The current function `CHECK_HEADER_ADD_INCLUDE()` automatically defines `HAVE_<HEADER_NAME_H>` preprocessor macros, which makes it difficult to sync with other build systems. Specially, if some `HAVE_` macro is used in the code and this function defines this macro but Autotools doesn't. The new `CHECK_HEADER()` function behaves similar except it doesn't define the `HAVE_<HEADER_NAME_H>` preprocessor macro. This removes the following unused compile definitions: HAVE_ARGON2_H HAVE_AVIF_H HAVE_BZLIB_H HAVE_CAPSTONE_CAPSTONE_H HAVE_CURL_EASY_H HAVE_DB_H HAVE_DECODE_H HAVE_DEPOT_H HAVE_EDITLINE_READLINE_H HAVE_ENCHANT_H HAVE_ENCODE_H HAVE_FFI_H HAVE_FIREBIRD_INTERFACE_H HAVE_FT2BUILD_H HAVE_GD_H HAVE_GLIB_H HAVE_GMP_H HAVE_HTTPD_H HAVE_IBASE_H HAVE_IR_IR_H HAVE_KECCAKHASH_H HAVE_LBER_H HAVE_LDAP_H HAVE_LIBEXSLT_EXSLT_H HAVE_LIBINTL_H HAVE_LIBPQ_FE_H HAVE_LIBTIDY_TIDY_H HAVE_LIBXML_PARSER_H HAVE_LIBXML_TREE_H HAVE_LIBXML_XMLWRITER_H HAVE_LIBXSLT_XSLT_H HAVE_LMDB_H HAVE_MBSTRING_H HAVE_MYSQL_H HAVE_ONIGURUMA_H HAVE_OPENSSL_SSL_H HAVE_PNG_H HAVE_SNMP_H HAVE_SODIUM_H HAVE_SQLITE3_H HAVE_SQLITE3EXT_H HAVE_SYBFRONT_H HAVE_TIDY_H HAVE_TIDY_TIDY_H HAVE_TIDYBUFFIO_H HAVE_TIMELIB_CONFIG_H HAVE_UNICODE_USPOOF_H HAVE_UNICODE_UTF_H HAVE_XPM_H HAVE_ZIP_H HAVE_ZIPCONF_H HAVE_ZLIB_H The following compile definitions are defined explicitly: - HAVE_ICONV_H - HAVE_MSCOREE_H - HAVE_SQL_H - HAVE_SQLEXT_H Additionally, the `SETUP_OPENSSL()` function doesn't accept the 6th argument anymore.
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.
For a minimal PHP build from Git, you will need autoconf, bison, and re2c. For a default build, you will additionally need libxml2 and libsqlite3.
On Ubuntu, you can install these using:
sudo apt install -y pkg-config build-essential autoconf bison re2c libxml2-dev libsqlite3-dev
On Fedora, you can install these using:
sudo dnf install re2c bison autoconf make libtool ccache libxml2-devel sqlite-devel
On MacOS, you can install these using brew:
brew install autoconf bison re2c libiconv libxml2 sqlite
or with MacPorts:
sudo port install autoconf bison re2c libiconv libxml2 sqlite3
Generate configure:
./buildconf
Configure your build. --enable-debug is recommended for development, see
./configure --help for a full list of options.
# For development
./configure --enable-debug
# For production
./configure
Build PHP. To speed up the build, specify the maximum number of jobs using the
-j argument:
make -j4
The number of jobs should usually match the number of available cores, which
can be determined using nproc.
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 or TESTS:
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.
Use the TEST_PHP_ARGS or TESTS variable to test only specific directories:
make TESTS=tests/lang/ test
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 superuser
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 github.com/php/php-src. Contributions are most welcome by forking the 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 don't require an RFC. If the bug has a GitHub issue, reference it in
the commit message using GH-NNNNNN. Use #NNNNNN for tickets in the old
bugs.php.net bug tracker.
