Using php file first of all you need to take dump of multiple database using exec() and mysqldump as

exec("mysqldump --user root -p --databases test1 test2 > file.sql");

This will export multiple database into one file now you can import database into test3 using

exec("mysql -u username -p test3 < file.sql");

Assuming all of the table names are different and we are talking tables only (Im unsure on triggers and other operations) you could use the "Copy database to: " feature in PHPmyAdmin to do this follow these steps;

  1. Select the database test1
  2. Go to the operations navigation item along the top
  3. Go to the Copy database to: section and then enter test3 as the database you wish to migrate to. Copy Database To
  4. Repeat for test2

Since you mentioned phpmyadmin you can do this all in phpmyadmin.

First export both databases (test1 and test2) as SQL. You can follow instructions in this post. Then you can import both of these databases in into test3 using phpmyadmin also.

You probably want to make sure that there are no conflicts with table names to avoid test1 overwriting test2 tables (or vice versa). If you want to keep these tables separate then you can add a prefix to all tables but it really depends what you're trying to do. Since you're expecting 38 tables I am assuming that you don't want to mix the data.
