PHP - Arguments Which Have & Within Them

I need someone to explain how to loop through an array ($products) and grab the three values (name, price, & shipping) and have them sent to "all_products" function - see line 13 then 61 thru 64.

I currently have the script partially working by using array_shift which I know is removing the 1st element (name or $product value).
Note: this is the problem (I need $product included in the call to the "all_products" function along with $price & $shipping so that the final output looks as follow:
---------------------------------

Checkout
Below is a summary of the products you wish to purchase, along with totals:

    * Candle Holder: $12.95
    * Coffee Table: $99.5
    * Lamp: $42.99


Total (including tax and shipping): $182.12
------------------------------------------------------

HERE'S THE SCRIPT FOR REVIEW & COMMENT:
===============================
<B>Checkout</B><br>
Below is a summary of the products you wish to purchase, along with totals:
<?php
 
/*
Fix this code by creating a function to determine sub-totals for each product. Then add the sub-totals together to arrive at the grand total.The product name, & price should display for each item.
 
?><ul><?
 
/* "all_products" function was created to query then calculate the sub-totals for each prodcut, then add each sub-total togehter to form grand total - outside the function */


function all_products($prod_array) {
   extract($prod_array);
   
   #tax rate is constant
   $tax = 0.08;
   $total_price = 0;
   $total_tax = 0;
   $total_shipping = 0;
   
   // Calculations per product with returned sum sent outside to $grand_total variable
   $total_price += $price;
   $total_tax += $tax * $price;
   $total_shipping += $shipping * $price;
   $sub_total = ($total_price + $total_tax + $total_shipping);           # This calculates the sub-total (or Grand total) for each product
   echo "<li>".$product.": $".$price."<br />";         # THE PRODUCT NAME & PRICE SHOULD DISPLAY HERE (NAME IS NOT SHOWING WHICH IS PROBLEM)
   # I had echo statement to confirm calculation on product was correct
   # echo "Grand Total is $".$sub_total."<br />";
   return $sub_total;  # This breaks out of the function when Candle Holder IF statement is true; returning value
}

/*
Keep the functions, and add a two-dimensional array that acts as a product database -- it should contain the name, price, and shipping price for every product -- and use list() and each() to traverse the database.
*/
 
// Products array with List / Each configuration to pass arguements into function
$products = array('Candle Holder' => array('price' => '12.95','shipping' => '0.00'),
            'Coffee Table'=>array('price' => '99.50','shipping' => '0.10'),
            'lamp' =>array('price' => '99.50','shipping' => '0.10'));
            
 
while (list($k, $v) = each($products)) {
   $product = $k;                                                                                                                                           
   # This is individual product name extracted from array
   #echo "Here's the price & shipping cost for ".$product.":<br/>";
   while (list($key, $value) = each($v)) {
      if (array_key_exists('price',$v)) {
         $price = $value;
         #echo "The product ".$key." is: $".$value."<br />";
      }
      if (array_key_exists('shipping',$v)) {
         $shipping = $value;
         #echo "The ".$key." cost is: ".$value."<br />";
      }
 
   }
}

# THE BELOW THREEE LINES TRAVERSE THE ARRAY BUT STRIPPING THE 1ST ELEMENT WHICH IS NOT WHAT I WANT; I NEED THE INCLUDED TO DISPLRAY BEFORE PRICES
$sub_total1 = all_products(array_shift($products));
$sub_total2 = all_products(array_shift($products));
$sub_total3 = all_products(array_shift($products));

 
echo "RESULTS OUTSIDE FUNCTION: ".$sub_total1."<br />";
echo "RESULTS OUTSIDE FUNCTION: ".$sub_total2."<br />";
echo "RESULTS OUTSIDE FUNCTION: ".$sub_total3."<br />";
// Add total sum for each product to define grand total for all products including shipping & taxes
 
$grand_total = $sub_total1 + $sub_total2 + $sub_total3;                             
 
?>
</ul>
<hr>
<br>
<?php
# Below is the "GRAND TOTAL" for all three project - displayed outside the function which should be $182.12 USD
?>
<B>Total (including tax and shipping): $<? echo number_format($grand_total, 2); ?></B>

The Business Logic is: If product is already purchased, upgrade the product

I have a customer input form to get information, along with some fields which should be auto populated based on what the customer chooses.

Screen Shot:

    https://i.stack.imgur.com/Fkyim.png
Note: Price and Shipping Weight are done with Ajax,

When we come to the shipping cost I am getting it from Magento, using a PHP function.

form :

     https://paste.ofcode.org/335FVUhpBGbazQtrcPLVQUs
PHP :

sp_cost.php

     https://paste.ofcode.org/hvG2sP9TW9CEPgMMuKXNuw
From the above code I am given the predefined value,

$results = getShippingEstimate('14419','1',"IN","642001");

How can i get country and zipcode from the user entry and return the shipping cost?

In my view file, I instantiate User class and call two methods that have not been declared or initialized in the class:

$user = new Models\User();
$user->setFirstName('John');
$user->setLastName('Merlino');

echo $user->getFirstName() . " " . $user->getLastName();

However, I have two private members only available to instances:
   protected $first_name;
   protected $last_name;

Because I don't want to manually create privileged getters and setters for each of my private members, I use the call method:

   public function __call($name,$args){

      echo $name . "<br />";
      echo $args . "<br />";
      
   }   

Because my methods were not initialized, the interpreter calls the __call method as a last option resort, and passes the name of the method in local variable $name and if exists the arguments passed into the method in local variable $args. Ok so that makes sense. However, when I echo the values of the two variables, I see a blank array created:

setFirstName
Array
setLastName
Array
getFirstName
Array
getLastName
Array

See everytime I call it, there's an array being created. I don't see the purpose of this.


Also how often do you use __call() in your php applications, specifically when using MVC?

Thanks for response.

Hello,

I was trying out some code to check out how some of the php settings work and when i tried allow_call_time_pass_reference to see if it works, it doesn't spew out any warning or error like the comments in the .ini file mention (or in the manual sites). Maybe i'm not using some other setting in order to see this? Here is my EXACT code.


<?php
ini_set('display_errors',1);
error_reporting(-1);


$variable = 'String';

function display($variable) {
return $variable;
}

echo display(&$variable);
?>


Outputs : String. No errors, no warnings.
I'm running PHP Version 5.3.2-1ubuntu4.5

 I am using a PHP class (it is attached) for Google Analytics that I got from this link below:
http://www.acleon.co.uk/?p=173

Unfortunately, it appears the Class has a PHP error:
Warning: implode() [function.implode]: Invalid arguments passed in Galvanize.php on line 114 and line 181.

This is line 114:
setcookie('__utmc', implode('.', $this->UTMC), 0, $this->CookiePath, $this->getDomain());

Here is line 181:
$urchinUrl .= '&utmcc=__utma%3D'.implode('.', $this->UTMA).'%3B%2B__utmz%3D'.implode('.', $this->UTMZ).'%3B';

I did not see UTMC and UTMZ declared anywhere in the Class.

The class file is attached. Thanks for your help in advance.

Hello,
I'm just a beginner (and french sorry for my language) : have some pb with my little implode function.

Warning: implode() [function.implode]: Invalid arguments passed in /homez.xx/myPathHere/entete.php5 on line 6
I understand
1/ that one argument is missing but don't find the right syntax
2/ I have tried to turn this file on php5 with this extension (ovh is under php4)
Here is my code in page defining the value and where stay my query (entete.php5)

<?php
if (isset($theme)) {
   $t = implode(',',$theme);
   $lien = "aide.php5?theme=".$t;
   $aide = '<a href="'.$lien.'">'.$onglet[0].'</a>';
} else {
   $aide = "";
}
?>


Here is my code in page which show result (aide.php5)

$t = explode(',',$_GET['theme']);
$n = count($t);
if ($n == 1)  {
   $where = "id = ".$t[0];
} else {
   $where = "id = ".$t[0];
      for ($i=1;$i<$n;$i++) {
      $where .=  " OR id=".$t[$i];
   }
}
Hope someone kindly help me : thanks in advance
