Function generate_php_graphql 

pub fn generate_php_graphql(schema: &str, target: &str) -> Result<String>

Generate PHP GraphQL code from a schema

Parses the GraphQL schema string and generates complete PHP code with type definitions, resolver implementations, and schema configuration based on the target specification. Generated code uses PSR-4 namespacing, strict_types declarations, typed properties, and webonyx/graphql-php library for schema binding.

Arguments

• schema - GraphQL schema as a string (SDL format)
• target - Generation target: “all” (complete), “types” (types only), “resolvers” (resolver classes), or “schema” (schema definition)

Returns

Generated PHP code as a string with:

• <?php opening tag and declare(strict_types=1);
• PSR-4 namespace declaration under GraphQL namespace
• Class definitions for object types, input types, and enums (PHP 8.1+)
• Typed properties with appropriate nullability markers
• Resolver method signatures with return type declarations
• Or an error if parsing/generation fails

Examples

let schema = r#"
type Query {
  user(id: ID!): User
}
type User {
  id: ID!
  name: String!
}
"#;
let code = generate_php_graphql(schema, "all")?;
println!("{}", code);
