This article explains the static attributes and static methods in PHP with examples. Share it with everyone for your reference. The details are as follows:

<&#63;php
/*
 * static
 */
 /*静态：属于类而不属于单个对象 （全局的，所有对象共享的）
 *静态属性：类的方法内调用静态属性时，不要使用$this->方式，而要使用self::的方式
 *静态方法：
 *在类没有任何对象的时候也能被调用
 *当成普通方法来用也没问题的
 *在静态方法中不能调用普通方法
 * 
 * */
 class xin {
  static private $name;
  public function setname($namec) {
    self::$name = $namec;
  }
  public function getname() {
    return self::$name;
  }
  static public function name($namecc) {
    echo "I am $namecc";
  }
 }
 $xind = new xin();
 $xind->setname("地方 <br/>");
 echo $xind->getname();
 $oldd = new xin();
 $oldd->setname("政府 <br/>");
 echo $oldd->getname();
 echo $xind->getname();
 echo xin::name("星星");
