php-openapi-generator

Configuration Reference

This page covers the most important options in php-openapi-generator.php.

Core Inputs

• $config->specFile (default: openapi.yaml)
• $config->outputDir (default: generated)
• $config->phpVersion (default: 8.2)

Namespaces and Output Directories

• $config->modelNamespace (default: Generated\\Model)
• $config->modelOutputDir (default: Model)
• $config->apiNamespace (default: empty)
• $config->apiOutputDir (default: empty)

Server vs Client Generation

• $config->generationTarget = GenerationTarget::Server|Client
• $config->frameworkTarget = FrameworkTarget::None|Symfony|Laravel (server mode)
• $config->frameworkVersion = '8.0'|'9.0'|'10.0'|'11.0'|... (optional, server mode)
• $config->httpClient = HttpClientAdapter::SymfonyHttpClient|Guzzle|Psr18 (client mode)
• $config->httpClientVersion = '6.4'|'7.0'|'7.8'|... (optional, client mode)

frameworkVersion and httpClientVersion are optional string values you can set when generated code must react to framework- or transport-specific breaking changes. They are intended for template selection and conditional generation logic, similar to how $config->phpVersion is already used for PHP-specific output.

Model Generation Options

• $config->generateConstructor (default: true)
• $config->phpReadonly (default: true)
• $config->generatePhpDoc (default: true)
• $config->generateFromArray (default: true)
• $config->generateToArray (default: true)
• $config->omitNullsInToArray (default: true)
• $config->splitReadWriteDtos (default: false)

Type and Naming Controls

• $config->dateTimeClass (default: DateTimeImmutable::class)
• $config->dateClass (default: DateTimeImmutable::class)
• $config->typeMapping (default: [])
• $config->propertyNaming (default: PropertyNaming::CamelCase)
• $config->classPrefix, $config->classSuffix
• $config->interfaceSuffix, $config->enumSuffix
• $config->reservedWordSuffix (default: _)

Validation Controls

• $config->validationStrategy (ValidationStrategy::None|SymfonyConstraints|NativeMethod|LaravelValidation)
• $config->validateServerRequest
• $config->validateServerResponse
• $config->validateClientRequest
• $config->validateClientResponse

These four flags inject runtime validation calls in generated server/client API classes when validationStrategy is ValidationStrategy::NativeMethod, ValidationStrategy::SymfonyConstraints, or ValidationStrategy::LaravelValidation.

See Validation Strategies for behavior and recommended defaults.

Operation Filtering

Generate only selected operations and their reachable schema graph:

• $config->includeTags, $config->excludeTags
• $config->includeOperationIds, $config->excludeOperationIds
• $config->includePaths, $config->excludePaths

Plugin and Runtime Controls

• $config->autoGenerate (run on Composer hook)
• $config->addPlugin (enable plugin hook integration)
• $config->verbosePluginWarnings
• $config->typedErrorResponses
• $config->generateSecuritySchemes

For x-* extension usage and custom plugin hooks, see Extension Plugins.

Example Config

<?php

declare(strict_types=1);

use MaxBeckers\OpenApiGenerator\Config\FrameworkTarget;
use MaxBeckers\OpenApiGenerator\Config\GenerationTarget;
use MaxBeckers\OpenApiGenerator\Config\GeneratorConfig;
use MaxBeckers\OpenApiGenerator\Config\HttpClientAdapter;
use MaxBeckers\OpenApiGenerator\Config\ValidationStrategy;

$config = new GeneratorConfig();

$config->specFile = 'openapi.yaml';
$config->outputDir = 'generated';

$config->modelNamespace = 'App\\Model';
$config->apiNamespace = 'App\\Api';

$config->generationTarget = GenerationTarget::Server;
$config->frameworkTarget = FrameworkTarget::Symfony;
$config->frameworkVersion = '8.0';

$config->phpReadonly = true;
$config->validationStrategy = ValidationStrategy::SymfonyConstraints;
$config->validateServerRequest = true;

// Client-only example when generating HTTP clients instead of server glue:
// $config->generationTarget = GenerationTarget::Client;
// $config->httpClient = HttpClientAdapter::Guzzle;
// $config->httpClientVersion = '7.8';

$config->includeTags = ['pets'];
$config->excludeOperationIds = ['deletePet'];

return $config;

CLI Overrides
