Answer 1

Use array_filter(). Quick code test (doesn't necessarily mirror your situation, but you should get the idea):

 array('name' => 'samson'),
    1 => array('name' => 'delilah'),
    2 => array('name' => 'samson'),
    3 => array('name' => 'goliath'),
);

$md5Processed = array();

$newArray = array_filter($array, "uniqueMD5");

print_r($newArray);

exit;

function uniqueMD5( $data ){
    global $md5Processed;

    if( !in_array( $data['name'], $md5Processed ) )
    {
        $md5Processed[] = $data['name'];
        return true;
    }
}
