PHP & MySQL - How to count the number of times data was entered for a specific user?

Question

Let's say I want to display the tags related to users_question_id 1 and I want to count the number of times that tag was entered for that question by 1 each time it was entered in-order to display the tags that where entered more bigger.

How would I do this using MySQL and PHP I have created two tables called questions_tags and tags.

Here is the MySQL tables layout

Table questions_tags

id  tag_id  users_questions_id
46  46   1
47  47   29
48  48   1
49  49   11
50  50   1
51  51   1
52  52   345
53  53   1
54  54   1
55  55   100
56  56   1
57  57   1
58  58   1
59  59   1
60  60   1

And here is the second table.

Table tags

id  tag
46  a
47  x
48  a
49  r
50  a
51  a
52  k
53  a
54  a
55  q
56  b
57  c
58  d
59  d
60  z

Answer 1

I am out of time, but check out SQL for the count() function.

Answer 2

   SELECT t.tag,
          COUNT(q.tag_id) 'num'
     FROM QUESTIONS_TAGS q
     JOIN TAGS t ON t.id = q.tag_id
    WHERE q.users_questions_id = 1
 GROUP BY t.tag
 ORDER BY num DESC
