Installing PHP with a Package Manager

Package-manager installation keeps PHP updates and dependencies tracked by the operating system.

What It Does

Package-manager installation keeps PHP updates and dependencies tracked by the operating system. 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

Package-manager commands are distribution-specific; avoid mixing package ecosystems.

<?php
$cmds = ['apt' => 'apt install php-cli', 'dnf' => 'dnf install php-cli'];
echo implode(' OR ', $cmds);

Important Behavior and Edge Cases

Repository versions may differ from the latest upstream PHP release.

Key Takeaways

• Package-manager installation keeps PHP updates and dependencies tracked by the operating system.
• Repository versions may differ from the latest upstream PHP release.
• Check security support, package origin and PHP module versions.

Before adapting these examples, verify the return values, test the failure paths and confirm that your application meets its security and environment requirements.
