Overridden ini values are ignored when php.ini uses section headers

[Emosewaj]

As of right now, Runtime::getCurrentSettings() parses php.ini files respecting section headers using the optional $process_sections parameter of parse_ini_file(), however, these section headers are then later ignored when comparing the ini file's values to the value retrieved by ini_get(). This erroneously causes some ini values that have been overridden via the command line to be ignored and don't get passed through if they either don't exist in the ini file or are under a section header:

; php.ini
[xdebug]
xdebug.mode=debug

$config = parse_ini_file($ini, true) results in

array(1) {
  'xdebug' =>
  array(1) {
    'xdebug.mode' =>
    string(5) "debug"
  }
}

$config = parse_ini_file($ini) results in

array(1) {
  'xdebug.mode' =>
  string(5) "debug"
}

Additionally, I believe
if (isset($config[$value]) && $set != $config[$value])
should be changed to
if (!isset($config[$value]) || $set != $config[$value])
as otherwise, values not set in php.ini but set through the command line would also not be passed through.

Was this fixed by #63?

It was, I'm no longer encountering this issue on 5.1.4.
