extract column from multidimentional array

Hi,

below you will find the code for a small script where i'm able to extract a row but not a column.

So the question is how can I do that.

Here is the code:

<?php

$arr = array(
array('00', '01', '02', '03'),
array('10', '11', '12', '13'),
array('20', '21', '22', '23'),
);

$row = $arr[0];
$col = $arr[][0];
print_r($row);
print "\n";
print_r($col);
?>




.
