count array values

how would I go about counting values of of an array like this;

name|20.00|age
name|40.00|age
name|50.00|age

and so on...

how would I add up all of the values of the second columns? e.g. in this case to get 110.00

any help would be appreciated

use preg_split("|",$arrayname) first
then count($arrayname)

since you will be looping through the file anyway, you can put this in your loop

PHP:

<?php
//$str = 'name|20.00|age';
$str = explode('|', $str);
$sum += $str[1];

?>

also look at http://us3.php.net/manual/en/function.array-sum.php

thanks, i was looking into array_sum but I couldn't get anything out of it

to use array_sum you'd do something like

PHP:

<?php

$lines = file('yourfile.txt');
$data = array();
foreach($lines as $key=>$line)
{
    list($data['names'][$key], $data['count'][$key], $data['age'][$key]) = explode('|', $line);
}
echo array_sum($data['count']);
?>
