[PHP] next,key,current question

[Sara Daugherty]

I am having trouble with creating a list box.
I am attaching the code.
I am not sure the code in the for loop close to the end of the program 
is correct.

If someone could take a look at it I would appreciate it.

Thanks,
Sara

// This funciton sorts the values in the array.
asort($Classes);

echo "
This is using a while loop to create a list box.";

echo "";

// Here we use the while loop to display the values in the array in a list box.
while(list($ClassesKey,$ClassesValue) = each($Classes)){


 echo "$ClassesValue";
}

echo "";

echo "This is using a foreach loop to create a list 
box.";

echo "";

// Here we use a foreach loop to create a list box from the Classes array.
foreach ($Classes As $ClassesValue)
{

echo "$ClassesValue";
}

echo "";
//The ksort function sorts the contents in the array by its indexes.
ksort($Classes);

echo "This is creating a list box by manually 
iterating through an array.";
echo "";
// Here we will iterate through the array manually using a for loop and the 
next,current, and key functions.
for($i=0; $i<3; $i++){

echo "$ClassesValue";

next($Classes);
$CurrentIndexValue = key($Classes);
echo ($CurrentIndexValue);
$CurrentContents = current($Classes);
echo ($CurrentContents);
}
echo "";
?>

[PHP] tax functions

[Sara Daugherty]

Hello,
I am new to php. I am trying to learn functions.
Can someone look at my code and tell me if I am on the right track or if 
I am doing something wrong?
Here is the link where my script can be found:

Thanks,

[PHP] fighting with functions

[Sara Daugherty]

I could use a little help. click on the link to see my php code for a 
project that creates an array with a list or items and their cost and 
calculates tax by using a function called getTax() and also creates a 
balance by adding the cost plus the tax in a second function called 
getBalance(). I must also create a table where the cells automatically 
load so the end result looks like this.
http://www.areawebdirectory.net/taxtable2.txt

Item  Cost  Tax  Running Total
Car  1.00600  10600.00
Pencil   1.00   .0610601.06
Book14.95 .097 10616.98
I cant seem to first be able to declare my array and succeed at naming 
the key as item and the value as price. I have attempted to use 
variations of the following with no success.

$items = array (
   0 => array ("item"=>"car","price"=>15000, "tax"=>.065 ),
   1 => array ("item"=>"pencil","price"=>1, "tax"=>.065 ),
   2 => array ("item"=>"book","price"=>14.95, "tax"=>.065)
);

Without being able to declare the key as item and the value as price I 
am not sure how to pass these items into my function and I am riddled 
with error messages. I think my base problem is to either fix how I am 
declaring the array so I may reference "item" and "price" as I am now 
doing in my functions or learn how to change the functions accordingly.

I am also pretty sure that my functions are not quite right. I am also 
not sure how to link the right answers to get my table to print as above.

Please note that I have included a while loop after my array just to 
prove that my array is working. It is needed part of my program. I also 
have given each cell in my table some text just so I can find them when 
I have figured out how to create the right reference links.

I am sorry that I need as much help with this. Sadly I have been at this 
for almost two weeks trying to solve it.

Thanks,
Sara
