The text file looks something like this

2
6
3

4

and its name is poll_data.txt

can someone please help me write some code that can add up all the numbers?

thanks

Hi Gantic,

You can try to use file open command to read the content of the file, then the summasion part will be a breeze. Sorry, I didn't put down any script here.

To expand on the previous answer, try:

$poll_values = file("poll_data.txt");
while(list($line_num, $value) = each($poll_values)) {
$total_value += $value;
}

echo "Total: $total_value";

Basically, file() gets the contents of poll_values and puts them into an array (each line is a seperate entry in the array) look this up at:

http://www.php.net/file

then, we loop through them and continue adding the values for each line. Once this is done, you will have the total value. Hope that helps!
