PHP Array Class
This class is a wrapper for array's that allows you to use oop to create and manage an array
Background
This class is inspired by Java and C#'s array class.
The Code
If you'd like to use oop to manage an array this class is meant to provide a data type of sorts for that effort.
PHP Code:
<?php
class Table
{
private $type, $table, $DEFAULT_KEY;
public function __construct($val = "number")
{
$this->table = array();
$this->DEFAULT_KEY = "item";
$val = strtolower($val);
switch($val)
{
case "number":
$this->type = "number";
break;
case "mixed":
$this->type = "mixed";
break;
default:
$this->type = "number";
break;
}
}
public function add($val, $key = null)
{
if($this->type == "number")
{
$this->table[] = $val;
}
else
{

{

}
else
