phc is an open source compiler for PHP with support for plugins. In addition, it can be used to pretty-print or obfuscate PHP code, as a framework for developing applications that process PHP scripts, or to convert PHP into XML and back, enabling processing of PHP scripts using XML tools.
Note: phc is unmaintained. It does compile some programs, and has an advanced optimization framework. However, these are not for production use (notably they lack support for objects!). It has an excellent program transformation framework though, which unfortunately was last updated for PHP 5.2, and does not support newer features. PRs will likely still be read, and if they pass the CircleCI build, I may merge them.
Building from source
After checking out via git, run
$ touch src/generated/* Makefile.in configure Makefile libltdl/aclocal.m4 libltdl/Makefile.in libltdl/configure libltdl/Makefile $ ./configure $ make $ make install
For more detail, see (the manual)(doc/manual).
There's a little bit of work to get it building on OSX:
$ brew install homebrew/versions/boost155 xerces-c boehmgc $ LDFLAGS="-L/usr/local/opt/boost155/lib -L/usr/local/Cellar/bdw-gc/7.6.0/lib" CPPFLAGS="-I/usr/local/opt/boost155/include -I/usr/local/Cellar/bdw-gc/7.6.0/include" ./configure --disable-static --disable-gc
The tests are held in test/framework/, but tests should be run
from this directory.
test/support_files/ are files used by the tests, for
example for regression. test/subjects/ are the files used to
test phc. Most are designed to test some feature or tickle some bug.
test/subjects/labels controls what tests are run on which subjects.
contains logs of failed tests. test/dependencies are used to avoid running a
test if we know it wont work because a previous test failed.
contains the working directory for each test run.
To run tests:
$ make test # aka make check
$ make installcheck
$ make long-test
$ php test/framework/driver.php
The latter allows command line options, and limiting the tests with regular
driver.php with the
-h flag for details.
In order to run tests on your own php files, add the files to
test/subjects/3rdparty/, and list them in
order to generate the support files, for example if you'd like the regression
tests to succeed rather than be skipped, run
$ make generate-test-files
By default, 3rdparty tests are treated as 'long', so need to be run with
$ make long-test
Its also straight-forward to test PHP's phpt test files:
- run the test suite on PHP (in PHP's directory:
$ TEST_PHP_EXECUTABLE=./sapi/cli/php --keep=php). This creates .php files from the .phpt files
- link the PHP phpt directory from
- Run the tests using the .php files.
- This doesnt provide the
EXPECTfunctionality etc, but we dont really need that in the majority of cases.
