How Can I Install Php7.4 On Ubuntu 19.04

Before we dive into the steps, let’s summarize it:

Now, let’s proceed with a detailed explanation over these steps,

The first step is adding the Ondřej Surý PPA repository. The reason behind this is that it has a more updated PHP version compared to what’s available in Ubuntu default repositories. You can add the repository by running the following command:

sudo add-apt-repository ppa:ondrej/php

Next, you need to update your system packages so that it can recognize this newly added repository. Run this command:

sudo apt-get update

After the update, install PHP7.4 using the apt install command. Apt is a package handling utility for Debian based systems like Ubuntu. Run the command:

sudo apt-get install php7.4

Finally, once the installation is complete, verify if PHP7.4 has been successfully installed. You can do this by checking the installed PHP version with the command:

php -v

Once done, your terminal would display the current PHP version which should be PHP7.4. These steps, when followed correctly, will allow you to install PHP7.4 on Ubuntu 19.04 effectively.

Elaborating further, PHP is a widely-used open source language especially suited for web development and can be embedded into HTML, MySQL, JavaScript or CSS, thus understanding its installation process and usability can potentially boost the performance and speed of your web pages.

sudo apt install php7.4

This command will install PHP7.4 on your Ubuntu 19.04 system.

Additional Tools:

We may also want some additional tools and packages that help PHP be more versatile, such as MySQL support and others,

Such systems can be installed with this command:

sudo apt install php7.4-mysql php7.4-gd php7.4-xml php7.4-json php7.4-curl php7.4-mbstring

This will set you up with full PHP functionality on your server.

Step 4: Verify PHP Installation

In the last step, after a successful installation of PHP7.4 on your system, you can verify the installed version of PHP using the php -v command.

This approach is both systematic and easy-to-follow if you’re familiar with Ubuntu’s Terminal interface, which allows coders and developers to control every aspect of their system. For beginners or those interested in mastering PHP over on Ubuntu 19.04, I recommend diving deeper into learning PHP fundamentals. Learning how these installation and configuration processes work can give a clearer insight into coding prowess.

While installing different versions, substitute ‘7.4’ in the above commands with your required version. Or check multiple PHP versions availability from Ondřej Surý repository.

Whilst installing PHP 7.4 on Ubuntu 19.04, you may encounter a few common issues that can stall or halt the installation process entirely. This guide delineates upon the prominent problems and provides solutions to help you navigate through these difficulties effectively.

1. Missing Packages

In some cases, essential packages might not be available in the default repository of Ubuntu 19.04 for PHP 7.4 installation. If it’s happening with you, consider adding an external Personal Package Archive (PPA) by Ondřej Surý, who maintains PHP packages for Ubuntu.

Here is how to add the PPA and install PHP 7.4:

sudo apt-get install software-properties-common  
sudo add-apt-repository ppa:ondrej/php  
sudo apt-get update

2. Conflicts with Older PHP Versions

If older versions of PHP are already installed on your system, it might cause conflicts during PHP 7.4 installation.
You need to remove the older version first:

sudo apt-get purge 'php*'

After this, proceed with the PHP 7.4 installation using commands listed above.

3. Extensions Compatibility

The third major common hindrance comes from extension compatibility. Some extensions might not yet support PHP 7.4. Before upgrading, ensure all key PHP extensions run properly on PHP 7.4. You can check each extension’s compatibility visiting their official documentation or community discussions on platforms like StackOverflow.

4. Missing SSL Certificates

At times, error messages regarding SSL certificates might surface. If such is the case, try installing the ‘ca-certificates’ package:

sudo apt-get install ca-certificates

Then attempt re-installation of PHP 7.4.

5. Permissions Issue

Permission-related issues might also hinder the installation. Verify whether you have sufficient rights to download and install new packages on your system. Usually, administrator or ‘sudo’ privileges are necessary. If you’re unsure about the same, contact the system administrator or run your command with ‘sudo’.
