php接口的使用实例函数
interface Ren1
{const XINGMING="张三";
function shuohua1();
function shuohua2();}
interface Ren2 extends Ren1
{function shuohua3();
function shuohua4();}
interface Ren3
{function shuohua5();}
interface Ren4
{function shuohua6();}
class Ren5
{function shuohua7()
{echo "7777
";}}
class Ren extends Ren5 implements Ren2,Ren3,Ren4
{function shuohua1()
{echo "1111
";}
function shuohua2()
{echo "2222
";}
function shuohua3()
{echo "3333
