mysql_pconnect()

mysql_pconnect() acts very much like mysql_connect() with two major differences.

First, when connecting, the function would first try to find a (persistent) link that's already open with the same host, username and password. If one is found, an identifier for it will be returned instead of opening a new connection.

Second, the connection to the SQL server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (mysql_close() will not close links established by mysql_pconnect()).

PHP stored procedure

create function Area (R double) returns double

begin
declare A double;
set A = R * R * pi();
return A;
end

And to call it from php code to display the area of a circle with radius 22cm,
$rs_area = mysql_query(“select Area(22)”);
$area = mysql_result($rs_area,0,0);
echo “The area of the circle with radius 22cm is ”.$area.” sq.cm”;
?>
