Question

I have a table for users. But when a user makes any changes to their profile, I store them in a temp table until I approve them. The data then is copied over to the live table and deleted from the temp table.

What I want to achieve is that when viewing the data in the admin panel, or in the page where the user can double check before submitting, I want to write a single query that will allow me to fetch the data from both tables where the id in both equals $userid. Then I want to display them a table form, where old value appears in the left column and the new value appears in the right column.

I’ve found some sql solutions, but I’m not sure how to use them in php to echo the results as the columns in both have the same name.

Adding AS to a column name will allow you to alias it to a different name.

SELECT table1.name AS name1, table2.name AS name2, ...
  FROM table1
  INNER JOIN table2
    ON ...
