To run Piwik you need at least PHP version $piwik_minimumPHPVersion

Unfortunately it seems your webserver is using PHP version $piwik_currentPHPVersion.

Please try to update your PHP version, Piwik is really worth it! Nowadays most web hosts support PHP $piwik_minimumPHPVersion.

Also see the FAQ: My Web host supports PHP4 by default. How can I enable PHP5?

Piwik is not compatible with the directive zend.ze1_compatibility_mode = On

It seems your php.ini file has

zend.ze1_compatibility_mode = On

It makes PHP5 behave like PHP4. If you want to use Piwik you need to set

zend.ze1_compatibility_mode = Off

in your php.ini configuration file, and restart your web server. You may have to ask your system administrator.

It appears the composer tool is not yet installed. You can install Composer in a few easy steps. In the piwik directory, run in the command line the following (eg. via ssh):

 curl -sS https://getcomposer.org/installer | php".
                    "\n php composer.phar install

This will download and install composer, and initialize composer for Piwik (eg. download the twig library in vendor/twig).
Then reload this page to access your analytics reports.

Note: if for some reasons you cannot execute this command, install the latest Piwik release from builds.piwik.org.
