Here we have used array() function to create array. Exampleįollowing is the example showing how to create and access numeric arrays. These arrays can store numbers, strings and any object but their index will be represented by numbers. NOTE − Built-in array functions is given in function reference PHP Array Functions Numeric Array Multidimensional array − An array containing one or more arrays and values are accessed using multiple indices This stores element values in association with key values rather than in a strict linear index order. Values are stored and accessed in linear fashion.Īssociative array − An array with strings as index. Numeric array − An array with a numeric index.
