将可变长度参数列表传递给父级 [英] Passing Variable Length Argument List to Parent
问题描述
你好!
我有一个类方法,它采用可变数量的参数和
正确处理它们使用func_get_args等...
ie
class ABC
{
公共功能MooSaysTheCow()
{
foreach(func_get_args()as $ arg_name => $ arg_value)
{
...
}
}
}
现在,问题是:我想覆盖这个类和这个方法,有
,重写方法调用基类,然后做其他事情。
问题是我不知道如何传递参数。
class DEF
{
公共功能MooSaysTheCow()
{
父母:: MooSaysTheCow(我在这里放什么?????);
echo带有令人兴奋的新功能的被覆盖版本!;
}
}
有什么想法吗?
迄今为止我想到的最好的是非常令人讨厌的,并且不灵活
任意数量的参数.... blech。

class DEF
{
公共函数MooSaysTheCow()
{
switch(func_get_num_args( ))
{
案例1:
父:: MooSaysTheCow(func_get_arg(0));
休息;
案例2:
父:: MooSaysTheCow(func_get_arg(0),func_get_arg(1));
休息;
等....
...
..
arg_name =>
{
...
}
}

hello!
I have a class method that takes a variable number of parameters and
correctly deals with them with func_get_args, etc ...
i.e.
class ABC
{
public function MooSaysTheCow()
{
foreach (func_get_args() as $arg_name => $arg_value)
{
...
}
}
}
now, the problem is: i want to override this class and this method, have
that overriding method call the base class and then do something else. The
problem is that I don''t know how to pass the parameters along.
class DEF
{
public function MooSaysTheCow()
{
parent::MooSaysTheCow( WHAT DO I PUT HERE ????? );
echo "Overridden version with new exciting features!";
}
}
Any ideas?
the best i''ve thought of so far is terribly yucky, and not flexible to
arbitrary numbers of parameters .... blech.
class DEF
{
public function MooSaysTheCow()
{
switch (func_get_num_args())
{
case 1:
parent::MooSaysTheCow(func_get_arg(0));
break;
case 2:
parent::MooSaysTheCow(func_get_arg(0), func_get_arg(1));
break;
etc ....
