creating a sum from a variable result

[guymclaren]

Before anyone has a go at me, I have Googled, tried to create an array from the result and have failed miserably. In essence what I have is a result from a sql query multiplied with another giving me a row total.

 

while row exists
$var = $result1 * $result2 

Now I want to total up $var1 which could be a single entry or a list of entries. I have tried to create an array

               for($i = 0; $i < count($var); $i++){ 
	 		echo $var[$i].","; } 

Get no result, except ,

 

$val1 = array($var[$i]);
echo $val1;

No result

 

PLease help, my brain is not co-operating today.

Don't see why you need an array. Why not just have another variable in the while loop that totals up $var each time it loops?

 

Like...

$sum_of_var = $sum_of_var+$var;

 

Or am I misunderstanding?
