Nikita Popov 333d607d47 Fix bug #77930: Remove mmap limit
First, the limitation already doesn't trigger if you copy the whole
file (i.e. use copy() or stream_copy_to_stream() and don't specify
a length). This happens because length will be 0 at the time of the
check and only later calculated based on the file size. This means
that we're already completely blowing the length limit for what is
likely the most common case, and it doesn't seem like anyone complained
about that.

Second, the premise of the code comment ("to avoid runaway swapping")
seems incorrect to me. Because this performs a file-backed non-private
mmap, no swap backing is needed for the mapping. Concerns over "memory
usage" are also misplaced, as this is a virtual mapping.

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.

Build status Build status Build Status

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.

Guidelines for contributors

See further documents in the repository for more information on how to contribute:
