Michelangelo Van Dam is back with another part of his series covering the use of arrays in PHP. In previous articles he covered some of the basics including operations and associative arrays but in this new post he moves up and talks about some of the other functions you can use to manipulate them even further.
In my previous article about arrays (the basics, simple operations and associative arrays or hash maps) I have shown what arrays are and what you can do with it. Now I want to dive into real fun and explain PHP's array functions with real-world examples and how you can apply them in your day-to-day work.
He then goes through several of the PHP array functions, providing simple code snippets of them in action. To help apply it to a more "real world" situation he uses data based on a "countries" table in a database, making use of the "iso" and "printable_name" columns:
This is only three of the many methods you can use in PHP to manipulate arrays but it gives you a taste of what's there and what's to come in his future articles.
