session start Options

Starting with PHP Sessions we can pass an array with session-based php.ini options to the session_start function.

Example

<?php
   if (version_compare(PHP_VERSION, '7.0.0') >= 0) {
       // php >= 7 version
       session_start([
          'cache_limiter' => 'private',
          'read_and_close' => true,
       ]);
   } else {
       // php < 7 version
       session_start();
   }
?>

This feature also introduces a new php.ini setting named session.lazy_write, which defaults to true and means that session data is only rewritten, if it changes.
