Data structure, ---: Data structure --- Linear table learning (php simulation): Linear table: a limited sequence of zero or more data elements (note: the following are all integer data simulations) a sequential storage structure (Use a storage unit with a continuous address to store the data elements of the linear table at a time) 1.1 Three attributes: the starting position of the storage space; the maximum storage capacity; the current length Note: The array length is the length of the storage space that stores the linear table (usually unchanged), but the language can dynamically increase capacity, which will cause performance losses; The length of the linear table is the number of data elements; The linear table starts counting from 1, so for
