I have designed a class that multiplies one of the varibles by two but when
i pass the values to the contructor i cant get the answer out any ideas
Here is the full script "If you can recognise the problem can you explain
why its wrong and why its not working "Ps learning the langauge "
The Class File
class purchase {
var $PartNumber;
var $Description;
var $Unitprice ;
// this is the constuctor
function purchase($partnumber,$desc,$price)
{
$this->PartNumber = $partnumber;
$this->Description =$desc;
$this->Unitprice =$price;
echo "Object created partNumber = $this->PartNumber <br>";
echo " This Objects Description = $this->Description <br>";
echo " This Objects Price is $this->Unitprice <BR>";
//this doesnt work why ??
echo " price * two is $this->Unitprice*2<BR>";
}// end constructor
}
$myObject = new purchase(1,"Speaker",23.00);
?>

echo() can interpolate a variable, but not an expression such as
"$this->Unitprice*2"
replace:
echo " price * two is $this->Unitprice*2<BR>";
by:
$bytwo = $this->Unitprice*2 ;
echo " price * two is $bytwo<BR>";

Sorry about this question "Im a novice at this "
Ok read all the info on this special variable but i still havent got a clue
what they are on about "Duh" yeah i know but if someone can put this into
plain english for me it would be helpfull
1: What does it do i see this included in forms for submission of values
acording to one tut it does the following but im still perplexed by this
As follows
Also note the use of the variable $PHP_SELF. This variable, which stores the
script's name and location, is passed along with every PHP page. It's
helpful here because we just want this file to call itself. Using $PHP_SELF,
we can be sure that will happen, even if the file is moved to another
directory - or even another machine.
2: Where would i use this and why would I use this. Whats its purpose can
any one give me an explained example " may be an algorithm or something "
>From what I understand is that if you use this on one php script then
calling another script with the variable $PHP_SELF contained within will
remember the previous script " <<< Now im really confused !!
Manythanks Mark

hey,
i use the var $PHP_SELF in a news board i have just finished. What i use it
for is some people rename it from news.php to something like latest_news.php
or anything else they want so in a form i use it like this
<FORM METHOD="Post" ACTION="<?Php echo $PHP_SELF; ?>?area=submit">
that will then print the following into the page code
<FORM METHOD="Post" ACTION="news.php?area=submit">
The $PHP_SELF is just a shortcut instead of writting the name into the
script it will get the full url of the script and the name an put it in for
you.
If i move a script from one dir on my computer say http://127.0.0.1/news/ to
http://127.0.0.1/new_news/ the $PHP_SELF will change from /news/ to
/new_news/ every time the script is called.
If you need help on any php var download a copy of the Php Man located on
the PHP.net site it comes in handy for things like this.

Are you sure you mean /r/n? I think you mean \r\n which is a windows
line-end..
