This document summarizes best practices for PHP coding standards, documentation, version control, and security. It recommends using an established coding standard like Zend or PEAR for consistency. It also recommends the PHP_CodeSniffer tool to check standards, and phpDocumentor for documenting code. Subversion is presented as an option for version control. For security, it emphasizes filtering all input and escaping all output.
