Introspection Beyond the Reflection API: get_class, instanceof and is_callable in Detail

Maxim Mironjuk - February 24, 2026

Not every question about an object's structure needs ReflectionClass. PHP ships a set of lightweight introspection functions, from get_class through instanceof to is_callable, that avoid the overhead of the Reflection API and are entirely sufficient for most everyday type checks.

Rector: Automated Refactoring for PHP Version Upgrades

Maxim Mironjuk - February 14, 2026

Rector automated refactoring replaces manual search and replace during PHP version upgrades with AST-based code rewriting: constructor property promotion, readonly properties, match expressions and the nullsafe operator are applied mechanically and repeatably across an entire codebase, including dry-run preview, custom rules and CI integration against regressions.

Array Functions Performance Comparison: array_map, foreach, Generators

Maxim Mironjuk - February 14, 2026

Switching randomly between array_map, foreach and generators on large datasets risks unnecessary memory usage and hard to predict runtimes. This article compares the most important array functions in PHP 8.4 with real benchmarks, shows when generators with yield make the decisive difference, and provides clear decision rules for everyday project work.

declare(strict_types=1): Why It Belongs in Every New File

Maxim Mironjuk - February 11, 2026

strict_types turns off PHP's automatic, silent type conversion for the current file: a string passed to an int parameter, a float passed to an int parameter, or a wrong return type all trigger an immediate TypeError instead of being quietly converted to another type, which surfaces bugs years earlier, right at the call site instead of somewhere deeper in the code.

Database Migrations Without a Framework in PHP

Maxim Mironjuk - February 05, 2026

Database migrations are versioned, traceable schema changes that every team runs without manual ALTER TABLE commands over SSH connections. A custom built migration system made of a migrations table, up and down methods and a lean CLI runner covers the core requirements without introducing Doctrine Migrations or Laravel as a dependency.

Database Connection Pooling in PHP Applications

Maxim Mironjuk - February 01, 2026

Classic PHP in the shared-nothing model has no true in-memory connection pool within a single process. Anyone who still wants to avoid the overhead of constant reconnects needs either persistent connections with clear boundaries, an external connection pooler like ProxySQL, or a long-running process model like Swoole.

PSR Standards Overview: PHP FIG Interoperability from PSR 3 to PSR 20

Maxim Mironjuk - February 01, 2026

PSR standards are the reason why any logger, any cache adapter and any HTTP client are interchangeable in practically every modern PHP project, without application code needing to change. Anyone who knows the most important PSR standards, from logging through caching to event dispatching, chooses libraries more deliberately and avoids unnecessary coupling to a single vendor.

Generating Secure Random Numbers in PHP

Maxim Mironjuk - January 31, 2026

Not every random number in PHP is equally secure. While rand() and mt_rand() are fine for games and simulations, they are dangerously predictable for tokens, password reset links or cryptographic keys. random_bytes, random_int and the Randomizer class from PHP 8.2 deliver genuinely cryptographically secure random values for exactly these cases.

PHP Enums: Backed vs. Pure Enums Compared

Maxim Mironjuk - January 30, 2026

Class constants and magic strings have not been a necessary evil since PHP 8.1. PHP Enums bring genuine type safety to finite sets of values: Pure Enums for purely internal states, Backed Enums for persistence and API compatibility, plus methods, interfaces and safe conversion with from() and tryFrom().

Functional Error Handling in PHP with Maybe and Either

Maxim Mironjuk - January 16, 2026

Maybe and Either make an error state part of the return type, instead of hiding it implicitly behind null or a thrown exception. In PHP 8.4 both types can be fully rebuilt with readonly classes and enums, without any external library.
