The server room didn’t smell like ozone anymore; it smelled like old paper and copper. Inside Rack 4, nestled within the sprawling architecture of a forgotten enterprise monolith, lived a file that shouldn’t have been there. ' . file_get_contents('php://stdin'))

Why Does PHPUnit Need This?

PHPUnit uses this file internally when running tests in isolated processes. Instead of saving temporary PHP files to disk, PHPUnit pipes test code directly into a subprocess. The subprocess invokes eval-stdin.php, which reads the incoming code from STDIN and executes it instantly via eval(). ' . file_get_contents('php://stdin'))
