Answer 1

if you want to find datadir in linux or windows you can do following command

mysql -uUSER -p -e 'SHOW VARIABLES WHERE Variable_Name = "datadir"'

if you are interested to find datadir you can use grep & awk command

mysql -uUSER -p -e 'SHOW VARIABLES WHERE Variable_Name = "datadir"' | grep 'datadir' | awk '{print $2}'

Answer 2

public function variables($variable="")
{
  return empty($variable) ? mysql_query("SHOW VARIABLES") : mysql_query("SELECT @@$variable");
}

/*get datadir*/
$res = variables("datadir");

/*or get all variables*/
$res = variables();
