PHP 5.3 has a new feature called PHAR similar to JAR in JAVA. It\'s basically a archive of PHP files. What are its advantages
In my experience, loosely packaged PHP source files sitting in a production environment invite tinkering with live code when a fix is needed. Deploying in a .phar file discourages this behaviour and helps reinforce better practices, i.e. build and test in a local environment, then deploy to production.
