This removes any additional variable that may have been inherited from the parent process.

maybe your github.com comment should be a comment in the source for this magic sauce :)

Indeed :)

foreach ($env as $env_var => $env_val) {
if (strval($env_val) === '') {
// proc_open does not pass empty env vars

proc_open does not pass empty env vars, so if we export empty env vars here, the test will see these vars when running with the .sh file, but not when running it via run-tests.php.

$env_lines[] = "export $env_var=" . escapeshellarg($env_val ?? "");
}
$exported_environment = "\n" . implode("\n", $env_lines) . "\n";
