如何从const字符串名称空间进行转换

Question

Im trying to figure out a way to easily cast a dynamically created object so i can see its properties and exposed methods in my IDE. It seems to be acting weird when the string includes a fully qualified namespace.

Is there anyway I can cast objects from a const string in an abstract class ??

abstract class Models
{
    const MODEL = "foo\\bar\\Model";
}


//OK
    $p1 = "foo\\bar\\Model";
    $p2 = new $p1; 

//FAILS

    //$wannaDoThis = (Models::MODEL) Generator::generate(Models::MODEL);


    //$str1 = Models::MODEL;
    //$str2 = (string) Models::MODEL;
    //$o1 = new Models::MODEL;
    //$o2 = new "".Models::MODEL;
    //$o3 = new (Models::MODEL);

Answer 1

This should work:

<?php

namespace foo\bar;

class Model
{
}

namespace SomeOtherNamespace;

abstract class Models
{
    const MODEL = "foo\\bar\\Model";
}

$class = Models::MODEL;
$x = new $class();
var_dump($x);
