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;

?>
