# 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 Modified BSD License
(SPDX-License-Identifier: `BSD-3-Clause`).
## 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:
 [code] 
On Fedora, you can install these using:
 [code] 
On MacOS, you can install these using `brew`:
 [code] 
or with `MacPorts`:
 [code] 
Generate configure:
 [code] 
Configure your build. `--enable-debug` is recommended for development, see
`./configure --help` for a full list of options.
 [code] 
Build PHP. To speed up the build, specify the maximum number of jobs using the
`-j` argument:
 [code] 
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.
Tests run in parallel by default, using up to 10 detected logical processors.
Set `-jN` in `TEST_PHP_ARGS` or `TESTS` to override the worker count:
 [code] 
This runs `make test` with a maximum of 4 concurrent jobs. Alternatively,
use `-j1` to run tests sequentially.
Use the `TEST_PHP_ARGS` or `TESTS` variable to test only specific directories:
 [code] 
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:
 [code] 
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 on the
PIE Extensions list, and installed with
🥧 PIE, the PHP Installer for Extensions or the
deprecated 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
