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.

Testing my ZF1 app on PHP 7

Zend Framework 1 is still actively maintained and we fully intend to ensure that ZF1 works with no problems on PHP 7 when its released. Now that PHP 7.0.0 Alpha 1 has been released, it's time to find out if your Zend Framework 1 app works with it. The easiest way to do this is to use a virtual machine. My preference is Vagrant with Rasmus' PHP7dev box. A simple VM I wanted to test… continue reading.

Brent Simmons: How Not to Crash #9: Mindset

Brent Simmons has recently posted How Not to Crash #9: Mindset: I used to think that means I should write code that’s about 80% as clever as I am. Save a little bit for debugging. But over the years I’ve come to think that I should write code that’s about 10% as clever as I am. And I’ve come to believe that true cleverness is in making code so clear and obvious that it looks… continue reading.
