PHP

PHP is a popular general-purpose scripting language that is especially suited to web development.

Requirements

• For Debian, use Sury PHP.
• For Ubuntu, use Ondřej Surý.

Debian

sudo apt update -y
sudo apt -y install lsb-release ca-certificates curl
sudo curl -sSL -o /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
sudo sh -c 'echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list'
sudo apt update -y

Ubuntu

sudo add-apt-repository ppa:ondrej/php
sudo apt update -y

Install PHP

Here, PHP 8.2 is used as an example. You can replace it with the version you want.

INFO

This guide uses fpm as the PHP handler to use with NGINX.

sudo apt -y install php8.2-fpm

Install extensions

Here are some common PHP extensions:

sudo apt install -y php8.2-mbstring
sudo apt install -y php8.2-mysql
sudo apt install -y php8.2-common php8.2-cli php8.2-dev
sudo apt install -y php8.2-xml
sudo apt install -y php8.2-curl
sudo apt install -y php8.2-gd php8.2-imagick
sudo apt install -y php8.2-imap
sudo apt install -y php8.2-opcache
sudo apt install -y php8.2-soap
sudo apt install -y php8.2-zip php8.2-bz2
sudo apt install -y php8.2-intl

Fix PHP-FPM owner

If you use NGINX, you need to change the PHP-FPM owner to nginx. You have to change the owner in the PHP-FPM configuration file for each PHP version you have installed.

sudo sed -i 's/www-data/nginx/' /etc/php/8.2/fpm/pool.d/www.conf

Restart PHP-FPM:

sudo systemctl restart php8.2-fpm

Usage

Specific PHP version

If you installed multiple PHP versions, you can use a specific version by specifying the version number.

php8.2 -v

PHP version

To see the current PHP version, run the following command:

php -v

You can change current version with Switch PHP

PHP modules

php -m

Specific module

php -m | grep <module>

Example:

php -m | grep curl

If you see curl in the output, it means the curl module is installed.

Switch PHP

To switch PHP versions, use the following command:

sudo update-alternatives --config php

Composer

Use command line instructions of Composer website to download and install latest version of Composer

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php
php -r "unlink('composer-setup.php');"

You have just to copy installation instructions and composer will be download, this is an example:

sudo mv composer.phar /usr/local/bin/composer
sudo chown -R $USER ~/.config/composer/

Global package

To install global package like laravel

INFO

This is an example, you can replace laravel with any package you want.

composer global require laravel/installer

Add this to .zshrc

vim ~/.zshrc

export PATH=~/.config/composer/vendor/bin:$PATH

source ~/.zshrc

Now you can use composer.
