A PHP Library that implements Java's Hashmap

HashMaps

HashMaps is a custom PHP Library that allows support for Java HashMaps in PHP.

Usage

use HashMap\HashMap;

require "HashMap.php";

$map = new HashMap("String", "String");

when constructing new HashMap(), you're passing two arguments.

The first argument is the expected type of the Key, this either be String, Integer or Float not case-sensitive

The second argument you pass is the expected type of the Value, you can see them in a table below

Type	Name	Alias
string	String	Str
float	Float	-
int	Integer	Int
array	Array	-
callable	Callable	Function
resource	Resource	Res
null	Null	-
bool	Bool	Boolean
object	Object	Obj
double	Double	-
long	Long	-

=> To add custom classes (or objects) you gotta use Classname::class, e.g.: Socket::class

Not case-sensitive
