To compliment an existing smorgasbord of arrangements between phpunit,autoload and namespace is this:
I have created a simple test project that runs PhpUnit tests and uses namespace autoloading. I register the autoloading in the bootstrap file like so:
set_include_path(get_include_path() . PATH_SEPARATOR . "/path/to/classes/folder");
spl_autoload_register();
and inside a unit test I load and test my class like so:
$obj = new \some\space\someClass(); // which is in the classes/some/space folder
$this->assertTrue($obj->foo()=='bar');
And I get an error
Fatal error: Class '\some\space\someClass' not found in testSomeClass.php...
While this is not phpunit specific you need to change:
spl_autoload_register();
to
spl_autoload_register('spl_autoload');
Any other component that registers an autoloader unregisters the default __autoload().
If your code has an existing __autoload function then this function must be explicitly registered on the __autoload stack. This is because spl_autoload_register() will effectively replace the engine cache for the __autoload function by either spl_autoload() or spl_autoload_call().
So this is how spl-autoload works together with anything else that uses autoloading.
Make sure your path to classes folder is made relative to script which is run for tests execution. If the script is in subfolder of your projects (for example tests/) then your path should be ../path/to/classes/folder
That's what I have in my tests/bootstrap.php
set_include_path(dirname(__FILE__).'/../classes'.PATH_SEPARATOR.get_include_path());
spl_autoload_extensions('.php');
spl_autoload_register('spl_autoload');

I have defined a puppet function check_value in module test_one
test_one
|- functions
|- check_value.pp
and the function declaration:
test_one::check_value(String $check) >> String {
...
}
I declared a class test_functions within the same module.
test_one
|- functions
|- check_value.pp
|- manifests
|- test_functions.pp
Everything seems to be perfect and I can call this function check_value from the class test_functions within the same module and could fetch the return value.
However, if I call this function from another module, I get Evaluation Error: Unknown function: ...
test_two
|- manifests
|- test_external_function.pp
In the class test_external_function, I tried several ways to call check_value but with no luck:
1. $x = test_one::check_value("t")
2. include test_one
$x = check_value("t")
3. include test_one
$x = test_one::check_value("t")
All trials have failed. Is it possible to call and use these puppet (non-ruby) functions from another module? I couldn't seem to find a way. Google is of no help so far!
As per the puppet documentation, it is possible:
Puppet Functions
Functions are autoloaded and made available to other modules unless those modules specify dependencies. Once a function is written and available (in a module where the autoloader can find it), you can call that function in any Puppet manifest that lists the containing module as a dependency, and also from your main manifest.
This is due to a relatively new requirement introduced in Puppet coding that is documented here. Specifically:
Note that if a module has a list of dependencies in its metadata.json file, it loads custom functions only from those specific dependencies.
Typically, module generation via either the PDK or puppet module generate will create a placeholder metadata.json with puppetlabs/stdlib as a dependency. This is normally fine in practice, but it will break autoloading custom functions from other modules.
In this case (and I guess you would also say in general per best practices), you would want to specify other modules with custom functions you are invoking as dependencies in your metadata.json for the module. For example, in test_two/metadata.json, you could have something like:
"dependencies": [
{ "name": "org_name/test_one", "version_requirement": ">= 1.0.0 < 2.0.0" },
]
with full documentation on specifying dependencies here.
I have studied these 2 sources, but none of those works for me.

Yii2 - How do I AutoLoad a custom class?
I have created custom helper class which I want to include in every model, controller and view in my application. I am using Yii2 advanced app version 2.0.11, IDE I am using is PHPStorm
QUESTION:
What I want to achieve is to not use use keyword at the beggining of every class but still be able to simply call AppHelper::myMethod() in models, controllers and views.
How is that possible?
Closest I got it working was using this solution https://stackoverflow.com/a/35160997/5395463
All other solutions did not work for me. I am getting errors like:
PHP Fatal Error – yii\base\ErrorException
Class 'frontend\controllers\AppHelper' not found
when I simply dont include use commons\commands\AppHelper;
or when not using namespace as they suggest there with other settings:
Fatal error: Uncaught exception 'yii\base\UnknownClassException'
with message 'Unable to find 'common\commands\AppHelper'
in file: C:\xampp\htdocs\domain.com\web\common/commands/AppHelper.php.
Namespace missing?' in ...
SOLUTION:
Thanks for your responses, I got it working finaly. https://stackoverflow.com/a/42330631/5395463 solution works best for me.
So I removed namespace from that class, but left it in common\commands folder, added require to frontend/web/index.php and backend/web/index.php files (not sure if I should add it to yii file in root too, I didnt, so far it is working good anyways), and changed calls of class from AppHelper::myMethod() to \AppHelper::myMethod() looks like eveything is working now.
In Yii2 You can use an explicit way adding \ to full namespaced name
\frontend\controllers\AppHelper
so you can sue your method
\frontend\controllers\AppHelper::yourMethod();
Solution for not lazy coders:
create component with your class so you can use it like \Yii::$app->my_component
if even this is too much and your IDE is better than Windows Notepad prepare macro that will print this for you
Solution for lazy coders:
Save your class in single PHP file without namespace.
Modify you entry script to include this class - i.e. for Basic Project Template it's /web/index.php; add there
require(__DIR__ . '/path/to/MyClass.php');
For Advanced Project Template modify it properly.
Now you can use your class by calling it like \MyClass (yes, \ is required and yes, your IDE probably will modify it anyway to MyClass with use MyClass; added at the beginning.
I am working on on the basic tutorial on using ratchet mentioned here http://socketo.me/docs/push.
I have created a test setup for the tutorial that works flawlessly. However, when I am trying to integrate the setup with CakePHP 3 I am running into problems. The ratchet and ZMQ servers are independent just the way mentioned in the tutorial. Only the following piece of code needs to move into CakePHP 3 controllers:
$context = new ZMQContext();
$socket = $context->getSocket(ZMQ::SOCKET_PUSH, 'my pusher');
$socket->connect("tcp://localhost:5555");
$socket->send(json_encode($entryData));
This code basically submits new data to ZMQ queue for forwarding to ratchet. If I place the same 4 lines in a plain PHP file outside CakePHP 3 codebase it works. When I place the same four lines inside APP\Controller\SamplesController it says the class APP\Controller\ZMQContext not found.
CakePHP 3 docs mention that vendor libraries installed via composer will be automatically available through autoloader. I have installed React\ZMQ library via following command:
php composer require react/zmq
I have tried accessing the class via following namespaces but none of them have worked:
ZMQContext ( Class 'App\Controller\ZMQContext' not found )
\ZMQContext ( Class 'App\Controller\ZMQ' not found )
React\ZMQ\ZMQContext ( Class 'App\Controller\React\ZMQ\ZMQContext' not found )
\React\ZMQ\ZMQContext ( Class 'React\ZMQ\ZMQContext' not found )
Probably missing out on some namespace concept in PHP but my understanding is that if ZMQContext is available in a normal PHP file through global namespace, then it should also be available within CakePHP 3 via \ZMQContext.
I have following questions:
How can I push data to ZMQ Queue within my CakePHP 3 APP ?
APP::path() & APP::classname() seems to work only for classes within the CakePHP 3 application. How to check path for a particular vendor library class ?
How to autoload vendor library classes correctly ? (I do not wish to require/require_once them as it will needed to be done for each controller that wants to publish data via ratchet)
Is the assumption about accessing global namespace via \CLASSNAME wrong ?
My second attempt at accessing vendor library class at \ZMQContext resolved to App\Controller\ZMQ. How is that possible when it should have attempted within root namespace ?
ZMQContext is not part of react/zmq library so does it mean it part of default php bindings for libzmq ?
This was a simple typo problem:
$context = new \ZMQContext();
$socket = $context->getSocket(\ZMQ::SOCKET_PUSH, 'my pusher');
$socket->connect("tcp://localhost:5555");
$socket->send(json_encode($entryData));
The second namespace specification in second line was missing.
I am trying to manage my code in a sample code to learn. I have a sample application whose dir structure is as follow
-Sample
--bootstrap
--app
--class1.php
--class2.php
--class3.php
--config
--public
--resource
--readme
Everything works fine for me, able to autoload the classes and consume all the feature.
Now, I added namespace to my class definition.
namespace Sample\classes;
and my application won't work. In app needs I am trying to add
$obj = new Sample/classes/class1() //no class found
use Sample/classes as Sample
but still class not found error
Any help to consume namespace in this setup will be appreciated.
You need use backslash instead of slash
$obj = new Sample\classes\class1()
1. Compiled Assembly from JSC
I've compiled what is intended to be client-side JavaScript using the JScript compiler (jsc.exe) on the server side in an attempt to make something that can be tested from a unit testing project, and maybe even something that can be debugged on the server side.
The compiled file contains only functions as follows (just for example) and it compiles fine into BitField.exe. Notice, no wrapper class or package in the source code.
------ BEGIN FILE (BitField.js) -------
function BitField(){
this.values = [];
}
// more functions ...
------- END FILE -------
jsc /fast- /out:BitField.exe Bitfield.js
Results in a BitField.exe assembly.
Success! Well, kind of ....
2. Testing Assembly / Access Point?
Secondly I've created a test project (in C#) and referenced in the BitField.exe assembly successfully. (The type of project is irrelevant but I'm providing more description to paint a full picture.)
The problem seems to be: I cannot find the namespace or a point at which I can access the BitField functions inside the BitField.exe assembly from my C# test project. The assembly doesn't seem to be a "normal".
In other words I need in C#
using ???WHAT???
Note: I don't want to use JScript "extensions", meaning keywords that won't run client-side (in a web browser), for example, class, package etc because I want the code to be clean as possible for copy & paste back into client side script environment (Regardless said "clean" code compiles fine by jsc.exe without use of those extensions). When I try to wrap the functions in package and class it starts producing compile errors so that's another reason not to use them - because they appear to make me alter my code.
Any suggestions as to how I can use the functions of the compiled JScript assembly (by having it referenced into another assembly) when there are no explicit containers in it?
Update / Proof
.NET Reflector view
After playing around with it for a while, and trying various combinations of command-line switches for jsc.exe, I'm pretty sure that what you're trying to do won't work as you'd wish it to. If you try to compile a js file that contains functions into a .Net library assembly, you get an error:
BitField.js(1,1) : error JS1234: Only type and package definitions are allowed inside a library
But, there is hope, yet! Here's what I would do...
I would keep your "clean" BitField.js file just as it is, and then create a batch file that wraps it in a JScript class and writes it out to a "dirty" js file. It's pretty clean if you think of it as part of the compilation of the code into the DLL. The code to wrap the BitField.js into BitFieldClass.js would look like this:
merge-into-class.js
var fso = new ActiveXObject("Scripting.FileSystemObject");
var ForReading = 1;
var inputFile = fso.OpenTextFile("BitField.js",ForReading, false);
var outputFile = fso.CreateTextFile("BitFieldClass.js", true);
outputFile.write("class BitFieldClass{\n");
while (!inputFile.AtEndOfStream)
{
var textLine = inputFile.ReadLine();
outputFile.write (textLine + "\n");
}
outputFile.write("}");
outputFile.close();
Then the batch file to wrap it and compile it is really simple:
compile-js.bat
cscript merge-into-class.js
jsc /t:library /out:BitFieldClass.dll bitFieldClass.js
Of course, if you wanted to do multiple files, you'd have to parameterize things a bit, but hopefully this is enough to demonstrate the idea.
