The DeveloperTutorials website has a quick new article today talking about the insertion of an entire array into a database:
A few days ago, a user came into #phphelp on UnderNet wanting to know how to insert an array into a database. A simple enough concept, but how exactly does one look up information on the subject? The goal is to take a form with multiple input sets (like a list of people, their phone numbers, etc.) and input multiple rows into a database.
They create the database and a simple form to get the array input from before sharing the code to grab the information and loop through them all and drop them into the database table.
