Application sample code for Arrayobject extension

Zend_config is very easy to use, I prefer its array form, in fact, Arrayobject can do the same thing <?php $config = Array ( ' DB ' => array ( ' Adapter ' => ' MySQL ', ' Config ' => array ( ' Host ' => ' localhost ', ' Port ' => ' 3306 ', ' dbname ' => ' mydbname ', ' username ' => ' dbuser ', ' Password ' => ' Dbpassword ', ' CharSet ' => ' UTF8 ', ' Prefix ' => ', ), ), ); $config = new Zend_config ($config); echo $config->db->adapter; foreach ($config->db->config as $k => $v) { echo "$k | $v \ n "; } echo count ($config); //... And even more ways The following extensions, through a few magic methods, can not only achieve what zend_config can do, but also inherit array_object all available methods <?php /** * Converts an array to a pair-like shape using * * @package Core * @author Akon (tomato red) <aultoale@gmail.com> * @copyright Copyright (c) 2008 (http://www.tblog.com.cn) * @license http://www.gnu.org/licenses/gpl.html GPL 2 */ Class Extend_arrayobject extends Arrayobject { /** * Construction Method * * @param array $array */ Public function __construct (array $array = Array ()) { foreach ($array as & $value) Is_array ($value) && $value = new self ($value); Parent::__construct ($array); } /** * Get value by specifying name using magic method * * @param string $index * @return Mixed */ Public Function __get ($index) { return $this->offsetget ($index); } /** * Use magic method to modify the value of the specified name * * @param string $index * @param mixed $value */ Public Function __set ($index, $value) { $this->offsetset ($index, $value); } /** * By magic method to determine whether the data has been set * * @param string $index * @return Boolean */ Public Function __isset ($index) { return $this->offsetexists ($index); } /** * Remove data by magic method * * @param string $index */ Public Function __unset ($index) { $this->offsetunset ($index); } /** * Transform data information into arrays * * @return Array */ Public Function ToArray () { $array = $this->getarraycopy (); foreach ($array as & $value) ($value instanceof self) && $value = $value->toarray (); return $array; } /** * Convert data Group to string form * * @return Array */ Public Function __tostring () { Return Var_export ($this->toarray (), true); } }
