In this PHP programming course, we take a look at PHP Joining Arrays with Union Operator, How to Join Arrays Using the Union Operator, PHP Join Arrays. In this lesson from Codecademy’s Learn PHP course, section, Associative Arrays, we take a look at the lesson, “Joining Arrays”. In this PHP lesson, we learn that we are able to combine arrays using PHP. We are able to use the union operator ( + ) to combine arrays. We learn that the union operator will take two array operands and then will return a brand new array with all those unique keys from our second array appended to our first array. Learning how to combine arrays in PHP requires only that you practice using the union operator with 2 arrays. As long as you practice combining arrays using the union operator ( + ), then you should begin to learn how to join arrays in PHP. Practicing joining arrays in PHP will help you become a better PHP developer. Make sure to continue learning how to combine arrays in PHP to become the best PHP developer you can be. Learning to code in PHP using associative arrays requires learning array joining syntax. If you get it, then you should be able to master joining arrays in PHP.
