在php中while(list($key,$val)=each($result)) 是就读取$result数组值并循环获取数组内容赋值给$key,$val哦。

 代码如下 复制代码


echo "类CAR中的所有方法名为:";

echo "

";

$result=get_class_methods("CAR"); //获取类CAR中的方法名get_class_methods()

while(list($key,$val)=each($result))   //循环获取数组内容

{

  echo "方法$key=>$val";

  echo "

";

}

list() 函数用数组中的元素为一组变量赋值。

注意,与 array() 类似,list() 实际上是一种语言结构,不是函数
