In php, arrays can be defined in several ways, such as array () or arr, next I will give you a detailed introduction of various techniques for defining php arrays. In php, array definition has several methods, such as array () or arr [], to

PHP does not need to specify its size when creating an array. Because PHP is a loosely typed language, it doesn't even need to be declared before using arrays. Although there are no strict restrictions, PHP provides a formal and informal array

An array is a collection of ordered data. Elements in an array may not belong to the same data type. Using a uniform array name and subscript to uniquely determine an element in an array, changing one of the elements does not affect other elements.

An array is a set of data that has the same data type. Java supports multiple arrays, each base cell of a one-dimensional array is data of the basic data type, and the two-dimensional array is a one-dimensional array of one-dimensional arrays, and
