I use the following command to view installed PHP versions in Ubuntu:
sudo update-alternatives --list php
Second way go to php directory where all PHP version configuration file stored:
cd /etc/php
dir

Since you have a Linux environment, you can run this on your console:
locate bin/php
And then for anything that looks like a PHP binary, get the version. The output for me for the above is:
/home/xx/Development/Personal/Project1/webapp/bin/phpunit
/home/xx/Development/Personal/Project1/webapp-backup/vendor/bin/phpunit
/home/xx/Development/Personal/Project2/app/vendor/bin/phpunit
/home/xx/php-threaded/bin/php
/home/xx/php-threaded/bin/php-cgi
/home/xx/php-threaded/bin/php-config
/home/xx/php-threaded/bin/phpize
/usr/bin/php
/usr/bin/php5
/usr/local/bin/php-cgi
/usr/local/bin/php-config
/usr/local/bin/php53
/usr/local/bin/phpize
/usr/sbin/php5dismod
/usr/sbin/php5enmod
/usr/sbin/php5query
Out of those, there are a few that look like PHP binaries. So let's get the version for each:
/home/xx/php-threaded/bin/php -v
/usr/bin/php -v
/usr/bin/php5 -v
/usr/local/bin/php53 -v
That will give you the versions of PHP you have installed.
I wouldn't bother deleting an old version, it might remove files that will stop things working. You can just configure the console version, or the Apache version, to use the version you want.
In answer to your supplementary question: it seems that you've followed the instructions here to add an unofficial repo to your version of Ubuntu, since the standard repo does not support 5.5.
We discovered together that the way to get it working was first to upgrade Apache from 2.2 to 2.4:
sudo apt-get upgrade apache2
It should be noted that this can cause some vhost repair to be required, as some Apache directives changed in this version. Once you have done that, you can get the new version of mod_php:
sudo apt-get install libapache2-mod-php5
How to check PHP version?
The URL given is one that works with the script they provide or expect you to write. There's no built-in "magic URL" to show that information with PHP. A HTML page of configuration information can be generated in PHP code using phpinfo() You may also want to pay attention to the top section of phpinfo() output that lists the ini files read, to make sure you're editing the right files. This same information is available on the command line through the following commands: php -i (full information similar to phpinfo()) php -m (enabled modules / extensions) php -v (version) php --ini (ini files read) See also php --help for more command-line options. Note that you can also set most ini settings at runtime in a script using ini_set() . In this specific case see also the error_reporting() function. More on reddit.com

It should be noted that PHP on the command line does not have to be the same version as the one called by the web server. It's also possible for the server to be calling different versions for different sites. If you've many versions installed, it's more likely to be the case. If you can't figure it out from, or don't have access to, the server config, you can check by calling phpversion() within each site. https://www.php.net/manual/en/function.phpversion.php Also, if your server isn't configured not to (ideally it should be, if public), every page will be served with the X-Powered-By header starting which version of PHP is being used.
