I want to set output_buffering=0 in a single directory. When I create a .user.ini file in that directory with output_buffering=0 , phpinfo() shows 0 for the the local value, and 4096 for the master, but the actual behavior PHP exhibits is as if output_buffering=4096.

In other words, PHP appears to be ignoring the local value and instead using the master value.

This response should arrive in three chunks, one second apart each - with or without the str_repeat(…) call. In actuality it only does so when str_repeat(…) is uncommented. When I set the master value of output_buffering=0 I get the behavior I want without str_repeat(…), but not when I set the local value.

header('Content-Type: text/text');
for ($i = 0; $i < 3; ++$i) {
  echo $i;
  // echo str_repeat(' ', 4094);
  echo "\n";
  flush();
  sleep(1);
}

According to the PHP documentation for output_buffering output_buffering is modifiable per directory.

Interestingly, despite the setting in .user.ini affecting the displayed local value, phpinfo(), does not show .user.ini in "additional .ini files parsed"

Apache is configured to use PHP-FPM with SetHandler, not ProxyPass:

<FilesMatch \.(php|phar)$>
    SetHandler "proxy:unix:/run/php-fpm/www.sock|fcgi://localhost"
</FilesMatch>
