Old web application(PEAR made) to new LAMP

[Ocellata]

Hi,

I'm new very new to PEAR but I would have to set it to Apache server with PHP and MySQL. The situation is this:

Application is made in wamp environment with Apache 2.4.9, PHP 5.5.12, MySQL 5.6.17.
I have a file with name go-pear.phar which I should set to this folder: wamp/bin/php/php5.5.12/. There I would run the file.

If I have to install old versions of Apache, PHP and MySQL, how should I do it? From where I find them? In Linux the folder structure is different. What is the right folder to run the go-pear.phar in Linux? I tried once, but behind the bin the folders looked very d

...Or if I install the current stuff, which is the right way to install go-pear.phar? I tried once, but behind the bin there were no similar folder in new version.
