PHP在类的静态方法中调用函数

Question

class MainClass {

    public static function myStaticMethod(){
        return myFunction();

        function myFunction(){
            echo 'hello';
        }
    }
}

The above code when executed returns call to undefined function myFunction();

Please, any ideas on how to call the function within the method?

Thank you

Move the function deceleration to before you attempt to use it when defining functions within other functions...

class MainClass
{
  public static function myStaticMethod()
  {
    function myFunction()
    {
      echo 'hello';
    }
    return myFunction();
  }
}

MainClass::myStaticMethod(); // No error thrown

Note that repeat calls to MainClass::myStaticMethod will raise Cannot redeclare myFunction() unless you manage that.

Otherwise, move it outside of your class

function myFunction()
{
  echo 'hello';
}

class MainClass
{
  public static function myStaticMethod()
  {
    return myFunction();
  }
}
