what is $GLOBALS["___mysqli_ston"] in mysqli

Question

I am trying to use mysqli first time. I have a question, what is $GLOBALS["___mysqli_ston"] ? Can you plz tell me. I am not getting any direct answer when googling

Answer 1

MySQLConverter assumes that this global variable is set to equal your DB connection object; if the converter finds a mysql_connect it will (partially, but with a warning) convert your code into code that includes an assignment of $GLOBALS["___mysqli_ston"] to the result of the mysqli_connect function something like this:

$link=($GLOBALS["___mysqli_ston"] = mysqli_connect($hostname, $username, $pwd));
