Deploying a Simple PHP Application to a Server

A minimal production deployment still needs a document root, PHP-FPM handler, TLS and private configuration.

What It Does and When to Use It

Run the relevant deployment or container command in the intended trusted environment. A build artifact contains immutable application code, while production configuration and secrets are injected at runtime.

Requirements, Inputs and Expected Behavior

Confirm the runtime, extension, environment variables, and permissions before running the examples in production. Do not expose the project root containing vendor, .env or source tools.

Example 1: Basic Operation

Run the relevant deployment or container command in the intended trusted environment.

sudo install -d -m 755 /srv/app/public && sudo install -m 644 public/index.php /srv/app/public/index.php

Example 2: Behavior and Validation

Confirm PHP version, extensions and INI paths in the target runtime.

php -v
php -m | grep -E 'pdo|openssl|mbstring'
php --ini

Practical Example: Application Use

Check actual service health and log output; adapt host and service names to deployment.

curl -fsS http://127.0.0.1/health || exit 1
sudo journalctl -n 30 --no-pager

Important Behavior and Edge Cases

The second example highlights: Confirm PHP version, extensions and INI paths in the target runtime. The practical example adds: Check actual service health and log output; adapt host and service names to deployment.

Comparison with Related Approaches

Approach	What changes
Local build and production deployment	A build artifact contains immutable application code, while production configuration and secrets are injected at runtime.
Choosing safely	Pin base images and dependencies and require a health-check before routing traffic.

Common Beginner Mistakes

Mistake	Correct approach
Assuming successful execution proves the result is usable	Check the return value, required extension, and observable output of the specific operation.
Ignoring runtime and environment differences	Verify PHP version, SAPI, operating system, service access, and permissions before deployment.
Skipping operational constraints	Do not expose the project root containing vendor, .env or source tools.

Key Takeaways
