新的mysqli_connect cat查找数据库

Question

<?php
    $host = "localhost";
    $username = "root";
    $password = "";
    $db = "mineforums";

    $connect = mysqli_connect($host, $username, $password, $db) or die(mysqli_error($connect));
?>

That is my php code to connect to my database. Whenever I try to just connect though it doesnt do anything. The way I have my login-form setup is the action will be to this code and then doesnt do anything and when I return to my index it says database not selected because if you're logged in it says 'Welcome, {username}'

Answer 1

you could split the process

<?PHP
    $host = "localhost";
    $username = "root";
    $password = "";
    $db = "mineforums";

    $connect = mysql_connect($host, $username, $password)OR DIE("Could Not Connect To Server". MySQL_Error());

    if($connect) {
        mysql_select_db($db)OR DIE("Could Not Select Databse". MySQL_Error();
    }
?>
