利用php制作对战后台程序

<?php
//设置当前页面编码格式
header("Content-type:text/html; charset=gbk");

class hero{
public $name; //名字
public $blood; //血量
public $attack; //攻击力

//放技能的方法
public function jineng(){
$arr = array(
array(50,"隔山打牛"),
array(60,"降龙十八掌"),
array(45,"九阳神功"),
array(20,"葵花宝典"),
array(70,"六脉神剑")
);
$gs = count($arr);

$sy = rand(0,$gs-1);
echo "{$this->name}使用了{$arr[$sy][1]}
";
return $arr[$sy][0];
}

//构造函数
public function __construct($name,$blood,$gjl){
$this->name = $name;
$this->blood = $blood;
$this->attack = $gjl;
}
}


//造第一个人
$h1 = new hero("狗蛋",800,15);

//造第二个人
$h2 = new hero("大壮",700,16);

while(true){

//随机一下，是普攻还是放技能
$sj1 = rand(0,1);
$gj = 0; //本次h1能打掉多少血
echo "{$h1->name}打{$h2->name}
";
if($sj1){
$gj = $h1->jineng();
}else{
$gj = $h1->attack+rand(0,20);
}
$h2->blood = $h2->blood-$gj;
echo "{$h1->name}打掉了{$h2->name}的{$gj}血
";
echo "******************************
";

$sj2 = rand(0,1);
$gj2 = 0; //本次h2能打掉多少血
echo "{$h2->name}打{$h1->name}
";
if($sj2){
$gj2 = $h2->jineng();
}else{
$gj2 = $h2->attack+rand(0,20);
}
$h1->blood = $h1->blood-$gj2;
echo "{$h2->name}打掉了{$h1->name}的{$gj2}血
";
echo "******************************
";

if($h2->blood<=0){
echo "{$h1->name}赢了";
break;
}else if($h1->blood<=0){
echo "{$h2->name}赢了";
break;
}
echo "----


";
//休眠
sleep(3);
}

　　如果页面内只有php代码，只需要写揩油<?php即可，不需要写结尾；

　　sleep()代表休眠时间。
