Description
Legacy PHP 8.1 applications can make HTTP, HTTPS, and other network requests through libcurl. This runtime extension is needed by API clients, webhook handlers, payment integrations, downloaders, and many frameworks that communicate with remote services. It is dependency-only and has no separate launcher; PHP code calls cURL functions when enabled. TLS verification, redirects, proxy settings, credentials, timeouts, and user-controlled URLs need review to avoid data leaks or server-side request abuse.
