Production to dev migration – mydumper, GDPR anonymisation, DDEV automation hooks
Copying a production database to a development environment without a proper process is either a GDPR violation or a security incident waiting to happen. I show a complete pipeline: fast dump with mydumper, automatic anonymisation of personal data, and DDEV hooks that make the sanitised database available to the whole team with a single command.

PHP Fibers deep dive – own scheduler, cooperative multitasking, parallel HTTP requests
PHP 8.1 introduced Fibers as a foundation for cooperative multitasking. Most developers use them only indirectly through ReactPHP or Amp. But understanding Fibers at the mechanism level unlocks the ability to build your own concurrency primitives. I show how Fibers work, implement a minimal cooperative scheduler, and use it to run parallel HTTP requests without a framework dependency.

GraphQL batch loading – BatchServiceContractResolverInterface, cache tags, N+1 fix
The N+1 problem is especially acute in GraphQL because resolvers compose independently without awareness of each other. A query for 20 products that each have categories will trigger 20 separate category queries without batching. Magento 2’s BatchServiceContractResolverInterface and the DataLoader pattern solve this. I show both approaches with cache tag integration.

PHP 8.5 RFC confirmed – pipe operator, readonly inheritance, array_first/last
The PHP 8.5 RFC vote on the pipe operator passed. After years of debate it is officially coming in November 2025. Readonly property inheritance also passed – child classes can now override parent readonly properties in specific cases. array_first() and array_last() join the array function family. I show what the final syntax looks like and how it changes real code.
