Adding to variables
Can Someone help me with this? Is this possible?
<?
// This is an example ofthe parsed variable
$calc_qty1 = "Testing";
// This number is actually determined by the for loop but static for testing
$i = "1";

// I want this to echo the value of $calc_qty1 the last number as dictated by the loop value

echo "$calc_qty,$i";
?>

RE: Adding to variables
if the varnames always start with 'calc_qty' you coulde do

php Code:
Original - php Code 
  1.  
  2. $tmp_var = 'calc_qty'.$i;
  3. echo $$tmp_var;

RE: Adding to variables
But then the var would become an array

I see your point thought...

RE: Adding to variables
another way to do it would be:

php Code:
Original - php Code 
  1.  
  2. eval('$var = '.$calc_qty1 . $i';');
  3. echo($var);

RE: Adding to variables
I'm not sure here but doesn't eval() take longer to execute?
