. But what about changing them? With other xml parsers, I have the xml document in a structure (usually a tree or an array) and when I change something in the structure I can later "write out" the structure again into a xml file and get a changed xml file that way. Is this possible easily with PHP too? Thanks Mike --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

[PHP] Is this a bad thing to do? (Unix permissions)
As part of my new site I have created a php-driven guestbook. The guestbook entries are stored in a file called guestbook.txt. I found that in order to get the script to write to the file, I had to set the directory permissions for the guestbook directory and the guestbook.txt file to -rw-rw-rw- ... is that a bad thing to do? Does it expose me to any hacking problems? If so, what should I have done? Bear in mind I'm using a 3rd-party host and I work in Windows, so please don't blind me with science ;) Thanks, Gwydion -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] php/frontpage
I'm not 100% sure, but I think the answer you seek lies in the server, and not php. You may have to set your webserver to reconize *.php as FP files that it needs to parse, or set it to where it parses *.htm for php. Is this running on IIS, Apache, or something else?

I don't know if there is an automatic way to do it, but if you know you are 5 hours ahead of GMT for example, and you want all records for Oct 17, 2002 GMT+5, then you could do this: SELECT * FROM your_table WHERE TO_DAYS(datetime_column + INTERVAL 5 HOUR) = TO_DAYS(20021017) You can use DATE_FORMAT() in your query to reformat the MySQL timestamp, or use UNIX_TIMESTAMP() to retrieve a unix timestamp instead and format it in PHP.

First of all... thanks for trying to help...
I'll show the full piece of code I made :

$fp = fsockopen($file, 80);
if (!$fp) {
echo "does not open";
} else {
echo $fp; -> Here is what I say it does't return anything. This
line is just to figure out what fsockopen() returns.
while (!feof($fp)) {
echo fgets ($fp,500);
}
fclose ($fp);
}
Thanks again

What do you mean "it returns nothing?"
fsockopen() returns a file handle. Was the file handle valid, i.e., not 0?
If true, then you must READ from the opened file handle.
Please, be more specific in your error discussion.
