In this Learn PHP programming tutorial we take a look at Learning PHP, Ordered Arrays Review, Understanding PHP Ordered Arrays, and we Review PHP Ordered Arrays. This video is based on the last lesson in Codecademy’s Learn PHP, Ordered Arrays section. In it we go over all the different concepts we learned about Ordered Arrays in PHP. We go over the fact that arrays are a collection of ordered data, and are a type of data structure that are computer science fundamentals! The location of a value, or element, in an array is called its index. All the elements in an ordered array are arranged in ascending order starting with index 0, then the second value in the array is at index 1, and so on. We are able to create arrays using PHP built-in function array(). We are also able to use short array syntax using square brackets. If any of this is sounding strange to you, make sure to go back and watch our previous lessons to make sure you understand ordered arrays in PHP. Practice using ordered arrays and make sure you are understanding ordered arrays before moving on. Learn to create ordered arrays using long and short syntax just in case you run into one way or the other. Review ordered arrays and practice what we learned!
