本文实例讲述了php单例模式实现方法。分享给大家供大家参考。具体如下：

<?php
/**
 * @copyright 2013 maguowei.com
 * @author Ma Guowei <imaguowei@gmail.com>
 */
/**
 * 单例模式
 * Class Single
 */
class Single
{
  private $name;
  private static $single;
  private function __construct()
  {
  }
  public static function init()
  {
    if(empty(self::$single))
    {
      self::$single = new Single();
    }
    return self::$single;
  }
  public function getName()
  {
    return $this->name;
  }
  public function setName($name)
  {
    $this->name = $name;
  }
}
$s = Single::init();
$s->setName('hhhh');
echo '$s:'.$s->getName();
unset($s);
$m = Single::init();
echo '$m:'.$m->getName();

希望本文所述对大家的php程序设计有所帮助。
