从调用对象数组变量静态方法 [英] Calling static method from object array variable

问题描述

在PHP中可以调用类的从一个对象实例静态方法（它包含在数组）是这样的：

In PHP you can call a class's static method from an object instance (which is contained in an array) like this:

$myArray['instanceOfMyClass']::staticMethod(); // works

但由于某些原因，当我使用 $这种变量，我得到一个解析错误。例如：

But for some reason when I use the $this variable, I get a parsing error. E.g:

$this->myArray['instanceOfMyClass']::staticMethod(); // PARSING ERROR

只是为了说明我的意思：

Just to illustrate what I mean:

class MyClass{
    public static function staticMethod(){ echo "staticMethod called\n"; }
}

$myArray = array();
$myArray['instanceOfMyClass'] = new MyClass;
$myArray['instanceOfMyClass']::staticMethod(); // works

class RunCode
{
    private $myArray;

    public function __construct(){
        $this->myArray = array();
        $this->myArray['instanceOfMyClass'] = new MyClass;
        $this->myArray['instanceOfMyClass']::staticMethod(); // PARSING ERROR
    }
}

new RunCode;

如何解决这个任何想法？

Any ideas on how to get around this?

推荐答案

您实际上可以用 - >调用静态方法：

You actually can use "->" to call static method:

$this->myArray['instanceOfMyClass']->staticMethod();
