how to exclude element form array sum in php? - php

Question

i have this array:
[Jessica CS] => Array
(
[2011-04-20] => Array
(
[0] => 69.90
[cancel] => 1311145200
[1] => 29.95
[2] => 69.90
)
)
[Rex CS] => Array
(
[2011-04-20] => Array
(
[0] => 119.94
[cancel] =>
)
[2011-04-26] => Array
(
[0] => 199.50
[cancel] =>
[1] => 29.95
)
....
and i am adding together these values by using a loop:
$i=0;
foreach($dates as $d){
$total[$i] += array_sum($value[$d]);
#i++;
}
this will add everything together and what i want is to exclude the [cancel] field from being added to the array_sum
edit: i could probably add the values that are int, but not sure how to sort them
any ideas?
thanks

Answer 1

Personally I would change the layout of the array so that it went more like:
[Jessica CS] => Array
(
[2011-04-20] => Array
(
[cancel] => 1311145200
[costs] => Array
(
[0] => 69.90
[1] => 29.95
[2] => 69.90
)
)
)
Replacing [costs] with whatever name is most relevant.
Working with your existing array
Failing that
$i=0;
foreach($dates as $d){
$total[$i] += array_sum(array_diff_key($value[$d], array('cancel'));
#i++;
}

Just loop through the array, perhaps like this:
$input = array(
'Jessica CS' => array(
'2011-04-20' => array(
0 => 69.9,
'cancel' => 1311145200,
1 => 29.95,
2 => 69.90,
),
),
'Rex CS' => array(
'2011-04-20' => array(
0 => 119.94,
'cancel' => null,
),
'2011-04-26' => array(
0 => 199.50,
'cancel' => null,
1 => 29.95,
)
)
);
$totals = array();
foreach($input as $person => $dates){
$totals[$person] = 0;
foreach ($dates as $date => $values) {
foreach ($values as $key => $val) {
if ($key !== 'cancel') {
$totals[$person] += $val;
}
}
}
}
print_r($totals)
Produces:
Array
(
[Jessica CS] => 169.75
[Rex CS] => 349.39
)
