Stacked data organization is useful for creating dynamic functionality. Arrays in PHP, push & pop functions on the first and last elements allow you to organize a recursive stack. Using objects with different functionality, you can get effective solutions.
PHP array_push () adds a new element to the end of the array. The array_pop () function retrieves the last element from an array. This allows you to work with the last element in the context of its functionality.
Syntax and Analogies
The usual operation $ arr [] = 'apple' works like the PHP function array_push ('apple'). The difference between a function and an assignment operation, which creates a new array element: it allows you to add several elements and reports the number of elements in the array after the operation is completed.
Adding elements to an array without specifying a key is more convenient than using a function. There are cases when the array is one-dimensional, but its elements are conveniently considered in pairs, blocks or sets. In fact, when you need to add several elements to an array in PHP at once, array_push is more convenient. Keep this in mind.
The combination in the triad: array push, PHP, and the associative array is not really possible. You cannot specify the desired index here. But PHP rules do not limit the developer. If the left side of the idea: add an element to the stack (array), then the right side of the idea is an abstraction.
Array structure and logic level
In essence, an associative array is a simple combination of key and value. If we consider the array as functionality in the context of its elements, the meaning is transformed to a completely different level.
For the developer, it does not matter how the array is arranged, it is important how to use it. If the key is the sequence: 0, 1, 2, ... - this is a good option. If the keys are the words: 'fruits', 'vegetables', 'cereals', ... - this is another logic of presenting information.
Going to the level of objects as elements of an array makes it possible to turn an array into a logic of interaction of functionalities.
Objects in Arrays
One real object can define an 'apple' and then the object can have different functionality. For the farmer, these are actions to optimize yield, and properties are the quality of the crop. For the merchant, these are delivery times, grades, taste, consumer interests. For the buyer, this is data on the appearance, usefulness of the product, places of purchase.
When it comes not only to one product (object), but to several - it is appropriate to use an array and here PHP array_push () is a simple solution and there is no need for keys. The sequence of placing objects in an array does not matter much.
The farmer “in the cycle” can look over his entire assortment and perform the necessary actions at the right time both for the “apple” object and for everything else: “pear”, “plum”, ... The merchant and the buyer will do the same.
There is a problem, but the solution to this problem is conveniently transferred to the object itself in the application that is relevant in a particular field to achieve a specific goal. Once you add a number of objects to the PHP array_push () function, you can simply use the array, giving the objects the ability to independently implement their functionality.
