PHP secure connection

Establish a secure connectivity to web server using PHP? how It is?

I Think that, you ask, How we establish connection php with database, because on localhost don't need for external connection Just see them,
and if am wrong way, then please mention proper query, I'll solve them.


<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
if (mysql_query("CREATE DATABASE db_name",$con))
{
echo "Database created";
}
else
{
echo "Error creating database: " . mysql_error();
}

mysql_select_db("db_table_name", $con);
$sql = "CREATE TABLE sample_table
(
FirstName varchar(15) NOT NULL,
LastName varchar(15) NOT NULL,
)";
mysql_query($sql,$con);
mysql_close($con);
?>

Or if you trying to have PHP read files on the server, u need fopen and CHMOD settings

OR Secure Connect SSL certificate (Example used when making payments)
