+## Multiple builds

+If you need to build multiple times locally, the following method can save you time downloading resources and compiling.
+
+- If you only switch the PHP version without changing the dependent libraries, you can use `bin/spc switch-php-version` to quickly switch the PHP version, and then re-run the same `build` command.
+- If you want to rebuild once, but do not re-download the source code, you can first `rm -rf buildroot source` to delete the compilation directory and source code directory, and then rebuild.
+- If you want to update a version of a dependency, you can use `bin/spc del-download <source-name>` to delete the specified source code, and then use `download <source-name>` to download it again.
+- If you want to update all dependent versions, you can use `bin/spc download --clean` to delete all downloaded sources, and then download them again.
