Description

php-ze-ph module templates use {{description}} variable in api.mustache to provide description for each operation. However this description won't be available in template, since guard {{#description}} does not twig:

{{#description}}
     * {{description}}
{{/description}}

Command line used for generation

npx openapi-generator generate -Dapis='/example_item' -i spec/openapi/api-v1.yml -g php-ze-ph -o .

Steps to reproduce

• Create /example_item path operation with a summary and description
• Run above command line
• Open src/App/Handler/ExampleItem.php file
• You will see pasted summary but not description in generated PHP code. Below Add new example item should be Adds example item to the system

/**
 * @PHA\Route(pattern="/example_item")
 */
class ExampleItem
{
    /**
     * Add new example item
     * @PHA\Post()
     * TODO check if consumer is valid, if it has correct priority and if it can be moved to class annotation
     * @PHA\Consumer(name=PHConsumer\Json::class, mediaType="application/json")
     * @PHA\Attribute(name=PHAttribute\Transfer::class, options={"type":\App\DTO\ExampleItem::class,"objectAttr":"bodyData"})
     * TODO check if producer is valid, if it has correct priority and if it can be moved to class annotation
     * @PHA\Producer(name=PHProducer\Transfer::class, mediaType="application/json")
     * @param ServerRequestInterface $request
     *
     * @throws PHException\HttpCode 501 if the method is not implemented
     *
     * @return \App\DTO\ExampleItem
     */
    public function addExampleItem(ServerRequestInterface $request): \App\DTO\ExampleItem
    {
        //TODO implement method
        /** @var \App\DTO\ExampleItem $bodyData */
        $bodyData = $request->getAttribute("bodyData");
        throw new PHException\HttpCode(501, "Not implemented");
    }

Suggest a fix

Start with modules/openapi-generator/src/main/resources/php-ze-ph/api.mustache and compare the summary and description guards used for each operation. Regenerate the supplied OpenAPI example with the shown php-ze-ph command, then verify that src/App/Handler/ExampleItem.php includes “Adds example item to the system” beneath the summary.
