An array is a named range that is used to store a series of variable values.
Each array element has an associated index (also a keyword) that can be used to access elements.
PHP allows you to use numbers or strings evenly

1, the creation of the array
Copy Code code as follows:
var arrayobj = new Array (); Create an array
var arrayobj = new Array ([size]); Create an array and specify the length, note not the upper limit, is the length

Defined:
Each entity of an array contains two items: key and value, which can be retrieved by a query key. These keys can be numeric (numerical) or associated (associative)
