Deploy your PHP app to Fly.io
Step-by-step deployment help for PHP apps on Fly.io. We fix PHP-specific deployment issues, configure Fly.io, and get your app live. From $19.
PHP issues we fix before deploying
Common PHP problems that affect Fly.io deployments.
SQL injection vulnerabilities
Direct variable interpolation in SQL queries instead of prepared statements or query builders, allowing attackers to read or modify database contents.
Cross-site scripting (XSS)
User input echoed directly into HTML without htmlspecialchars() or template engine escaping, enabling script injection attacks.
Insecure file uploads
File upload handlers that only check MIME types without validating file content, allowing PHP shell uploads and remote code execution.
Deprecated function usage
AI tools generate code using deprecated functions like mysql_query, ereg, and create_function that are removed in modern PHP versions.
Fly.io deployment issues we check for
Common Fly.io problems that break PHP apps in production.
Dockerfile missing or misconfigured
Fly.io requires a Dockerfile for deployment. AI tools that scaffold without one force flyctl to auto-generate a suboptimal Dockerfile that misses build steps.
Volume only available in a single region
Fly volumes are pinned to one region. Multi-region deployments try to access a volume that doesn't exist in other regions, causing crashes.
Machine restarts losing in-memory state
AI-generated apps store session data or caches in memory. Fly machines can restart or migrate, wiping all in-memory state without warning.
Internal DNS resolution failing between services
Services within a Fly organization communicate via <app>.internal hostnames, but AI-generated code hardcodes localhost or public URLs.

Frequently asked questions
How do I deploy a PHP app to Fly.io?
We handle PHP deployments to Fly.io end to end. Start with our code audit ($19) to identify deployment blockers specific to your PHP project, then we configure Fly.io, fix issues, and get your app live in production.
What PHP issues affect Fly.io deployments?
PHP projects commonly have sql injection vulnerabilities and cross-site scripting (xss). On Fly.io, these combine with dockerfile missing or misconfigured and volume only available in a single region to cause deployment failures.
Can SpringCode deploy my PHP project to Fly.io?
Yes. We specialize in deploying PHP applications to Fly.io. We audit your codebase for PHP-specific issues, configure Fly.io correctly, and handle the full deployment so your app runs reliably in production.
What does PHP deployment to Fly.io cost?
Our code audit ($19) identifies all Fly.io deployment blockers in your PHP project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
