In Zend, inside the "Library" folder, I have a PHP file that I want to include in another file. How do I do that?! I cannot figure out the root to the library folder.
How about study some documentation about Zend autoloading capabilities. There are plenty of options, how to autoload files,which contains php classes.
here you go http://framework.zend.com/manual/en/zend.loader.html
But if you want it plain and simple :
every zend application generated with zf tool should have defined APPLICATION_PATH constant, which is pointing into application folder. So you could use it for constructing absolute path to file
define namespace inside config, e.g. Autoloadernamespace[] = 'Custom_'. Then if you create inside library class file ./library/Custom/Object.php with class Custom_Object, Zend loader loads this file when you will be creating instance of Custom_Object class (or call static method)
RTFM, there are other things possible ...

As far as I know, namespace is used for preventing class, function, ... collision in PHP. In Laravel 8 when we create a model for example, the name space is App\Models and when we want to use this model, we have to use it like use App\Models\MyModel. My question is when we use use Illuminate\Support\Arr, why we don't use the full path explicitly vendor\laravel\framework\......
It’s part of the PSR-4 auto loading standard which replaces the PSR-0 auto loading standard. Composer compiled an autoload.php from your project’s and dependencies’ composer.json. As part of the bootstrapping process that file is included in the application and registers each namespace.
I am using the Laravel 4 framework, and I am trying to set up the Facebook authentication system. I have an authentication system I had set up on another site (not using a framework) that used a config.php and process_facebook.php file. I am trying to implement this config.php file into my views. So far, I am including the files in a folder called "includes", within my "app" folder. I am trying to use the following code to implement it:
$app = app();
include($app['path.app'].'/includes/config.php');
My question is, where in the view do I put this code? Do I have to use php tags? (I am using the blad functionality). Your help is appreciated.
Laravel is an MVC framework, the purpose is to organise your code and clean your views. So this shouldn't be in your view.
I think the best way should be :
Create a facebook.php file in the config folder wich contains all your facebook configuration (read http://laravel.com/docs/configuration)
Create a folder named services, helpers or includes (as you want) and put process_facebook.php inside (I bet it contains the methods to deal with facebook API).
Add two lines of configuration to include this new folder
Like that :
// composer.json
"autoload": {
"classmap": [
[...]
"app/services",
]
},
// start/global.php
ClassLoader::addDirectories(array(
[...]
app_path().'/services',
));
Then, you can use your facebook class or methods all over your app.
The route you are taking to include configuration files is not recommended, but it is possible. Please see information about Laravel Configuration Files.
You should be able to use the following in your view:
<?php include(app_path().'/includes/config.php'); ?>
As it is a configuration file, it would be better to use require() instead of include().
In addition, it would also be better to include the file in the necessary controller(s).
This is probably a stupid question, but I'm new to Ruby on Rails and I could use a little guidance. I want to have a helper/utility class that performs a group of network operations and returns results. Where do I put that class and how do I use it.
I've created network_helper.rb in my app/modulename/helpers directory. In my controller when I try to do
myNetworkHelper = ModuleName::NetworkHelper.new
results = myNetworkHelper.getResults
I get an error
undefined method `new' for MyModule::NetworkHelper:Module
I'm sure this is just a misunderstanding of how ruby on rails works. Can I get some clarification?
Would it be better to make this a class instead of a module and put it in libs? And can I add subfolders in libs and have them automatically loaded?
Lib or Classes
Little utility classes like this typically go in the lib folder, though some people prefer to create a folder called classes. Whichever you choose, make sure you import the folder in config/application.rb, as the lib folder is not autoloaded:
config.autoload_paths += %W(#{config.root}/lib)
Concerns
If instead of a utility class, you want to extend some of your models with reusable code, you may also wish to look at the new Rails 4 concerns folders which encourage you to extract reusable modules:
see: How to use concerns in Rails 4
To use new, the thing your calling it on must be a class, not a module. You're using a module. Change module to class in lib/utilities/network_utility.rb.
I cannot verify this at the moment, however I believe one place you can store your custom modules and classes is the lib directory. Alternatively, you should be able to store them in the app directory in the manner you have indicated by adding the following line to your environment.rb:
config.load_paths << File.join(Rails.root, "app", "modulename")
Also, check out Yehuda Katz's answer, which I think not only answers your question better, but also contains some very interesting and useful information and concepts relating to your situation. Hope that helps!
Add your class to app/lib folder instead of lib, so that you don't change autoload paths!
Explanations:
The accepted answer suggests adding the classes to lib.
But according to this discussion:
The lib folder does not belong to the autoload paths since Rails 3.
So it's discouraged to add lib under autoload path. Use app/lib instead.
I'm building my own base to use on multiple sites that I will be building. And I've made a package for that. But I want to extend the CI helpers in that package (not in the app) - helpers such as url_helper, html_helper etc.
I've put a config folder (although I don't really understant what it does) in the package folder and a config file in it (so structure is packages/app_package/config/config.php).
I've put the $config['subclass_prefix'] = 'app_'; (different from the application one preferably) and still not loading the helpers app_url_helper etc
Did anybody do that?
Have a look at CodeIgniter Helpers. Specifically the section labelled "Extending" Helpers.
I'm not quite sure what you mean by:
I've put a config folder (although I don't really understant what it
does) in the package folder and a config file in it (so structure is
packages/app_package/config/config.php).
You're not required to 'create' any config folders or files at all. The config file already exists and is located in application/config/config.php of your CodeIgniter project. The Class Extension Prefix is located ~ line 110 (version dependent). Set it to _app
Now create app_url_helper.php and app_html_helper.php in application/helpers and away you go.
I have the following folder structure:
/main
/loader.php
/build.xml
/components
/package1
/class1.php
/package2
/class2.php
/tests
/package1
/class1.test.php
/package2
/class2.test.php
When I run the web application I load loader.php at first and include other components by calling Loader::load( 'package_name' ). Then all neccessary files are included. The good thing here is that I don't need to include loader.php within the class files because I can rely on having a working instance of Loader.
The Unit Test classes simulate this behaviour by including all neccessary classes explicitly. So there is also no problem with phing and PHPUnit.
But now I want to generate a coverage report with phing and Xdebug. The problem here is that phing seems to load every single PHP file to create the coverage database. Unfortunately it stops because it cannot find the Loader class that is used in the PHP files.
I could easily add an include statement to every class file, but I wonder whether there is a way to include files only if code coverage analysis is inspecting the file?
Other idea: I could also configure the coverage analysis in a way that it scans the unit tests directory and therefore finds all neccessary includes. Then I'd need to filter classes that match to a pattern like /Test$/i or so. Possible?
I looked for ages for something similar.
In the end I ended up with the changes below. Basically you tell php cli to prepend a php file which contains your loading logic.
In php.ini of my cli I've set the following:
auto_prepend_file = autoload.php
I made sure that the file was on my include path (/usr/share/php in my case) and put following lines in it (I use Zend Framework which is also on my include path):
require_once "Zend/Loader/Autoloader.php";
$autoloader = Zend_Loader_Autoloader::getInstance();
$autoloader->registerNamespace('Model_');
Now, what you could do is define your __autoload function and define what needs to be autoloaded, but you get the idea.
It's an ugly hack, but it got things done for me.
