Performant APIs with GraphQL and PHP
summary
Shows how a PHP server serves a single /graphql endpoint using webonyx/graphql-php to parse, validate and execute queries; builds a demo API (tutorial on GitHub/Glitch) that returns exactly the requested JSON shape and supports typed schemas. Addresses the n+1 problem with deferred resolvers and batching, recommends client libraries like Apollo or Lokka, explains persisted queries, tooling (Playground, Voyager, codegen) and limits (complexity/depth, no PHP subscriptions).
