Installing PHP on Debian

Installing PHP on Debian generally uses apt packages for CLI, FPM and required extensions.

What It Does

Installing PHP on Debian generally uses apt packages for CLI, FPM and required extensions. The following examples distinguish a normal use case, a boundary case and a practical application.

Requirements and Compatibility

A supported operating-system release and suitable package repositories; package versions and names vary by release.

The code focuses on the core concept. Production implementation may also need routes, validation, persistence, authorization or deployment tooling.

Example 1: Basic Behavior

Use these commands after installing PHP through your distribution package manager.

php -v
php -m
php --ini

This is a command-line example; use it in its appropriate file or shell, not in the PHP source editor.

Example 2: Another Case

On Debian/Ubuntu, install packages appropriate to the target OS version. Names can differ by release.

sudo apt update
sudo apt install php-cli php-mbstring php-xml php-curl

This is a command-line example; use it in its appropriate file or shell, not in the PHP source editor.

Practical Example: Putting It to Use

Verify the runtime actually executing your script; CLI and PHP-FPM may have different configuration.

<?php
echo PHP_VERSION . ' ' . PHP_SAPI;

Important Behavior and Edge Cases

Exact package names and supported versions depend on the Debian release and repository.
