The article is a guide on how to install PHP 8.0 on Ubuntu 18.04 a Linux distribution.

The following is a modification of the source material so you can make the installation ready for a wordpress website on apache2.

1

sudo apt-get update

1

sudo apt-get install build-essential libssl-dev libcurl4-openssl-dev libxml2-dev libjpeg-dev libpng-dev libfreetype6-dev libzip-dev

if libzip4 dependencies unmet error do:

1

sudo apt-get install ppa-purge

1

sudo ppa-purge ppa:ondrej/php

this removes the faulty repo, then purge the libzip4 installed previously (this may break other wordpress/php installations on your system)

1

sudo apt remove libzip4

1

sudo apt-get install libzip-dev

then run again

1

sudo apt-get install build-essential libssl-dev libcurl4-openssl-dev libxml2-dev libjpeg-dev libpng-dev libfreetype6-dev libzip-dev

I modified the command to use the correct modules and features from php to run a wordpress server with apache2 on an Ubuntu 18.04 based distro.

Thank you for using PHP.

If it throws a warning, its probably because some of these are already enabled by default in recent PHP versions.

Note !!! Remember to do phpenmod zip for example for any modules not active by default.

Explanation of some key options:

• --prefix: Specifies the installation directory for PHP.
• --with-apxs2: Points to the Apache apxs2 tool for building PHP as an Apache module.
• --with-config-file-path: Specifies the path to the PHP configuration file used by Apache.
• --enable-fpm: Enables PHP-FPM.
• --with-fpm-user and --with-fpm-group: Specifies the user and group for PHP-FPM.
• --with-mysqli and --with-pdo-mysql: Enable MySQL support for PHP.
• --with-openssl: Enables OpenSSL support.
• --with-curl: Enables cURL support for remote data fetching.
• --with-zlib: Enables zlib compression support.
• --with-gd, --with-jpeg, --with-freetype: Enables GD image library support.
• --with-xmlrpc: Enables XML-RPC support.
• --with-iconv: Enables iconv support for character encoding conversion.
• --enable-bcmath, --enable-mbstring, --enable-gd, --enable-zip, --enable-xml, --enable-json, --enable-exif, --enable-intl, --enable-opcache, --enable-sockets, --enable-soap: Enable various PHP extensions commonly used by WordPress.
• --disable-cgi: Disables CGI mode.

Please note that this list is a general guideline, and your specific requirements might vary based on your WordPress theme, plugins, and server setup. Always refer to the official PHP documentation and test thoroughly after making changes.

After this you can resume the guide at the beginning, just have in mind our installation path is different, for example instead of doing

1

"export PATH=\$PATH:/opt/php/php8/bin"

we do

1

export PATH=\$PATH:/usr/local/php80/bin"

Also have in mind you might want to remove the old php installation like this

1

sudo apt purge php7.0*

For my case use, my php-fpm config files are in

1

/usr/local/php80/etc

And I’m using Apache2.
