Hashtable Class

Anon

Does PHP have something akin to Java's Hashtable class? I created my own implementation of a Hashtable object
with these functions:
function get()
function put()
function keys()
function values()
function sort()
function reset()

The behavior is almost identical to the Java hashtable object functions.

Did I reinvent the wheel?

I've read this:

Arrays. PHP takes arrays and hashtables and merges the two. Any array can act as a standard array, a hashtable, or both. Using this data structure, you can get around Perl's and Java's hashtable limitation of not being able to retrieve the data in a defined order - pull it out either by numeric index or by key name.

Yet...I needed structure similiar to a Java's hashtable in my app. Any comments, suggestions? Would anyone like to see the code for the hashtable object?

I think it's all a matter of preference. PHP's arrays will probably do just about anything the Java Hashtable class will (I'm not that familiar with Java), and I know it's just about the same as Perl's hash data type. There are some lacking features, but they are all workable. It just depends on how you want to go about getting it done. Personally, I don't think a whole new class is needed.

Hey Spencer!

You should share your code in the Shared Code Library if it works.

Before I post it in the shared code library..I'd like some comments and suggestions. Here's the code.. Who's gonna take the first swing? =)

class Hashtable {

var $myHashtable;
var $keys;
var $i = 0;

function Hashtable() {
	return;
}

function get($key) {
	if (isset($this->myHashtable[$key])) {
		$this->reset();
		return $this->myHashtable[$key];
	} else {
		return null;
	}
}
function put($key, $value) {
	$this->myHashtable[$key] = $value;
}
function keys() {
	$i = 0;
	while ($i < count($this->myHashtable)) {
		$keys[] = key($this->myHashtable);
		$i++;
	}
	$this->reset();
	return $keys;
}
function values() {
	$i = 0;
	while ($i < count($this->myHashtable)) {
		$key = key($this->myHashtable);
		$values[] = $this->myHashtable[$key];
		$i++;
	}
	$this->reset();
	return $values;
}
function sort() {
	sort($this->myHashtable);
}
function reset() {
	reset($this->myHashtable);
}

}
