Begin building content navigation by reviewing basic database connectivity and learn how to loop through returned records in order to output a list of the subjects stored in the database.
- [Instructor] In this chapter, we will learn to build…the navigation that the public is going to use…to change the page content that they're viewing.…We'll begin by creating a list…of the current subjects in the navigation.…This is going to apply the skills that we learned…in part one of this course, and it also gives us…an opportunity to do a quick review…of how PHP interacts with the database.…If you'll remember, there are five basic steps…to PHP-database interaction.…The first is we need to create a connection to the database.…After we have a connection, we can perform…a database query, we can use the data returned…by that query, if any, and then finally…release the returned data when we're done with it.…
That frees up memory.…And then, when we're done with all of it,…we can close the database connection at the end.…Steps one and five are performed only once per PHP script.…Steps two, three, and four…can be performed one or multiple times.…Let's look at it in PHP code.…Here you can see I'm using the mysqli_connect function.…
