php - what is the role of ob_start() in here -

- 

session_start(); ob_start(); $hasdb = false; $server = 'localhost'; $user = 'user'; $pass = 'pass'; $db = 'acl_test'; $link = mysql_connect($server,$user,$pass); if (!is_resource($link)) {        $hasdb = false;     die("could not connect mysql server @ localhost."); } else {        $hasdb = true;     mysql_select_db($db); }

a) ob_start() do.? got understand turn output buffering on. reference above code benefit if use ob_start() while trying establish connection database. output data buffer?

thank you..

normally php sends text not included in <?php ... ?>, echos, prints output. send err... output: http server (which sends client), console etc.

after ob_start output saved in output buffer, can later decide it.

it doesn't affect db connection. deals text (mostly) produced php.
