Description: Array functions in PHP are fundamental tools that allow developers to manipulate and manage structured data in the form of lists or collections. These functions operate on arrays, which are data structures that can store multiple values in a single variable. Array functions include a wide range of operations, such as sorting, filtering, searching, merging, and splitting arrays. Their use is essential for efficient programming, as they allow complex tasks to be performed simply and quickly. PHP offers a rich library of array functions, such as `array_merge()`, `array_filter()`, `sort()`, among others, which facilitate data manipulation. These functions not only improve code readability but also optimize performance by reducing the need for manual loops and complex conditions. In summary, array functions are an integral part of the PHP language, providing developers with the necessary tools to work with data effectively and efficiently.
