Array traversal – PHP

PHP array traversal refers to the process of iterating through each element in an array and performing some operation on it. This can be achieved using various loops like for, foreach, while, or do-while, and array-specific functions like array_walk(), array_map(), and array_filter(). By traversing an array, you can access its elements, manipulate them, or generate a new array based on specific criteria. Array traversal is a fundamental skill for any PHP developer working with arrays.
