[SOLVED] calculating avarages

[kellz]

$people = array(
              'peter' => 22,
		  'markus' => 17,
		  'andrew' => 18,
		  'steph'=> 22,
		  'jhon' =>  22,
		  'anna' => 18
		  );

foreach ($people as $name => $age) {
echo "$name is $age years old.<br>";
}
echo '<br>';

$ages = 22*3+17+18*2;
$avg = $ages / 6;
echo "the avarage age is " . substr($avg,0,2);

 

i need a better way to do this, because that is a set array but when i finish i wont know the ages of the people... i guessed loooooping through the array and getting the value and adding them together then deviding the total but ugh it just went all messy lol.

 

and btw, this looks like something someone would do for homework but unfortunately my school doesn't offer nothing more than basic IT (word/excel/powerpoint)..ect..  :'(

$av_age = array_sum($people) / count($people);
