The original eval-stdin.php has poor error handling. A "better" version might look like this:

<?php
// Improved version - DO NOT use in production web environments
$code = file_get_contents('php://stdin');
if ($code === false) 
    fwrite(STDERR, "Failed to read from stdin\n");
    exit(1);
try 
    eval('?>' . $code);

Running such tests in the main process would break the entire test suite. By spawning a subprocess, PHPUnit ensures that any catastrophic or state-changing behavior remains confined. eval-stdin.php is the engine that receives and executes the isolated test chunk.
