For the associative array, the format is <serialised key> ; <serialised value>, repeated for each association/pair in the array.
Even when using numerical indexes, PHP internally stores arrays as associative arrays. [13] So, PHP can have non-consecutively numerically indexed arrays. The keys have to be of integer (floating point numbers are truncated to integer) or string type, while values can be of arbitrary types, including other arrays and objects.
In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert ...
A keyspace (or key space) in a NoSQL data store is an object that holds together all column families of a design. [1] [2] It is the outermost grouping of the data in the data store. [3] It resembles the schema concept in Relational database management systems. [4] Generally, there is one keyspace per application.
A tabular data card proposed for Babbage's Analytical Engine showing a key–value pair, in this instance a number and its base-ten logarithm. A key–value database, or key–value store, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, and a data structure more commonly known today as a dictionary or hash table.
