PsySH provides an interactive PHP shell which makes it very useful for experimenting with PHP code, debugging, and rapid testing without the need to execute a full script.
Variable Inspection
It allows for easy inspection of variables and information about the current scope, which aids in understanding and debugging code.
Integrated Documentation
PsySH includes documentation lookup features, enabling users to access PHP documentation directly within the shell for convenient reference.
Code Completion
The shell includes auto-completion for classes, functions, and variables, which significantly enhances productivity and reduces syntax errors.
Debugging Tools
PsySH includes built-in debugging tools that help developers troubleshoot and identify issues within their code more effectively.

Possible disadvantages of PsySH

Learning Curve

PHP Version Compatibility
Certain features or functionalities may not be fully compatible with all PHP versions, which could affect usage depending on the user's environment.
Performance Overhead
Running interactive shells can introduce performance overhead, making it less suitable for environments where resources are at a premium.
Limited to CLI
PsySH is designed to run in a command-line environment, which might limit its usability for developers who are more accustomed to GUI-based debuggers.
Dependency Management
As a tool that needs to be installed, it adds an additional dependency that needs to be managed and maintained across different development environments.

Database management in a single PHP file
I do similar things with Elixir scripts, though commonly I still turn to PHP because there is some single file library that does what I want with a lot less ceremony than the Java variety would require. There's also PsySH, https://psysh.org/, for being something other than a Common Lisp or BEAM interface it's a very nice REPL. Besides Picolisp and iex it's the interactive programming environment I use the most. - Source: Hacker News / 7 months ago
Upcoming Hardening in PHP
Https://psysh.org/ It's very popular, as in a lot of businesses use it, it's just not fashionable. I think it's a great tool to have. It had gradual typing before it was cool. You can type in like a page of code including the layout and render whatever in a PDO-supported database on a web page, served by the builtin web server, which is great for data exploration and things like SQL optimisation. At the moment I'm... - Source: Hacker News / 11 months ago
PHP Doesn't Suck Anymore
PHP is great, but you need to be a pretty decent developer to use it effectively. It has a rather nice interactive shell, https://psysh.org/ . I've built non-trivial, non-web systems in it. Concurrency 'within' the language isn't as nice as some alternatives, but the FCGI-style deployment is quite reliable and convenient in practice. - Source: Hacker News / over 1 year ago

OpenAI Codex Review
> incorrect, its an o3 finetune. This is Open AI's fault (and literally every AI company is guilty of the same horrid naming schemes). Codex was an old model based on GPT-3, but then they reused the same name for both their Codex CLI and this Codex tool... I mean, just look at the updates to their own blog post, I can see why people are confused. https://openai.com/index/openai-codex/. - Source: Hacker News / 5 months ago
OpenAI o3 and o4-mini – OpenAI
The big step function here seems to be RL on tool calling. Claude 3.7/3.5 are the only models that seem to be able to handle "pure agent" usecases well (agent in a loop, not in an agentic workflow scaffold[0]). OpenAI has made a bet on reasoning models as the core to a purely agentic loop, but it hasn't worked particularly well yet (in my own tests, though folks have hacked a Claude Code workaround[1]). o3-mini... - Source: Hacker News / 6 months ago
