Question

How to sum values of index 'age' in multidimensional array PHP: $staff=array(array('name'=》'Berik', 'age'=》'30'), array('name'=》'Oleg', 'age'=》'25').
need to summ 'age' and then to find average number

Answer 1

You need to have the age as integer rather than string, so do as follows:
'age' => 30

Instead of:
'age' => '30'

<?php
$staff=array(array('name'=>'Berik', 'age'=>30), array('name'=>'Oleg', 'age'=>25));

$sum = 0;
$items = 0;
foreach($staff as $emp)
{
$sum += $emp['age'];
$items++;
}
$avg = $sum / $items;
echo "There are $items employees, with an average of age $avg years";
?>
