Using abstract factories with Slim 3

In my Slim 3 skeleton, I chose to put each action into its own class so that its dependencies are injected into the constructor. We then register each action with the DI Container like this: $container['App\Action\HomeAction'] = function ($c) { return new App\Action\HomeAction($c['view'], $c['logger']); }; In this case, HomeAction requires a view and a logger in order to operate. This is quite clear and easy. However, it requires you manually register each action class with… continue reading.

Zend\Input fallback value

Recently an issue was reported against Zend\InputFilter where the reporter has discovered a regression where the fallback value wasn't being populated correctly. Matthew investigated, fixed it and asked me to review it. I was fascinated as I didn't realise (or had completely forgotten!) that Zend\Input and Zend\InputFilter supported fallback values so I looked into it and it turns out that it's simple and works exactly as its name implies. For the basic case of using… continue reading.

Zend\Input and empty values

I'm forever getting confused about how the combination of Zend\Input's required, allow_empty & continue_if_empty interact with an empty value, so I've decided to write it down. These settings define what happens when you try to validate an empty value for a given input. For Zend\Input, empty means exactly equal to null, an empty string or an empty array. Firstly, let's start with the three settings: Setting Default What it does required true When true, the… continue reading.

Checking your code for PSR-2

Most of the projects that I work on follow the PSR-2 coding style guidelines. I prefer to ensure that my PRs pass before Travis or Jenkins tells me, so let's look at how to run PSR-2 checks locally. PHP_CodeSniffer My preferred tool for checking coding styles in PHP is PHP_CodeSniffer. This is command line tool, phpcs, that you can run against any file. PHP_CodeSniffer can test against a number of standards. The default is PEAR,… continue reading.

Custom OAuth2 authentication in Apiiglity

I have a client that's writing an Apigility API that needs to talk to a database that's already in place. This also includes the users table that is to be used with Apigility's OAuth2 authentication. Getting Apigility's OAuth2 integration to talk to a specific table name is quite easy. Simply add this config: 'storage_settings' => array( 'user_table' => 'user', ), To the relevant adapter within zf-mvc-auth => authentication config. However, if you want to use… continue reading.

Replacing Pimple in a Slim 3 application

One feature of Slim 3 is that the DI container is loosely coupled to the core framework. This is done in two ways: The App composes the container instance rather than extending from it. Internally, App depends on the container implementing the container-interop interface. You can see this decoupling in the way that you instantiate a Slim 3 application: $settings = []; $container = new Slim\Container($settings); $app = new Slim\App($container); Slim 3 ships with Pimple… continue reading.

Debugging PHP SOAP over SSL using Charles

I'm currently integrating against a SOAP server using PHP which wasn't working as I expected, so I wanted to find out what was happening over the wire. I have Charles installed and use it regularly with OS X's system-wide proxy settings. However, PHP's SoapClient doesn't use these, so I had to work out how to do it manually. Enabling SoapClient to send via a proxy is really easy and is documented by Lorna Mitchell in… continue reading.

First beta of Slim Framework 3

Last night, I tagged beta 1 of Slim Framework 3! This is a significant upgrade to v2 with a number of changes that you can read on the Slim blog. For me, the two key features that I'm most excited about are: PSR-7 support, along with the standard middleware signature of: function($request, $response, $next) { return $response; } Dependency injection container with container-interop compliance. We ship with Pimple by default, but I'm planning to use… continue reading.

Selecting the service port with PHP's SoapClient

I'm currently integrating with a SOAP service which has two different services defined. The relevant part of the WSDL is: <wsdl:service name="Config"> <wsdl:port name="BasicHttpBinding_IConfiguration" binding="tns:BasicHttpBinding_IConfiguration"> <soap:address location="http://nonsecure.example.com/Configuration.svc"/> </wsdl:port> <wsdl:port name="BasicHttpsBinding_IConfiguration" binding="tns:BasicHttpsBinding_IConfiguration"> <soap:address location="https://secure.example.com/Configuration.svc"/> </wsdl:port> </wsdl:service> I discovered that PHP's SoapClient will select the first port it encounters and doesn't provide a way to select another one. This was a nuisance as I wanted to use the SSL one. Through research, I discovered that I can… continue reading.

Accessing services in Slim 3

One of the changes between Slim Framework 2 and 3 is that the application singleton has gone. In Slim 2, you could do this: $app = \Slim\Slim::getInstance(); // do something with $app In general, you didn't need access to $app itself, but rather you wanted access to something that the app knows about, such as a database adapter, or the router for access to the urlFor method to create a URL to a route. With… continue reading.
