# hphpa **hphpa** is a convenience wrapper for [HipHop](http://github.com/facebook/hiphop-php/)'s static analyzer. ## Installation `hphpa` should be installed using the PEAR Installer, the backbone of the [PHP Extension and Application Repository](http://pear.php.net/) that provides a distribution system for PHP packages. Depending on your OS distribution and/or your PHP environment, you may need to install PEAR or update your existing PEAR installation before you can proceed with the following instructions. `sudo pear upgrade PEAR` usually suffices to upgrade an existing PEAR installation. The [PEAR Manual ](http://pear.php.net/manual/en/installation.getting.php) explains how to perform a fresh installation of PEAR. The following two commands (which you may have to run as `root`) are all that is required to install `hphpa` using the PEAR Installer: pear config-set auto_discover 1 pear install pear.phpunit.de/hphpa After the installation you can find the `hphpa` source files inside your local PEAR directory; the path is usually `/usr/lib/php/SebastianBergmann/HPHPA`. ## Usage Example ➜ ~ hphpa --checkstyle hphpa.xml /usr/local/src/code-coverage/PHP hphpa 1.3.0 by Sebastian Bergmann. Using ruleset /usr/share/pear/data/hphpa/ruleset.xml /usr/local/src/code-coverage/PHP/CodeCoverage/Filter.php 206 Too many arguments in function or method call: $this->addFileToWhitelist($file, FALSE) Found 1 violation in 1 file (out of 21 total files). ➜ ~ cat hphpa.xml <?xml version="1.0" encoding="UTF-8"?> <checkstyle> <file name="/usr/local/src/code-coverage/PHP/CodeCoverage/Filter.php"> <error line="206" message="Too many arguments in function or method call: $this-&gt;addFileToWhitelist($file, FALSE)" source="HipHop.PHP.Analysis.TooManyArgument" severity="error"/> </file> </checkstyle>
