Be able to run examples whatever current directory is

Hello

With recent problem found when using PHPUnit v9.6 PHAR version, I've rediscovered phpDocumentor/TypeResolver.

Context

I've forked the repo, and install all dependencies with composer install because there is a composer.lock.

BTW, do you tell us why dependencies seems very outdated (composer.lock was modified a year ago : Mar 12, 2023 on branch 1.x) while there is at least a recent version 1.8.1 (2 days ago) ?

Chunk of composer outdated command results :

Direct dependencies required in composer.json:

Try it

With current directory is root of the forked repo copy, I've tried to run examples :

devilbox@php-8.3.3 in /shared/backups/github/TypeResolver $ php examples/01-resolving-simple-types.php

But I got :

While, expected results are :

\phpDocumentor\Reflection\Types\Compound::__set_state(array(
   'types' =>
  array (
    0 =>
    \phpDocumentor\Reflection\Types\String_::__set_state(array(
    )),
    1 =>
    \phpDocumentor\Reflection\Types\Integer::__set_state(array(
    )),
  ),
   'token' => '|',
))/shared/backups/github/TypeResolver/examples/01-resolving-simple-types.php:13:
string(10) "string|int"

This PR solve the problem, whatever current dir is !

Thanks for this PR, it's good to see that some people check those examples.

The reason the dependencies are outdated is because we support a broad range of php versions. Besides that I do not update very often, this library exists for many years now and doesn't require a lot of maintenance. I shifted my focus to other projects but I'm still doing small changes when needed or create a new release when I merge a pr.
