ok let say that you have 2 or more variables with same name but there are
difference in numbering And Values like this :
$var1 = 1 ;
$var2 = 12 ;
// etc ..
now you must now how much of number of this varibles before you deal with it
or you must store it on array to know how to count it in the fly like this :
$var[var1] = 1;
$var[var2] = 12;
// etc ..
$var_count = count($var); // give you the count
now you can deal with vars like this :
$i = 1;
do {
$NewVar["NewVar".$i] = $var["var".$i] * $WhatEver ;
$i++;
}
while ($i <= $var_count );
And finally you can extract vars by extract() to make them in normal shape
if you get my point
