The function `array_push()` in PHP is designed specifically to add one or more elements to the end of an array. When you call this function, you provide the array as the first argument, followed by the elements you wish to add. The function modifies the original array directly and also returns the new total number of elements in the array after the additions.

This behavior is crucial for developers who are managing lists and queues, as it allows them to easily append elements without needing to manually determine the next available index. By using `array_push()`, it's straightforward to build dynamic arrays where new items can be added as they become available, making it a fundamental function in PHP for array manipulation.
