Description
Legacy PHP 8.0 applications can stream-read XML documents without loading each file into memory. This runtime extension adds the XMLReader API used by scripts, CMS plugins, importers, and backend jobs that parse feeds, configuration files, or document formats. It is dependency-only and has no separate app launcher; installed PHP code loads it when the extension is enabled. Treat untrusted XML as risky because entity expansion, oversized files, and malformed input can waste resources or expose parser bugs.
