What is PHP Deployment?

PHP deployment is the process of moving a PHP application from a local development environment to a production server, ensuring it runs securely, efficiently, and reliably for end users.

Why Deployment Matters

• Makes application publicly accessible

• Ensures performance & security

• Reduces downtime

• Enables scaling

• Supports updates & bug fixes

Pre-Deployment Checklist

• Remove debug code

• Optimize performance

• Secure environment variables

• Configure production settings

• Run tests

Server Requirements

• PHP (latest stable version)

• Web server (Apache / Nginx)

• Database (MySQL / PostgreSQL)

• Composer

• SSL certificate

Deployment Environments

• Development

• Staging

• Production

Uploading PHP Application

Using FTP/SFTP

• FileZilla

• WinSCP

Using Git

git clone https://github.com/user/repo.git

Environment Configuration

Use .env file for configuration.

APP_ENV=production
DB_HOST=localhost

Composer in Production

composer install --no-dev --optimize-autoloader

File & Folder Permissions

chmod -R 755 storage
chmod -R 644 *.php

Apache Configuration

DocumentRoot /var/www/html/public

Enable .htaccess:

AllowOverride All

Nginx Configuration

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

PHP Configuration (php.ini)

display_errors = Off
memory_limit = 256M
max_execution_time = 30

Database Migration

• Run migration scripts

• Backup database before deployment

Enable OPcache

opcache.enable=1
opcache.memory_consumption=128

Security Best Practices

• Disable directory listing

• Use HTTPS

• Hide sensitive files

• Secure file uploads

• Restrict permissions

Zero Downtime Deployment

• Use symlinks

• Blue-green deployment

• Load balancers

CI/CD Deployment

Tools:

• GitHub Actions

• GitLab CI

• Jenkins

Docker Deployment (Optional)

docker-compose up -d

Monitoring & Logging

• Error logs

• Server monitoring

• Application logs

Common Deployment Issues

• Missing extensions

• Permission errors

• Incorrect environment variables

• Cache issues
