Question

I’m trying to connect to Mysql database with following Php code. But I get 2 error message.

Mysql Connect Code:

<?php
define("HOST", "localhost" );
define("USER", "root");
define("PASS", "");
define("DB", "classified");

mysql_connect("HOST", "USER") or die("Cannot connect to database");;
mysql_select_db("DB") or die("Cannot connect to select db");
?>

Error Message:

Warning: mysql_connect(): php_network_getaddresses: getaddrinfo failed: No such host   
is known. in D:\Software\Installed\xampp\htdocs\Classified-website\toplevel\content
\database\databd.php on line 7

Warning: mysql_connect(): php_network_getaddresses: getaddrinfo failed: No such host 
is known. in D:\Software\Installed\xampp\htdocs\Classified-website\toplevel\content
\database\databd.php on line 7

Cannot connect to database.

Why I get this 2 error message. If i use without define function then it’s working. BUT..

Answer 1

Remove the quotes from
mysql_connect("HOST", "USER")

To
mysql_connect(HOST, USER)

As they are defined constants – if you use the quotes, it’s taking HOST and USER as a string literal.
