PHP is an HTML-embedded scripting language. Much of its syntax is borrowed from C, Java and Perl with a couple of unique PHP-specific features thrown in. The goal of the language is to allow web developers to write dynamically generated pages quickly.
/DontAddToPath - Do not add install directory to path/InstallDir - Override the installation directory (needs to be specified both during install and update, until it is remembered by choco)/ThreadSafe - Install the thread safe version of php that is compatible with Apache.These parameters can be passed to the installer with the use of --params.
For example: --params '"/ThreadSafe ""/InstallDir:C:\PHP"""'.
