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
Output:
> 5.6 7.0 7.1

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

Do it from your command line:
php -v
mysql -V
and:
php -i | grep -i '^libxml'
OR
Put this in your root directory:
<?php
phpinfo();
php?>
Save it as phpinfo.php and point your browser to it (this could be http://localhost/phpinfo.php)
Use dpkg to find the installed package versions.
dpkg -l | grep '\(php\|mysql\)'
This command works while running in PHP
<?php
echo PHP_VERSION;
You can get it in bash, like
PHP_VERSION=$(php -r "echo PHP_VERSION;")
Here is all of PHP Predefined Constants
I got it to work with the following commands:
# Full version
php -v | head -n 1 | cut -d " " -f 2
# Major.Minor version
php -v | head -n 1 | cut -d " " -f 2 | cut -f1-2 -d"."
You can login on server by putty with same detail (FTP login detail) and run following command:
uname -a
Or, you can execute PHP shell command to get OS info.
You can use shell_exec which is a PHP function, which runs your shell command and returns the output of it.
See this page as reference: PHP: shell_exec - Manual
So by combining this function and uname, lscpu, free and do little text processing you can get what you want.
hi, I'm new to PHP.
I want to change display_errors to On for debugging, but see many PHP versions installed.
I thought going to http://localhost/first/index.php?language=English&page=phpinfo would give me the version , but it just renders the regular index page.
