The Technical Equivalent of Drinking While Pregnant

Yes, it's called 'spawning a child process that invokes the PHP interpreter.' It's the technical equivalent of putting a fish in a birdcage and wondering why it won't sing

Sure, you can spawn PHP from a Node child_process and call it a “polyglot microservice” - just be ready to raise a codebase that inherits both callback-hell colic and legacy include-spaghetti tantrums

This is like asking if you can run your Kubernetes cluster inside a Docker container that's running on a VM that's hosted in another Docker container - technically possible with enough abstraction layers and child_process.exec(), but at that point you've created a Rube Goldberg machine that would make even the most patient SRE weep into their YAML files

This is the equivalent of asking 'Can I compile my Java code with the Python interpreter?' - a question that reveals a fundamental misunderstanding of runtime environments. While you *could* theoretically spawn PHP processes from Node.js via child_process.exec(), that's not 'running PHP in Node.js' any more than calling a REST API makes you a polyglot. The real tragedy is that 30 people felt compelled to explain why this violates the laws of runtime physics, when a simple 'they're different runtimes, friend' would suffice. Though honestly, after dealing with callback hell and then Promise chains and then async/await, maybe some Node developers are just looking for any excuse to switch to PHP's synchronous simplicity

Yes - just child_process.spawn('php -S') and call it “microservices”; congratulations, you’ve reinvented CGI, now with an event loop silently judging you

Sure, you can hide PHP-FPM behind Express and call it “migration” - congrats, you now own a polyglot monolith with two package managers, two runtimes, and one very tired on-call

Node devs: 'Just spawn('php', ['index.php']) - baby project's event-driven and totally unaffected.'
