Hi All,
Request your help in converting a PHP code to D equivalent
code
PHP Code:
class avmtest {
private $con;
function __construct() {
global $config;
$this->con = new mysqli(test.srv.com:3910,
testusr, xxxx#, test);
if($this->con->connect_errno) { die("Connection
Failed.\n"); }
}
function getHostname() {
$qdata = $this->con->prepare("SELECT host_name
FROM hosts_coll");
$qdata->execute();
$qdata->bind_result($host);
while($qdata->fetch()) {
$data[] = array("HostName" => $host);
}
$sdata->close();
return $data;
}
}
D Code:
module avm.test;
import mysql;
import std.array : array;
import std.conv;
import std.variant;
class avmtest
{
private conn;
auto avmconnect()
{
auto connectionStr =
"host=test.srv.com;port=3910;user=testusr;pwd=xxxx#;db=test";
Connection conn = new Connection(connectionStr);
scope(exit) conn.close();
}
auto getHostname()
{
ResultRange qdata = conn.query("SELECT host_name FROM
`hosts_coll`");
Row row = qdata.front;
Variant h = row[0];
qdata.close();
return h.to!string;
}
}
Error: Error: no identifier for declarator conn
The instance variable in the D code, `conn`, doesn't have a
type. I guess the type should be `Connection`. In the D version
of `avmconnect` you're declaring a local variable named `conn`
instead of referring to the instance variable.
