Introduction

Vito supports multiple PHP versions, and you can install and uninstall them during the server creation or after the server creation in the PHP menu in the server page or in the Services page.

Supported PHP Versions

PHP 7.0
PHP 7.1
PHP 7.2
PHP 7.3
PHP 7.4
PHP 8.0
PHP 8.1
PHP 8.2
PHP 8.3
PHP 8.4

Install and Uninstall

Vito gives you the option to easily install and uninstall different PHP versions.

You cannot uninstall a PHP version if you have a site running with that PHP version. You need to first change the PHP version of the website first.

Install PHP Extensions

Vito supports some of the PHP extensions and enables you to install them.

To install a new PHP extension you can go to the PHP page and for each PHP version you can click on the Actions dropdown and Install a new extension.

Available extensions to install:

imagick
exif
gmagick
gmp
intl
opcache

You can also develop a plugin to add a new PHP extension to Vito.

Default PHP Cli

Although you can have only one default PHP Cli which can be called by php command on the server, But you can switch the default cli version in the PHP page.

Edit php.ini

Vito enables you to edit the php.ini file of each PHP version. You can edit both the php.ini file of the CLI and the FPM.

FPM service

Under the PHP or Services page, you can start, stop, restart, enable, or disable the FPM service for each PHP version.

Troubleshooting

`apt-get update` fails with "Repository ... changed its 'Label' value"

When installing a PHP version, or updating a server that already has PHP installed, you may see an error like this:

Text

E: Repository 'https://ppa.launchpadcontent.net/ondrej/php/ubuntu noble InRelease' changed its 'Label' value from 'PPA for PHP' to 'Use packages.sury.org/php instead'

Vito 3.x installs PHP from the ondrej/php Launchpad PPA. That PPA is being merged into packages.sury.org, and as part of the move it changed the Label field in its release metadata to announce this. APT treats a changed Label (along with Origin, Suite, or Version) as a potential security concern and refuses to refresh that repository's package list unless you explicitly allow it — which aborts the whole apt-get update, and with it the PHP install or server update that triggered it.

This fix is only available as a manual workaround for 3.x. It is not being backported into Vito's 3.x install/update scripts, so you'll need to apply it yourself on each affected server (once per server is enough).

Vito keeps installing PHP from the ondrej/php PPA rather than migrating to packages.sury.org, because that mirror doesn't yet carry every extension package Vito needs (such as php-redis) for all PHP versions. Instead, just tell APT to accept the (expected) label change:

Shell

sudo apt-get update -o Acquire::AllowReleaseInfoChange::Label=true

After that, retry the PHP install or server update in Vito — it should complete normally.
