Article overview

How to Use Docker With PHP: Complete Local Development Setup Guide is the kind of topic that looks simple until it reaches production. Teams usually discover the real cost late: unclear boundaries, weak defaults, hidden maintenance work, and decisions that seemed harmless when the codebase was small.

The problem gets worse when the article, tutorial, or implementation guide only explains the happy path. This guide closes that gap with a practical framework, a comparison table, common mistakes, and a deep technical section you can use while planning real work.

Keep reading for the non-obvious part: the safest implementation is rarely the most impressive-looking one. It is the one your team can debug, test, document, and evolve without turning every future change into archaeology.

Key Takeaways

• How to Use Docker With PHP: Complete Local Development Setup Guide should be evaluated as a production decision, not only as a syntax or tooling choice.
• The best implementation keeps responsibilities visible, with clear ownership, tests, documentation, and rollback paths.
• Search visibility improves when practical depth, structured answers, and expert examples live on the same page.

What How to Use Docker With PHP: Complete Local Development Setup Guide means

How to Use Docker With PHP: Complete Local Development Setup Guide means applying tooling knowledge to a concrete engineering decision, then turning that decision into reliable code, documentation, and operational behavior. In practice, it combines the topic's core concepts with trade-off analysis, implementation boundaries, testing strategy, and maintenance discipline.

This is the definition worth optimizing for featured snippets because it avoids hype. It tells the reader what the topic does and what a professional implementation must include.

Why it matters now

The technical web is more crowded than it was a few years ago. Thin tutorials can still get indexed, but they rarely earn trust from senior developers, buyers, AI answer systems, or teams that need production guidance.

For tooling topics, the strongest content now has three layers:

• a clear answer for fast scanning
• a practical framework for implementation
• expert context that explains what breaks later

That same structure helps search engines understand the page. It also helps readers decide whether the advice fits their project.

Implementation framework

Use this framework before adopting the approach described in this article.

1. Define the user problem and the production risk.
2. Identify the smallest reliable implementation boundary.
3. Keep configuration, secrets, and environment-specific behavior outside the article's core logic.
4. Add tests for the behavior that would hurt if it regressed.
5. Document the trade-off, not only the final code.
6. Measure the result with logs, metrics, or user-facing outcomes.
7. Revisit the decision after real usage exposes edge cases.

The sequence is deliberately conservative. It keeps the work grounded in outcomes instead of novelty.

Practical comparison

This table is intentionally practical. It gives a reviewer something to check before the implementation becomes expensive to change.

Expert workflow

Expert tip: "Treat How to Use Docker With PHP: Complete Local Development Setup Guide as a system boundary. If the next developer cannot find where the decision lives, how it is tested, and when it should be avoided, the implementation is not finished."

A useful workflow is simple:

• Start with the smallest working example.
• Add the constraints that exist in your real project.
• Remove anything that only demonstrates cleverness.
• Write down the failure modes.
• Add links to related decisions so future readers can navigate the topic cluster.

That last point matters for both humans and search systems. A single article can answer a question; a cluster proves authority.

Common mistakes

Mistake 1: Copying a pattern without its context

A pattern that works in a small demo can fail in a real application. The missing context is usually data volume, team experience, deployment process, security requirements, or observability.

Before copying the pattern, ask what assumption made it safe in the original example.

Mistake 2: Putting business logic in the wrong layer

This is the fastest way to make future debugging expensive. In Laravel, PHP, and server-rendered websites, presentation should receive prepared data, not discover rules on its own.

Keep decision logic in models, actions, services, policies, requests, jobs, or documented helpers where it can be tested directly.

Mistake 3: Optimizing for novelty instead of maintainability

Newer tools and language features can be valuable. They can also hide simple behavior behind unfamiliar syntax.

Use the option that makes the next production incident easier to understand.

Mistake 4: Publishing without a measurement plan

If the article describes a performance, SEO, security, or architecture improvement, define how success will be checked. Logs, tests, crawl diagnostics, analytics, and user behavior are all stronger than assumptions.

Original Technical Deep Dive

What Docker should solve

Docker is not there to make a PHP project more fashionable. It is there to remove local machine drift.

Without Docker, one developer has PHP 7.4, another has PHP 8.0, one has MySQL 5.7, one has MySQL 8, and somebody has an old extension installed globally that hides a missing dependency. The project works, but only on the machine where it was accidentally assembled.

A useful Docker setup gives the team:

• One PHP runtime version.
• One MySQL version.
• One Nginx configuration.
• Repeatable extension installation.
• A clean way to run Composer, migrations, and tests.
• Persistent database data without installing MySQL on the host.

The goal is not to containerize everything at once. Start with the local web stack: Nginx, PHP-FPM, and MySQL.

Target structure

Use a small structure that keeps Docker files visible but separate from application code:

project/
  app/
  public/
    index.php
  docker/
    nginx/
      default.conf
    php/
      Dockerfile
      php.ini
  compose.yaml
  composer.json
  .dockerignore
  .env

In 2020, most projects called the Compose file docker-compose.yml and used docker-compose up. Modern Docker uses compose.yaml and docker compose up. The service layout is the same. Use the command style your team has installed.

Create the PHP-FPM image

Create docker/php/Dockerfile:

FROM php:7.4-fpm

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
        git \
        unzip \
        libzip-dev \
    && docker-php-ext-install \
        pdo \
        pdo_mysql \
        zip \
    && rm -rf /var/lib/apt/lists/*

COPY --from=composer:1.10 /usr/bin/composer /usr/bin/composer

WORKDIR /var/www/html

For a 2020 app, php:7.4-fpm was a normal choice. For a new project, use the current supported PHP-FPM tag your production runtime actually runs.

Do not use php:latest. Pin the version. Local development should fail in the same way for everyone.

Add php.ini

Create docker/php/php.ini:

display_errors=1
display_startup_errors=1
error_reporting=E_ALL
memory_limit=512M
upload_max_filesize=20M
post_max_size=20M
date.timezone=UTC

Then copy it from the Dockerfile:

COPY docker/php/php.ini /usr/local/etc/php/conf.d/local.ini

Keep local settings explicit. If production uses a different php.ini, that is fine. The point is to avoid hidden global settings on developer laptops.

Configure Nginx

Create docker/nginx/default.conf:

server {
    listen 80;
    server_name localhost;

    root /var/www/html/public;
    index index.php index.html;

    location / {
        try_files $uri /index.php$is_args$args;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location ~ /\. {
        deny all;
    }
}

The important line is:

fastcgi_pass php:9000;

php is the Compose service name. Compose puts the services on a shared network, so Nginx can reach PHP-FPM by that name.

The root points to public/, not the project root. Do not expose .env, vendor/, storage files, or application internals through Nginx.

Write the Compose file

Create compose.yaml:

services:
  nginx:
    image: nginx:1.19-alpine
    ports:
      - "8080:80"
    volumes:
      - ./:/var/www/html:ro
      - ./docker/nginx/default.conf:/etc/nginx/conf.d/default.conf:ro
    depends_on:
      - php

  php:
    build:
      context: .
      dockerfile: docker/php/Dockerfile
    volumes:
      - ./:/var/www/html
    environment:
      APP_ENV: local
      DB_HOST: mysql
      DB_DATABASE: app
      DB_USERNAME: app
      DB_PASSWORD: secret
    depends_on:
      - mysql

  mysql:
    image: mysql:8.0
    command: --default-authentication-plugin=mysql_native_password
    ports:
      - "33060:3306"
    environment:
      MYSQL_DATABASE: app
      MYSQL_USER: app
      MYSQL_PASSWORD: secret
      MYSQL_ROOT_PASSWORD: root-secret
    volumes:
      - mysql-data:/var/lib/mysql
    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-h", "localhost", "-psecret"]
      interval: 5s
      timeout: 3s
      retries: 20

volumes:
  mysql-data:

If your team is using old Compose in 2020 style, this equivalent header is common:

version: "3.8"
services:
  # same services here

Modern Compose no longer needs the top-level version, because the Compose Specification replaced the old 2.x and 3.x split.

Understand the three services

nginx receives browser traffic on localhost:8080, serves static files from public/, and forwards PHP scripts to PHP-FPM.

php runs the application code. It has Composer, PHP extensions, and the same source tree mounted into /var/www/html.

mysql runs the database. Its data lives in the named Docker volume mysql-data, not inside the disposable container layer.

From the host machine, connect to MySQL on:

127.0.0.1:33060

From PHP inside Compose, connect to:

mysql:3306

Do not use localhost from the PHP container when connecting to MySQL. Inside a container, localhost means that same container.

Add a .dockerignore

Create .dockerignore:

.git
vendor
node_modules
storage/logs
docker/mysql/data

The build context should not include dependencies, Git history, logs, or local database files. Keep images smaller and builds more predictable.

Add a smoke-test app

Create public/index.php:

<?php

declare(strict_types=1);

$pdo = new PDO(
    sprintf(
        'mysql:host=%s;dbname=%s;charset=utf8mb4',
        getenv('DB_HOST'),
        getenv('DB_DATABASE')
    ),
    getenv('DB_USERNAME'),
    getenv('DB_PASSWORD'),
    [
        PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
    ]
);

echo 'PHP ' . PHP_VERSION . ' connected to MySQL.';

This is not application architecture. It is a smoke test. Once the stack works, move database code into your normal application layer.

Start the stack

Build and start:

docker compose up --build

Open:

http://localhost:8080

Run Composer inside the PHP container:

docker compose run --rm php composer install

Open a shell:

docker compose exec php bash

View logs:

docker compose logs -f nginx php mysql

Stop containers:

docker compose down

Stop containers and remove the MySQL volume:

docker compose down -v

Use down -v only when you intentionally want to delete the local database.

Add Composer scripts

Make common commands boring:

{
    "scripts": {
        "docker:up": "docker compose up --build",
        "docker:down": "docker compose down",
        "docker:shell": "docker compose exec php bash",
        "test": "phpunit"
    }
}

You can run:

composer docker:up

Do not hide everything behind scripts, but do document the commands the team should use every day.

Handle database readiness

depends_on starts services in order, but your application still needs to survive MySQL taking a few seconds to initialize.

Good options:

• Add retry logic in the application bootstrap or migration command.
• Run migrations after mysql is healthy.
• Use a small wait script for local development only.

Do not build fragile startup flows where PHP exits forever because MySQL was not ready on the first attempt.

Run migrations

For a framework app, run migrations inside the PHP container:

docker compose exec php php artisan migrate

For a plain PHP app, use your own migration command:

docker compose exec php php bin/migrate.php

[IMAGE: Supporting visual 2 for How to Use Docker With PHP: Complete Local Development Setup Guide, showing How to Use Docker With PHP: Complete Local Development Setup Guide decisions, examples, and Docker, PHP, PHP-FPM. Alt: How to Use Docker With PHP: Complete Local Development Setup Guide how-to-use-docker-with-php-local-development-setup visual 2]

The migration code should read:

DB_HOST=mysql
DB_DATABASE=app
DB_USERNAME=app
DB_PASSWORD=secret

The service name is the database host.

File permissions

On macOS and Windows with Docker Desktop, bind mounts are usually workable. On Linux, files created inside the container can become owned by root or www-data, depending on the image and process.

If that becomes painful, standardize one of these:

Alt: How to Use Docker With PHP: Complete Local Development Setup Guide how-to-use-docker-with-php-local-development-setup visual 2]

• Run development commands with a matching user ID.
• Keep writable app directories owned by the web user inside the container.
• Mount only source code and use named volumes for generated dependency folders.

Do not make the whole project 777. That hides the problem and creates worse habits.

Do not copy vendor during local development

For local development, bind-mount the project and run composer install in the container. That keeps dependencies aligned with the container PHP version.

For production images, the strategy is different:

• Install Composer dependencies during build.
• Do not bind-mount source code.
• Use a production php.ini.
• Disable display_errors.
• Build assets in a separate stage.
• Run as a non-root user where practical.

Local Docker and production Docker have different goals. Local optimizes feedback. Production optimizes immutability, security, and repeatability.

Common failures

SQLSTATE[HY000] [2002] Connection refused

PHP tried to connect before MySQL was ready, or DB_HOST is wrong. Inside Compose, use mysql, not localhost.

Primary script unknown

Nginx and PHP-FPM disagree about the file path. Make sure both services mount the project at the same container path, and make sure SCRIPT_FILENAME resolves to the PHP file inside the PHP container.

Class PDO not found or missing driver errors

The PHP image is missing the extension. Install pdo_mysql with docker-php-ext-install, rebuild the image, and restart.

docker compose build --no-cache php
docker compose up

Changes to php.ini do not apply

Rebuild or restart the PHP service:

docker compose restart php

MySQL data will not reset

The named volume still exists. Remove it intentionally:

docker compose down -v

• docker compose up --build starts the full stack.
• http://localhost:8080 reaches Nginx.
• PHP requests execute through PHP-FPM.
• PHP can connect to MySQL using host mysql.
• MySQL data survives container recreation.
• composer install runs inside the PHP container.
• Tests run inside the PHP container.
• .env values match container hostnames, not host-machine assumptions.
• The project README documents the daily commands.
• Developers do not need to install PHP, Nginx, or MySQL directly on the host.

That is the value of Docker for PHP development: fewer local mysteries, fewer setup documents, and a runtime that is close enough to production to catch real mistakes early.
