I have a multidimensional array that I am attempting to get a value of a key, so my code starts like this:
$doc = $data->field_field;
$print_r($doc);
which prints out this:
Array
(
[0] => Array
    (
        [rendered] => Array
            (
                [#markup] => link1 //what I want to grab
                [#access] => 1
            )
        [raw] => Array
            (
                [fid] => **
                [uid] => **
                [filename] => ****.docx
                [uri] =>****.docx
                [filemime] => 
                [filesize] => 
                [status] => 1
                [timestamp] => 
                [type] => default
                [uuid] => 
                [rdf_mapping] => Array
                    (
                    )
                [display] => 1
                [description] => 
            )
    )
)
I am trying to grab the value of [#markup] which is a link.
