How to print a value from mutiple arrays in PHP?

e.g. Here is the structure I have and I want to print filepath from these arryas, here it’s clear that we have two arrays but in my case it’s dynamic. How can I print filepath from unknown number of arrays?

[field_pic] => Array
    (
        [0] => Array
            (
                [fid] => 29
                [uid] => 1
                [filename] => 011.jpg
                [filepath] => sites/default/files/011.jpg
                [filemime] => image/jpeg
                [filesize] => 154608
                [status] => 1
                [timestamp] => 1349463183
                [list] => 1
                [data] => 
            )

        [1] => Array
            (
                [fid] => 31
                [uid] => 1
                [filename] => 019.jpg
                [filepath] => sites/default/files/019.jpg
                [filemime] => image/jpeg
                [filesize] => 158635
                [status] => 1
                [timestamp] => 1349463188
                [list] => 1
                [data] => 
            )
    )

try:

for($i = count($field_pic) -1 ; $i >= 0 ; $i-- ){ //You have to substract 1 to the array length because it's of bound
    echo "filepath=" . $field_pic[$i]['filepath'];
} 

Example :

$arr = array(1,2,3) 

Count($arr) = 3;
but `$array[3] = undefined;
