By now you may have a few databases.  You might want to move those databases to another server.  You might just want to back up the databases regularly in case you break them or data gets deleted.

Export (back up)The tables in intsql

In PHPMyAdmin make sure you have a database selected (click on a database name on the left).  Now click on the Export tab.  Press Go and your browser should download a file (if not see below).  This will contain queries to re-create all of the tables and data in your database.  If you have more than one database repeat the process.

If you got a Web page full of queries instead of a downloaded file you need to explore the settings.  Normally file download is the default but for some reason it is not on your server. 

Explore the other settings if you want to.  Be aware that PHP servers have limits on the time a page can take to load (to prevent crashes).  If you have a very big database then PHPMyAdmin may time out and not export everything.  Look at the last line of the file to see if it looks like the end of your tables.  This will normally only happen with large databases and nothing you have done so far comes close.  You can extend the times and limits in php.ini if you have access to that file.

Import (restore)

Once the file has been saved you can use the Import tab to do the opposite and import the tables and data to another database.  You would just browse to the file and accept the default settings by pressing Go but don't yet because you already have that database.

Do it?

Although exporting can do no harm you could accidentally mess up some data if you import tables into a database which already has tables with the same name.  This is very unlikely but do this carefully just in case:

  1. if you have the ability to created a new database then create one (using PHPMyAdmin) called imported
  2. check that you have exported all of the tables in the database you have been using for your pages as described above
  3. now export just one table by using the Export tab as before but this time click on custom and untick all tables apart from firsttable (or pick the one you think is easiest to replace if this goes wrong)
  4. if you could not create a new database in step 1: delete the table you exported using PHPMYAdmin (if you created a new empty database we will use that one)
  5. make sure the correct (new and empty) database is selected in PHPMyAdmin (imported or the only one you have)
  6. import the single table you exported

The table should now be (back) in your database.
