魔法get方法有问题
问题描述：
I am trying to write my own magic __get method in php. But am getting this error: __get() must take exactly 1 argument. The error is referring to the last line in the function below.
Any idea's?
public function __get()
{
$method = 'get'.ucfirst($name);
if(!method_exists($this, $method))
throw new Exception('Invalid property');
var_dump($method);
return $this->{$method}();
}
我正在尝试在php中编写自己的魔法__get方法。 但是我收到此错误： __get（） 必须正好用1个参数。 错误是指下面函数的最后一行。 p>
有什么想法吗？ p>
公共函数 __get（）
{
$ method ='get'.ucfirst（$ name）;
if（！method_exists（$ this，$ method））
throw new Exception（'Invalid property'）;
var_dump （$ method）;
返回$ this-＆gt; {$ method}（）;
}

答
you must specify a parameter that refers to the variable name you are trying to access.
答
Pass in $name:
public function __get($name)
答
Is this better?
public function __get($name)
{
$method = 'get'.ucfirst($name);
if(!method_exists($this, $method))
throw new Exception('Invalid property');
var_dump($method);
return $this->{$method}();
}
I added the name argument.
答
The magic get function required exactly one argument, like the error said. Please try the following code:
public function __get( $name )
答
one argument is missing in __get($name) function. Which will give you the value of required variable.
public function __get($name) {
...
...
}
