Yar can be installed in one of three ways: via PECL, via PIE, or by building it from source.
This » PECL extension is not bundled with PHP.
Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: » https://pecl.php.net/package/yar.
Windows binaries (DLL files) for this PECL extension are available from the PECL website.
Example #1 Installing Yar with PECL
pecl install yar
As of Yar 2.4.0, the extension can be installed with » PIE, the PHP Installer for Extensions, by running the following on the command line.
Example #2 Installing Yar with PIE
pie install laruence/yar
The msgpack packager can be enabled at install time:
Example #3 Installing Yar with PIE and msgpack
pie install laruence/yar --enable-msgpack
The source code is hosted on » GitHub. To build the extension from source, run the following on the command line, replacing the paths with those of the local PHP installation.
Example #4 Building Yar from source
/path/to/phpize ./configure --with-php-config=/path/to/php-config make && make install
The following configure options are available:
Location of the cURL installation, if it is not found in the default include paths.
Enables the msgpack packager and makes the
msgpack extension an optional dependency. When
Yar is built with this option, the default value of
yar.packager becomes
msgpack.
Uses Linux epoll instead of
select() for I/O multiplexing, available as of
Yar 2.1.2. This can improve
Yar_Concurrent_Client performance under
high concurrency. It only takes effect on Linux; on other
platforms it is silently ignored.
