Optimizing PHP performance by using fully-qualified function calls

Today, a little conversation on Twitter escalated rather quickly. Apparently PHP runs function calls differently depending on namespaced or non namespaced context. When calling functions in a namespaced context, additional actions are triggered in PHP which result in slower execution. In this article, I'll explain what happens and how you can speed up your application.

Writing your first NodeJS Lambda function

Last week I was playing around with writing some custom Slack slashcommands and cronjobs. Originally, I started writing these integrations with PHP. Since slack requires a publically available endpoint and I did not want to set up a server for these scripts, I decided to take a look at AWS Lambda. This Amazon service makes it possible to run scripts serverless. The scripts are triggered based on triggers inside of AWS. In this artile you can find out how to get started with writing lambda functions.

GrumPHP approves Bitbucket Pipelines!

Today, my invitation for Bitbucket Pipelines Beta got accepted! For those who haven't heard about it: Pipelines is a Continuous Delivery tool integrated in Bitbucket. When you push your changes to your Bitbucket repository, it will spin up a Docker container and run the actions you specify. I was quite exited about the concept and immediately started to set up an automated test scenario with GrumPHP.

Authenticating with X.509 client certificates

Last week, I was diving in different authentication systems for API's. One of the better ways of authentication is through X.509 client certificates.

Hijacking your code with streams

Lately, you might have noticed that streams are getting more important in the PHP scene. They are for example widely used in PSR-7 and implemented in Diactoros. Yesterday I was scrolling down the issues list of phpspec and bumped in on a pull request. This pull request shows that it is possible to convert code in-memory and later require the modified content to be executed. Wow, that is awesome! Let's take a look at it.

Replacing service dependencies with proxies

When using the Zend Framework 2 service manager, it is possible to create shared services that will be loaded only once. In some situations however, it is very hard to switch the already injected dependencies in this service. You could mark the service as unshared even if this is often unnecessary. Another solution is to wrap the service with a proxy object and use the proxy instead of the service.

Generating ZF2 template maps on the fly

One of the performance boosters in Zend Framework 2 is using template_map instead of template_path_stack in the view manager. While developing, it is easier to use the stack. This is because you don't have to add a mapping every time you create a new view. At the end of the development you might forget to transform the stack into a template map. This is why it is useful to never use the stack and automate the generation of the template_map array instead.

Three-way data binding in AngularJS

One of the cool features in AngularJS is the two-way data binding. When you change a property of an object, the value is instantly changed in every view or service that is using this property. A while ago, I saw a video about the combination of AngularJS and Firebase. This combination makes it possible to create three-way data binding in AngularJS.
