[PHP] Re: [PHP5] Super constructor?
If i'm not wrong php has only 1 level of depth for child class. That means
you can only extends from 1 level up the class.
In your example you have the class OneMore that extends down from the
"grandfather" Base. It is not a problem in C++ but should not work in php or
either javascript.
Am i wrong?

Re: [PHP] Re: Cookie Security?
I would suggest (haven't tried to write code in details) to associate a random number in a variable each time you send a cookie (for new cookies anyway) and store the key (randomvariable<->cookie) ina database. You should be able to verify the user at next connection verifying the matching key.

Re: [PHP] Active windows
Very hard (impossible) to control user activities by php-scripting. You are talking about client-side actions while php is only server-side. You should check for javascript client-side coding help.

Re: [PHP] how to iterate over fields names with mysql_fetch_assoc
Something easier:
while ($row=mysql_fetch_assoc($result)) {
foreach ($row as $k=> $val) {
switch ($k) {
case 'artist_name':
// do sometihing here, you may want to use $val;
break;
case 'urlPath':
// do something here you may want to use $val;
break;
default:
// do default action in case none is matching case value
(default is optional)
}//end switch
}//end foreach
}//end while
You need to go through the $result anyway, remember that $result is a
"resource" type it is wath is called a "recordset" in asp, it's kind of
object you have to "manipulate" to extract information from.
