Dr. Frank Benford discovered that in many cases, the number 1 is the first digit about 30,1% of the time. For example, most numbers in a set (about 30,1%) will have a leading digit of 1. This is followed by about 17.6% starting with a number 2 and each subsequent numeral, 3 through 9, will be the leading digit with decreasing as seen in the image.

Testing Benford’s Law in Symfony Framework

In the traditional Symfony web application we want to find out how often “1” to be the first digit of the total line-numbers for each PHP file. We want to do same for each…

The Internationalized Resource Identifier is defined similarly to a URI, but the character set is extended to the Universal Coded Character Set. URIs are the glue that binds the Web together. IRIs extend and strengthen the glue, by allowing people to identify Web resources in their own language.

While URIs are limited to a subset of the ASCII character set, IRIs may additionally contain most characters from the Universal Character Set (Unicode/ISO 10646)[4][5], including Chinese, Japanese, Korean, and Cyrillic characters.

— Fabien Potencier (Symfony’nin kurucusu), SymfonyCon 2017

API Platformu, API odaklı projelere adanmış güçlü ama kullanımı kolay bir full stack framework’tür. Sektör lideri standartları (JSON-LD ve Hydra, GraphQL, OpenAPI …) destekleyen tam özellikli API’ler oluşturmak için bir PHP kütüphanesi içerir, bu API’ları bir çırpıda (admin, PWA ve mobil uygulama oluşturucu, hypermedia client…) ve anında bulutta geliştirmek ve deploy için güzel bir Docker ve Kubernetes entegrasyonu ile birlikte gönderilir.

Başlamanın en kolay ve güçlü yolu API Platformu dağıtımını indirmektir. API Platformu şunları içerir:
