Description

Generated zend-expressice stub contains syntax errors when pattern of property ends with *.
The pattern is embedded into annotation and breaks the DocComment.

This is also reproduced in the current sample.

openapi-generator version

$ git log --oneline -n 1

Command line used for generation

$ java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate --skip-validate-spec -t modules/openapi-generator/src/main/resources/ze-ph -g php-ze-ph -o /tmp/php-ze-ph -i https://gist.githubusercontent.com/autopp/472847da6c9de80450117a9cfecbc6d1/raw/9ea6e9d6c0e3e9b724f92f2a52b76c7b42f8be29/example.yml

Steps to reproduce

1. Run the above command to generate client code for Ruby.
2. Run php -l /tmp/php-ze-ph/src/App/DTO/InlineObject.php to check syntax of the generated model code.
3. Get error in src/App/DTO/InlineObject.php

   $ php -l /tmp/php-ze-ph/src/App/DTO/InlineObject.php
   Parse error: syntax error, unexpected '"', expecting function (T_FUNCTION) or const (T_CONST) in /tmp/php-ze-ph/src/App/DTO/InlineObject.php on line 15
   Errors parsing /tmp/php-ze-ph/src/App/DTO/InlineObject.php

Suggest a fix

Sorry, I have no idea. I don't know how to escape */ in a DocComment.

Start with the PHP generator templates under modules/openapi-generator/src/main/resources/ze-ph and compare them with samples/server/openapi3/petstore/php-ze-ph/src/App/DTO/InlineObject3.php. Reproduce the issue with the documented generation command, then run php -l on the generated DTO. Done means a property pattern ending in * no longer produces a PHP syntax error in the generated DocComment.
