Answer 1

$name = $array['name'];
$comment = $array['comment'];
$tags = $array['item']['tags']; // this will be an array of the tags

You can then loop over the tags like:

foreach ($tags as $tag) {
  // do something with tag
}

Or access each one individually

echo $tags[0];
echo $tags[1];

Answer 2

$name = $array['name'];
echo $name; // ajay

$comment = $array['comment']
echo $comment;  //hello world.. test comment

$tags = $array['item']['tags'];
echo $tags[0]; // javascript
echo $tags[1]; // coldfusion
