Question

i have a array that returns some numbers. and i want to add those numbers together and also count them.

here is what i have so far:

<?php
$homepage = file_get_contents('http://graph.facebook.com/215844978437619/reviews');
$parsed = json_decode($homepage,true);
foreach ($parsed['data'] as $key => $values){
$totalRatings1 = $values['rating'] ;
}
?>

what i am trying to do is to sum the $values['rating'] together and also count them.

So that: $totalRatings = sum_array($values['rating']) and $totalCount = count($values['rating'])

but i get lost in the sintax.

any ideas?
Thanks

<?php
$homepage = file_get_contents('http://graph.facebook.com/215844978437619/reviews');
$parsed = json_decode($homepage,true);

$totalRatings = 0;
$totalRated = 0;

foreach ($parsed['data'] as $key => $values){
   $totalRatings += (int) $values['rating'];
   $totalRated++;
}
?>

$totalRatings will have the aggregated sum of all ratings, $totalRated will be the count of how many ratings there are.
