Cannot Call Static Methods of External Classes [$10]

[AKermodeBear]

Hello,

Zephir allows us to create objects that are not currently defined in the project like so:

let someObject = new \Class_From_Elsewhere();

However we cannot call static methods as might be expected:

let someResult = \Class_From_Elsewhere::someMethod("foo");

I'm currently using this as a workaround:

let someResult = call_user_func_array(
   ["\Class_From_Elsewhere", "someMethod"], ["foo"]);

Thank you, Zephir people!

Using Zephir at commit 416c989 (Wed Apr 22).

Alternatively: \Class_From_Elsewhere::{"someMethod"}("foo"); should work

I think warning was caused by \Class_From_Elsewhere does not exist
You need to use prototype with autoload for it class

Can you show full compiler exception?

Howdy,

The compiler will produce an error like this:

Zephir\CompilerException: Class name: MyClass does not exist in /home/bear/repos/zephir-sandbox/test/test/Test.zep on line 6

          return \MyClass::method();
        ---------------------------^

Maybe this one will help you.

namespace Utils;

class SomeClass {
     public function getClassName()
     {
        var className = "NotExists";
        return {className}::method();
     }
}

#!/usr/bin/env php
<?php

class NotExists
{
    public static function method()
    {
        return "Hello from big Hangout";
    }
}


$a = new \Utils\SomeClass(); 
var_dump($a->getClassName());

I am having the same problem. Neither of the workarounds work for me.

\Class_From_Elsewhere::{"someMethod"}("foo"); throws a compiler error and the call_user_func_array workaround just throws a class ... not found error during runtime.

@fabiante To achieve better performance consider use create_instance_params and avoid call_user_func_array as long as you can.

We figured out, that this works, as long as double backslashes are used:

let someResult = call_user_func_array(
   ["\\MyNamespace\\Subnamespace\\MyNormalClass", "someMethod"], ["foo"]);

@sergeyklay Thanks
