slice2php Command-Line Options

The Slice-to-PHP compiler, slice2php, offers the following command-line options in addition to the standard options:

  • --all
    Generate code for all Slice definitions, including those included by the main Slice file.
  • --no-namespace
    Generate code without support for PHP namespaces (deprecated).
  • --checksum
    Generate checksums for Slice definitions.

Compiler Output in PHP

For each Slice file X.ice, slice2php generates PHP code into a file named X.php in the output directory. The default output directory is the current working directory, but a different directory can be specified using the --output-dir option.

Include Files in PHP

It is important to understand how slice2php handles include files. In the absence of the --all option, the compiler does not generate PHP code for Slice definitions in included files. Rather, the compiler translates Slice #include statements into PHP require statements in the following manner:

  1. Determine the full pathname of the included file.
  2. Create the shortest possible relative pathname for the included file by iterating over each of the include directories (specified using the -I option) and removing the leading directory from the included file if possible.
    For example, if the full pathname of an included file is /opt/App/slice/OS/Process.ice, and we specified the options -I/opt/App and -I/opt/App/slice, then the shortest relative pathname is OS/Process.ice after removing /opt/App/slice.

  3. Replace the .ice extension with .php. Continuing our example from the previous step, the translated require statement becomes

    require_once "OS/Process.php";

    As a result, you can use -I options to tailor the require statements generated by the compiler in order to avoid absolute path names and match the organizational structure of your application's source files.
