Question

I have created an array of data, from which I can loop through specific fields and echo these values out, but what I need to do is add these values to a new array, ultimately allowing me to find the average of the values in the new array. As i’ve said, I can echo out the data, and I think I’ve figured how to get the average, if only I can create the new array! Any help would be greatly appreciated as I just can’t find the answer anywhere, and I’m running low on talent!

My table contains approx 25 fields, im pulling out a number of rows based on a session variable. In the instance im working on, I need to take just the values from 1 column in the table, and add these to an array. The code below will loop through the values, and echo them out, 1 at a time:-

while ($cdarray=mysql_fetch_array($calldata))   {
echo $cdarray['score_total'];
}

This gives me 25555 which are the 4 values I would expect 25, 5, 5, 5

I’ve tried

while ($cdarray=mysql_fetch_array($calldata))   {
$cdts = $cdarray['score_total'];
$cdtsar = array($cdts);
}

Which results in $cdts being assigned a value of 5,

Any help greatly appreciated!!

Answer 1

This will get your data from the array, place it into a new one and calculates the average.

$cdtsar = array();

while ($cdarray=mysql_fetch_array($calldata))   {
 $cdtsar[] = $cdarray['score_total'];
}

$average = array_sum($cdtsar) / count($cdtsar);
