php assistance needed

I have 3 tables

TABLE 1 COLUMNS:

`test1`(`id`, `title`, `URL`, `img`, `tagsv`

Select allOpen in new window

TABLE 2 COLUMNS:

qa_posts (type, categoryid, userid, created, title, content, tags)

Select allOpen in new window

TABLE 3 COLUMNS:

qa_postmetas (postid, title, content) 

Select allOpen in new window

- I am looking for php script which will get data from table 1
- if TABLE 1 content column value doesn't exist in qa_postmetas
THEN
- INSERT (recursively)

INSERT INTO qa_posts (type, categoryid, userid, created, title, content, tags) 
(SELECT  'Q_QUEUED', '1', '3', NOW(), f.title, f.img, f.tagsv 
FROM dev.test1 f) 

Select allOpen in new window

and then
- GET inserted postid from qa_posts and insert values from table1 in table 3

qa_postmetas (postid <-- (this is what we have just inserted in first insert),
 title, <-- this is hard coded value 'qa_q_extra'
content <-- this is coming from table 1 (URL column)
) )
