I have a Ubuntu Apache2 server where I have updated PHP to 7.3.
I can see from /etc/php/ PHP-versions from 5.6. to 7.3. installed.
php -r "phpinfo();" | grep php.ini
Confirms me that the latest version is being used.
However, a Wordpress -website running on the server, is still using the old PHP 7.0. How can I configure Wordpress to use the new version instead? I haven't found the php path defined in any of the wordpress files.
After updating the php to version 7.3, you should enable that mode in apache configuration.
Run this command:
sudo a2enmod php7.3

Using the commmand php -v on a Ubuntu 18.04 server is displaying PHP version 8.1.14, but no PHP8.* module is installed.
I have tried running the command: sudo update-alternatives --config php which displays:
Available PHP versions
Disabling the PHP8.1 module will show me that the module is not installed:
module not installed
While php -v is really showing me PHP8.1:
PHP version
I have tried to purge the PHP 8 version with the following command:
sudo apt-get purge php8.*
It showed me 0 modules were marked for removal, just to be sure I also ran autoremove & autoclean commands.
When I display the PHP info, it also shows the 8.1 version:

I need to get the server back to version 7.4 to make some installations function properly, I have tried all options above but did not succeed. How can I downgrade to PHP Version 7.4?
While I was installing the PHP Selector add-on for DirectAdmin, I noticed Zend modules were being installed for 7.4. Perhaps these were missing for the server to switch back to version 7.4. Problem solved!
I have a fresh ubuntu server installed with virtualmin. It autoinstalls Php version 7.2, I need 7.4. So I install 7.4. When I check the version with -v it shows 7.4. However, webmin and wordpress both still see and use only 7.2. I've tried uninstalling 7.2 but the command fails and tells me that module doesn't exist when I can show it in the list of installed versions in ssh. Its just not showing up as an option in virtualmin when I go to change the php version. Only showing 7.2.
Any advice on where I should be looking to resolve this? I'm feeling stumped. Thanks!
You can try with below command :
sudo update-alternatives --set php /usr/bin/php7.4
For more details you can refer below link as well :

The right way of changing PHP version for the given virtual server in Virtualmin is done using Server Configuration ⇾ PHP Options page.
Using update-alternatives command will change default PHP (CLI) version system-wide. It won't be applied to virtual-servers.
You may find our Virtualmin Community forum helpful.
I am unable to find any info on installing PHP 7.4, all the info seems to go untill 7.3 but that has not been helpful.
What I have done so far is execute:
curl -s https://php-osx.liip.ch/install.sh | bash -s 7.4
And this is the message I got:
It doesn't seem to install. How can I solve this problem?
If you check the script https://php-osx.liip.ch/install.sh you can see it only support 7.3
Yes, you can install and upgrade to latest php version on mac without homebrew.
For me I use MacPorts a package manager for MacOS which is similar to HomeBrew but more stable.
Example to upgrade to php74:
sudo port install php74
Install the extensions you need
sudo port install php74-cgi php74-gd php74-curl php74-intl php74-iconv php74-gettext php74-mbstring php74-imap php74-mcrypt php74-xmlrpc php74-mysql php74-openssl php74-sockets php74-zip php74-tidy php74-opcache php74-xsl php74-sqlite
Select php74 as the active PHP version. With this command you can have multiple php version and quickly switch from one to the other.
sudo port select php php74
Check which PHP binary is used (should return /opt/local/bin/php). Perhaps you may need to restart you terminal.
which php
Check the version (should return “PHP 7.4.XX (cli)…”)
php --version
Also, If you use XAMPP ensure to restart Apache Web server.

I am a new Linux Mint user. In my computer I found PHP version 7.1 from phpinfo() like below
I found PHP version 7.4.3 from terminal like below
My /etc/php/ folder is like below
Which PHP version am I using ?
Try in your terminal
which php
your will find your terminal PHP path.
You have multiple versions installed and you're using the version that PHP tells you you are using.
When you use the webserver module version of PHP it is version 7.1.33. When you use the command line version you are using 7.4.3.
You might also have 7.0 and 7.2 installed (or they may be folders for leftover config files in versions that have since been uninstalled).
Disable php 7.1 module on Apache
sudo a2dismod php7.1
and enable php 7.4
sudo a2enmod php7.4
sudo systemctl restart apache2
The php version used by the CLI and the one used by apache CAN be different.
The installed versions are listed in your /etc/php/ folder as you already emntioned.
To switch the used version for apache you can use the following commands:
sudo a2dismod php7.1
sudo a2enmod php7.4
Also you have to restart your apache afterwards.

I have updated PHP 5.5.9 to PHP 5.6.31 using the command lines in Ubuntu.
This is the picture
And then I was trying to install CakePHP, but it is showing that "your PHP version must be equal or higher than 5.6.0 to use CakePHP."
This is the error message of cakePHP
I am doing work in Linux(Ubuntu) Operating system.
What can I do now?
Your PHP CLI version and the version configured with your web server can very well be different. If you check phpinfo(), you can see exactly what paths and what not are in use.
I have found the solution. PHP CLI and PHP Apache are the different module. We have to notice the Apache server PHP version which is showing by-
<?php
phpinfo()
?>
To run the same version, first I disabled the PHP 5.5.9 version-
sudo a2dismod php5
Then I enabled the PHP 5.6 version-
sudo a2enmod php5.6
Restart the server-
sudo service apache2 restart
