PHP 7 - Session Options
From PHP7+, session_start() function accepts an array of options to override the session configuration directives set in php.ini. These options supports session.lazy_write, which is by default on and causes PHP to overwrite any session file if the session data has changed.
Another option added is read_and_close, which indicates that the session data should be read and then the session should immediately be closed unchanged. For example, Set session.cache_limiter to private and set the flag to close the session immediately after reading it, using the following code snippet.
<?php
session_start([
'cache_limiter' => 'private',
'read_and_close' => true,
]);
?>
