问题
I'm using php 5.3 on my local machine. On our webserver we have php 4.8. Our server is a shared server. So I want to change the php version on our server via .htaccess file. Is it possible to do it? If yes how to do it?

Note that all above answers are correct for Apache+mod-php setups. They're less likely to work with more current PHP-FPM setups. Those can typically only be defined in VirtualHost section, not .htaccess.
Again, this highly depends on how your hoster has configured PHP. Each domain/user will typically have it's own running PHP FPM instance. And subsequently a generic …/x-httpd-php52 type will not be recognized.
See ServerFault: Alias a FastCGI proxy protocol handler via Action/ScriptAlias/etc for some overview.
For Apache 2.4.10+/mod-proxy-fcgi configs you might be able to use something like:
AddHandler "proxy:unix:/var/run/php-fpm-usr123.sock|fcgi://localhost" .php
Or SetHandler with name mapping from your .htaccess. But again, consulting your hoster on the concrete FPM socket is unavoidable. There's no generic answer to this on modern PHP-FPM setups.

Try this to switch to php4:
AddHandler application/x-httpd-php4 .php
Upd. Looks like I didn't understand your question correctly. This will not help if you have only php 4 on your server.

just FYI in GoDaddy it's this:
AddHandler x-httpd-php5-3 .php

You can't change PHP version by .htaccess.
you need to get your server updated, for PHP 5.3 or you can find another host, which serves PHP 5.3 on shared hosting.
