Array sum

Hello,

I have an array:

Array
(
[0] => Array
(
[0] => line 1
[1] => 0
)

[1] => Array
(
[0] => line 2
[1] => 0
)

[2] => Array
(
[0] => line 3
[1] => 2
)

[3] => Array
(
[0] => line 4
[1] => 1
)

[4] => Array
(
[0] => line 5
[1] => 1
)

)

Question is: how can I sum $array[i][1] values. In this example $sum
should be $sum == 4.

TNX

$sum = 0;
foreach ($array as $value)
$sum += $value[1];
