这是之前学习PHP类使用的代码

<?php
class animal{
var $name="1";
var $sex="2";
public static $age;
function setName($name1){
$this->name = $name1;
}

function setSex($sex){
$this->sex = $sex;//sex为对象属性 $sex为局部变量
}

public static function setAge($age){
animal::$age = $age;
}

function getSex($sex){
return $this->sex;
}

}
$tom = new animal ;

//类的静态方法，属性，调用
$tom = new animal();
$tom->name = "json";
//print $tom->name;

$tom->setName("TomSet");
$sex = utf8_encode("男");
$tom->setSex($sex);//名字转码后储存
//print $tom->name;

//$tom ->name = "NewTom";
//print $tom->name;

animal::$age = 22;//静态变量赋值
//print animal::$age;//静态变量取用
animal ::setAge(10);
//print animal::$age;//静态变量取用

$tomJson = json_encode ($tom);
var_dump ($tomJson);
$tom2 = json_decode ($tomJson,true);3.6
var_dump ($tom2);
$newsex = $tom2->getSex();
$newsex = utf8_decode($newsex);
print $newsex;

?>
