How to put page phpQuery?

Help to solve this problem))
For example at one site there is a table::

Name: Alex
Text: Hello World!

Using phpQuery (foreach) I have spars all records from this table and recorded in the database, but for example after 5 minutes was added a new entry on the website, how can I re-put ? When re-parsing, whether to send a query to the database to check whether such a record ? And is it possible to do so if another site has added a new entry, then immediately and spartilas on my page ? Or make it so that every 5 minutes Parcelas page on another website
