How to update my PHP to latest version by entering through SSH on my server

I need to update my PHP to latest version, but I'm not getting, currently it is in version 5.5.9, I would like to leave it in the latest version, so I can install Laravel.

I tried using Php7 apt-get command but gave error.

  • How do I quit PHP 5.5.9
  • How do I install PHP 7.3 + ?

Note: I'm wanting to update, why according to this video ( https://www.youtube.com/watch?v=iPTxznidNHo&list=PLVSNL1PHDWvR3PeLXz6nvBkDhv1IQk4wP ) it leaves the latest version, but when I get on github of it the installation comes with the old version of PHP.

Edit: I used the command sudo apt install php7.3 and gave this following message: 

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package php7.3
E: Couldn't find any package by regex 'php7.3'

Then I use the command sudo update-alternatives --set php /usr/bin/php7.2 and the result is: 

update-alternatives: error: alternative /usr/bin/php7.2 for php not registered; not setting

I tried restarting Apache2 to check if it was, but to no avail.

Edit2: I ran the command: sudo apt update && apt upgrade and returned:

I had this same problem when trying to upgrade to version 7.2.

When you run the command sudo update-alternatives --help you have a list of available commands and among them the command --install which has the following syntax: 

sudo update-alternatives --install <link> <nome> <caminho> <prioridade>

Where:

  • <link> is a symbolic link that points to/etc/alternatives / <nome>.
  • <nome> is a master name for this link group, in this case php.
  • <caminho> is the location of one of the target files of the alternative, in my case the path is/usr / bin / php7.2.
  • <prioridade> is an integer; options with larger numbers have higher priority in automatic mode.

In my case the command looked like this: 

sudo update-alternatives --install /usr/bin/php php /usr/bin/php7.2 72

This last number could be any number, I only chose 72 to match the php version.

After performing these steps, if you run sudo update-alternatives --config php you will see more than one php option installed, and you can choose which option simply by choosing the number referring to the option displayed in the listing.

Example: 

  Selecção   Caminho          Prioridade Estado
------------------------------------------------------------
  0            /usr/bin/php7.4   74        modo automático
  1            /usr/bin/php7.1   71        modo manual
* 2            /usr/bin/php7.2   72        modo manual
  3            /usr/bin/php7.4   74        modo manual

Press <enter> to keep the current choice[*], or type selection number:

Hope I helped!
