PHPBrew vs rustup

PHPBrew builds and installs multiple PHP versions in a user’s home directory, including without root permission. It is intended for Linux and macOS and compiles PHP from source. Build variants simplify configuration choices such as PDO, MySQL, SQLite, and debug support. Users can temporarily select a version or change the default, with bash and zsh integration for switching and project version pinning. PHPBrew installs extensions from PHP source or PECL and can create configuration to enable them. It can compile Apache PHP modules and provides PHP-FPM management commands when PHP is built with the +fpm variant. Library lookup can use Homebrew, MacPorts, Debian, Ubuntu, or a custom path. Development packages must be installed before building. The project uses the MIT license and directs users to troubleshooting and wiki documentation. Builds of PHP versions no longer officially supported are not guaranteed, and issues involving versions older than 5.4 will not be fixed. The listed plan costs nothing.

rustup installs Rust from its official release channels and manages the toolchains and supporting components developers use. It can switch among stable, beta, and nightly compilers, keep toolchains updated, and install specific versions or dated releases. For cross-compilation, add a target’s standard library with `rustup target add`; Android builds also require the Android NDK and usually a linker. rustup manages official channels, archived releases, alternate hosts, and local builds. It installs command proxies for tools including rustc, rustdoc, Cargo, rust-analyzer, Clippy, and Miri. Component availability varies by release and toolchain, especially for nightly. Installation uses a shell script on Unix and rustup-init.exe on Windows. Downloads use HTTPS, but download signatures are not yet validated. rustup is free and open source, with a free plan. Its listed supported platforms are Linux, macOS, and Windows; the installer also runs on FreeBSD, NetBSD, Solaris, and illumos.
