3) Execute the query:
4) Assign the data which you pulled from the database (in the preceding step) to a variable.
Here I used the parameter PDO::FETCH_OBJ that returns the fetched data as an object. If you’d like to fetch the data in the form of an array, use: PDO::FETCH_ASSOC.
5) Make sure that you were able to retrieve the data from the database, by counting the number of records.
6) In case that the query returned at least one record, we can echo the records within a foreach loop:
