According to RFC: https://wiki.php.net/rfc/union_types_v2 The type representation now makes use of both the pointer payload and the type mask at the same time. Additionall, zend_type_list is introduced as a new kind of pointer payload, which is used to store multiple class types. Each of the class types is a tagged pointer, which may be either a class name or class entry. The latter is only used for typed properties, while arguments/returns will instead use cache slots. A type list can contain a mix of both names and CEs at the same time, as not all classes may be resolvable. One thing this is missing is support for union types in arginfo and stubs, which I want to handle separately. I've also dropped the special object code from the JIT implementation for now -- I plan to add this back in a different form at a later time. For now I did not want to include non-trivial JIT changes together with large functional changes. Another possible piece of follow-up work is to implement "iterable" as an internal alias for "array|Traversable". I believe this will eliminate quite a few special-cases that had to be implemented. Closes GH-4838.
The PHP Interpreter
PHP is a popular general-purpose scripting language that is especially suited to web development. Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world. PHP is distributed under the PHP License v3.01.
Documentation
The PHP manual is available at php.net/docs.
Installation
Prebuilt packages and binaries
Prebuilt packages and binaries can be used to get up and running fast with PHP.
For Windows, the PHP binaries can be obtained from
windows.php.net. After extracting the archive the
*.exe files are ready to use.
For other systems, see the installation chapter.
Building PHP source code
For Windows, see Build your own PHP on Windows.
PHP uses autotools on Unix systems to configure the build:
./buildconf
./configure [options]
See ./configure -h for configuration options.
make [options]
See make -h for make options.
The -j option shall set the maximum number of jobs make can use for the
build:
make -j4
Shall run make with a maximum of 4 concurrent jobs: Generally the maximum
number of jobs should not exceed the number of cores available.
Testing PHP source code
PHP ships with an extensive test suite, the command make test is used after
successful compilation of the sources to run this test suite.
It is possible to run tests using multiple cores by setting -jN in
TEST_PHP_ARGS:
make TEST_PHP_ARGS=-j4 test
Shall run make test with a maximum of 4 concurrent jobs: Generally the maximum
number of jobs should not exceed the number of cores available.
The qa.php.net site provides more detailed info about testing and quality assurance.
Installing PHP built from source
After a successful build (and test), PHP may be installed with:
make install
Depending on your permissions and prefix, make install may need super user
permissions.
PHP extensions
Extensions provide additional functionality on top of PHP. PHP consists of many essential bundled extensions. Additional extensions can be found in the PHP Extension Community Library - PECL.
Contributing
The PHP source code is located in the Git repository at git.php.net. Contributions are most welcome by forking the GitHub mirror repository and sending a pull request.
Discussions are done on GitHub, but depending on the topic can also be relayed to the official PHP developer mailing list internals@lists.php.net.
New features require an RFC and must be accepted by the developers. See Request for comments - RFC and Voting on PHP features for more information on the process.
Bug fixes do not require an RFC but require a bug tracker ticket. Open a
ticket at bugs.php.net and reference the bug id using
#NNNNNN.
Fix #55371: get_magic_quotes_gpc() throws deprecation warning
After removing magic quotes, the get_magic_quotes_gpc function caused a
deprecated warning. get_magic_quotes_gpc can be used to detect the
magic_quotes behavior and therefore should not raise a warning at any time.
The patch removes this warning.
Pull requests are not merged directly on GitHub. All PRs will be pulled and pushed through git.php.net. See Git workflow for more details.
