Best-Practice Resources Index

Use primary documentation and maintained standards when deciding how PHP code should behave. Blog posts can help explain a topic, but they should not silently become the authority for language or library contracts.

Use This Reference When

  • Checking a PHP-language fact.
  • Reviewing an ecosystem interface.
  • Confirming security guidance.

Preferred Starting Points

PHP language and extensions: https://www.php.net/manual/en/
Composer:                    https://getcomposer.org/doc/
PHP-FIG standards:           https://www.php-fig.org/psr/
OWASP application security:  https://cheatsheetseries.owasp.org/

Record review sources in lessons, pull requests, and operational notes when a claim affects compatibility or security.

Practice

Verify a Claim

Choose one PHP behaviour used in your codebase and locate its primary documentation page. Record the URL and the exact contract you checked.

Show solution

Use the PHP manual or relevant primary project documentation. Summarise the contract in your own words and include a runnable verification when practical.
