array
Description
Create an array
Syntax
array ( [ mixed $... ] ) : array
Parameters
...Syntax "index => values", separated by commas, define index and values. index may be of type string or integer. When index is omitted, an integer index is automatically generated, starting at 0. If index is an integer, next generated index will be the biggest integer index + 1. Note that when two identical index are defined, the last overwrite the first. Having a trailing comma after the last defined array entry, while unusual, is a valid syntax.
Return
