Question

How to install/remove additional PHP versions provided by Plesk?

Answer

Additional PHP versions can be installed/removed by a Plesk administrator only. This can be done either via a Plesk interface (web-browser) or a command-line interface directly on a Plesk server.

Note: Ubuntu 18.04 and Debian 9 do not support PHP 5.6 and lower versions. Visit this KB article for details.

PHP 7.x versions are available starting from Plesk Onyx.

Installing/removing additional PHP versions via the Plesk interface

Note: Make sure that port 8447 is opened in firewall. If it is closed and cannot be opened, use the command-line instructions.

In Plesk, go to Tools & Settings and click Updates (Updates and Upgrades).
On the Updates and Upgrades page, click Add/Remove Components.
On the Add/Remove Components page, expand:
- Web hosting > PHP interpreter versions section, if this is a Linux server.
- Plesk hosting feature section, if this is a Windows server.
Select required PHP versions for installation/uninstallation and click Continue.

Installing/removing additional PHP versions via a command-line interface

Connect to a Plesk server via SSH (Linux) / RDP (Windows Server).
Get the list of all available Plesk components (on Windows Server, use a command prompt as an Administrator):

MYSQL_LIN: plesk installer --select-release-current --show-components
Install/remove additional PHP versions using the component name from step 2.

Example of the command to install PHP 7.4:

Note: PHP 7.4 is available starting from Plesk Obsidian 18.0.21 Update 4.
- for Linux:
  
  # plesk installer add --components php7.4
- for Windows Server:
  
  C:\> plesk installer add --components php74
Example of the command to remove PHP 5.6:
- for Linux:
  
  # plesk installer remove --components php5.6
- for Windows Server:
  
  C:\> plesk installer remove --components php56

Hi - this is all fine for the FPM and CGI versions but how do you install the latest PHP-CLI builds? I need these for running symphony etc apps.

Hi @Hywel Jones,

PHP-CLI should be there when you install it as additional component via Plesk. For example, on Debian 9:

# apt search php-cli
Sorting... Done
Full Text Search... Done
php-cli/stable,stable 1:7.0+49 all
command-line interpreter for the PHP scripting language (default)
php-cli-prompt/stable,stable 1.0.2+dfsg-1 all
tiny helper prompting for user input
plesk-php70-cli/stretch,now 7.0.32-debian9.0.18091413 amd64 [installed]
Command-line interface for PHP
plesk-php71-cli/stretch,now 7.1.22-debian9.0.18091413 amd64 [installed]
Command-line interface for PHP
plesk-php72-cli/stretch,now 1:7.2.10-debian9.0.18091411 amd64 [installed]
Command-line interface for PHP

# dpkg-query -L plesk-php72-cli
/.
/etc
/etc/psa
/etc/psa/php_versions.d
/etc/psa/php_versions.d/plesk-php72-cgi.conf
/etc/psa/php_versions.d/plesk-php72-fastcgi.conf
/opt
/opt/plesk
/opt/plesk/php
/opt/plesk/php/7.2
/opt/plesk/php/7.2/bin
/opt/plesk/php/7.2/bin/lsphp
/opt/plesk/php/7.2/bin/phar.phar
/opt/plesk/php/7.2/bin/php
/opt/plesk/php/7.2/bin/php-cgi
/opt/plesk/php/7.2/bin/phpdbg
/opt/plesk/php/7.2/bin/phar

So all binaries are located at /opt/plesk/php/7.2/bin/ (for PHP 7.2). This is actual for other operation systems as well.

@ Alexandr Shadrin

Thanks - that all works fine now - for some reason the day I made the query I was getting the PHP FPM version afting setting PATH=/opt/plesk/php/7.2/bin:$PATH and typing php -v - my Laravel artisan commands were failing with weird errors. Today it is all good !

Hi @Richie Tjin,

I've just checked it on Ubuntu 18 with Plesk Obsidian 18.0.21.4 and it shows for me.
Please try one more time.

Note: php 7.4 isn't supported on CentOS 6, Red Hat Enterprise Linux 6, and CloudLinux 6.

@Lenor

I has it in Plesk Obsidian 18.0.23 on Debian 8:
```
Select the components you want to install:
1. [=] PHP 7.4
2. [=] PHP 7.3
3. [ ] PHP 7.2
4. [ ] PHP 7.1
5. [ ] PHP 7.0
...
```
Try to update Plesk to 18.0.23, if still isn't:
```
# plesk installer upgrade 18.0.23
```
