detecting number of variables

[Anon]

I am working on a shopping cart and I am outputting the items in variables that increment for the items. Ex: Name1 is the first item, Name2 is the second...

What I want to do is see how many the are. How can I do this? Right now I have it hard-coded to 100. Here is my code to display the items in a table.

<?
print "<table width=90%>";
print "<tr>";
print "<td width=70%>Description</td>";
print "<td width=10%>Quantity</td>";
print "<td width=10%>Price</td>";
print "<td width=10%>Item Total</td>";
print "</tr>";

print "<tr>";
print "</tr>";

for ($i=1; $i <= 100; $i++)

{
$temp_a = "Name$i";
$temp_b = "Quantity$i";
$temp_c = "Price$i";
$temp_d = "ItemTotal$i";

print "<tr>";
print "<td width=70%>".$$temp_a."</td>"; 
print "<td width=10%>".$$temp_b."</td>"; 
print "<td width=10%>".$$temp_c."</td>"; 
print "<td width=10%>".$$temp_d."</td>"; 
print "</tr>";

}

print "</table>";

?>

I'd use arrays myself. In the meantime:

$i=1;
for(;😉
{if(isset(${"Name$i"}))
$i++;
else
break;
}

$i is the largest number such that "Name$i" is the name of an existing variable.

try for insertion

<?

$items["name"][]=$curr_name;

$items["quantity"][]=$curr_quantity;

$items["price"][]=$curr_price;

$items["total"][]=$curr_total;

// this basically inserts a new item in the items array

// then

echo "THERE ARE ".count($items["name"])." ITEMS IN THE SHOPPING CART<br>";

//your code would be something like

print "<table width=90%>";

print "<tr>";

print "<td width=70%>Description</td>";

print "<td width=10%>Quantity</td>";

print "<td width=10%>Price</td>";

print "<td width=10%>Item Total</td>";

print "</tr>";

print "<tr>";

print "</tr>";

for ($i=0; $i < count($items["name"]); $i++)

{

print "<tr>";

print "<td width=70%>".$items["name"][$i]."</td>";

print "<td width=10%>".$items["quantity"][$i]."</td>";

print "<td width=10%>".$items["price"][$i]."</td>";

print "<td width=10%>".$items["total"][$i]."</td>";

print "</tr>";

}

print "</table>";

?>
