Question

I keep getting this whenever I run the below code:

Fatal error: Call to undefined function mysql_connect() in C:\wamp\www\php-academy\113-connect-db.php

---

    <?php
    $conn_error ='could not connect';
    $mysql_host = 'localhost';
    $mysql_user = 'root';
    $mysql_pass = '';
    mysql_connect($mysql_host, $mysql_user, $mysql_pass) or                                                   die($conn_error);

    $mysql_db = 'a_database';

    mysql_select_db($mysql_db) or die($conn_error);
    echo 'Connected!';
    ?>

Answer 1

I suspect that this is because the extension is not loaded. I would check your php_info(); to find out.

Once you do your code should work, although I prefer to assign the mysql_connect() to a variable and then call that variable in mysql_select_db() as I have below:

$defHost     = 'localhost';
$defUsername = 'username';
$defPassword = 'password';
$defDatabase = 'database_name';

$connect = mysql_connect($defHost, $defUsername, $defPassword) or die();
mysql_select_db($defDatabase, $connect) or die();
