mysql连接错误，期望参数1为mysqli

Question

（！）警告：mysqli_select_db（）期望参数1为mysqli，第7行的C：\ wamp \ www \ go4shop \ config.php中给出的字符串

我对下面的代码感到愤怒。请有人帮帮我

<?php 
$dbhost = "localhost"; 
$dbuser = "root"; 
$dbpassword = "1234"; 
$dbdatabase = "go4shop"; $c``onfig_basedir = "http://localhost/go4shop/"; 
$config_sitename = "Go4Shop"; 
$db = mysqli_connect($dbhost, $dbuser, $dbpassword); mysqli_select_db($dbdatabase, $db); 
?>

Answer 1

首先是Linkname，然后是数据库名称......

mysqli_select_db ( mysqli $link , string $dbname )

或在你的情况下

 mysqli_select_db($db, $dbdatabase)
