An associative array, also called a TAS, is a type of data structure that maps keys to values. These arrays are commonly used to store frequently accessed information. In PHP, for example, you can create a TAS and assign different values ​​to specific keys, such as “color,” “size,” or “price.” Then, you can retrieve a value by referring to its key. For example, if you want to find the color of a product, you can access this information using the “color” key in the TAS. Depending on the retrieved value, you can then perform specific actions, such as displaying a message indicating the product’s color.
