Error message

Hi, I encounter an error message that I am not able to fix it. Seeking help from those expert, thanks beforehand.

<?php
$users="";
$host=“localhost”;
$password="";
$database=“kirupa”;
$connection=mysql_connect($host,$users,$password)
or die(“Couldn’t connect to server”);
$db=mysql_select_db($database,$connection)
or die(“Couldn’t connect to server”);
$query="INSERT INTO users SET;
name=“John”,location=“Tanjung Karang”,date=“CURDATE()”;
$result=mysql_query($query) or die (“Couldn’t execute query”);
echo “New name added to database<br>”;
?>

Parse error: syntax error, unexpected T_STRING in C:\xampp\htdocs\Database.php on line 11
