php-version

A project rule requiring all examples and tutorials to use PHP 8.4. PHP is a programming language commonly used to build websites and server-side applications.

In plain words
What is it for?
Use it when writing PHP examples, tutorials, prerequisites, or Composer package settings. It also points authors toward PHP 8.4 features and documentation.
Why use it?
It keeps the code and documentation consistent with one PHP version. This reduces confusion about which language features and dependency requirements readers should use.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

php-version scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

PHP Version Requirement

This project uses PHP 8.4 exclusively.

Code Requirements

  • All PHP code examples, snippets, and tutorials must be compatible with PHP 8.4
  • Use PHP 8.4 syntax and features where appropriate
  • When showing version-specific features, specify PHP 8.4 compatibility
  • Include php: "^8.4" in any composer.json files or dependency requirements

Documentation

  • Reference PHP 8.4 documentation: https://www.php.net/releases/8.4/
  • When mentioning PHP versions in tutorials, default to 8.4 unless specifically comparing versions
  • Prerequisites sections should specify PHP 8.4 as the required version

Code Examples

  • Use modern PHP 8.4 features including:
    • Property hooks
    • Asymmetric visibility
    • New array functions
    • #[\Override] attribute
    • Type system improvements
    • And other PHP 8.4 capabilities where relevant

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
