Class "Symfony\Polyfill\Php83\Php83" not found (PHPStan 2.1.27) #13545
Description
Bug report
We are bumping into an issue with PHPStan's internal dependency symfony/polyfill-php83 not managing to find the polyfill for str_increment. We are using the latest PHPStan version, combined with PHP 8.1.
It occurs when we do something like:
$str = "";
$str++;
This triggers the bit of code in MutatingScope that calls str_increment.
Here's our version info:
PHP runtime version: 8.1.33
PHP composer.json required version: 8.1-8.5.99
PHP version for analysis: 8.1.8 (from config.php in composer.json)
PHPStan version: 2.1.27
And the stacktrace we got:
Internal error: Class "Symfony\Polyfill\Php83\Php83" not found while analysing file /builds/apps/foo/src/Foo.php
