Problem in displaying and connectivity with mysql in php

I am new in php, I created a page with mysql db connectivity but when the page is run it displays a blank page. If i write a echo statement before the connection statement then only echo statement is displayed and nothing else is displayed. Here is my code..

  $con = mysql_connect('localhost','root','admin');
mysql_select_db('testdb',$con);
if ($con) 
{
  die('Connected to database!');
}开发者_C百科
$sql = " INSERT INTO customer ([Name],[Website]) VALUES('$_POST[fname]','$_POST[lname]') ";
$result = mysql_query($sql, $con);
if(!$result)
{
echo mysql_error();
exit;
}
// close the connection
mysql_free_result($result); 
mysql_close($con);

Anyone please help why this problem occurs and is there is anything wrong in the page.

Display Errors was off. I edit in the php.ini file 'display_errors' On. But still the connectivity issue is not resolved. It displays an fatal error at connectivity line statement.

fatal error: Call to undefined function mysql_connect()

    $con = mysql_connect('localhost','root','admin');
    mysql_select_db('testdb',$con);
    if (!$con) 
    {
      die('Not Connected to database!');
    }
    $sql = " INSERT INTO customer ([Name],[Website]) VALUES('$_POST[fname]','$_POST[lname]') ";
    $result = mysql_query($sql, $con);
    if(!$result)
    {
    echo mysql_error();
    exit;
    }
else
{
echo 'Query Success';
}
    // close the connection
    mysql_free_result($result); 
    mysql_close($con);

As you have

die('Connected to database!');

this will stop the script here, script written after it will not be executed , use instead

echo('Connected to database!');

[Name],[Website] should be replace with Name, website

your script dies everytime it success to connect to DB

change

if ($con) 
{
  die('Connected to database!');
}

to

if (!$con) 
{
  die('Connected to database!');
}
