PHP-MySQL连接错误

Question

我正在尝试通过以下代码通过PHP连接到MySQL。

<?php

$dbhost = 'localhost';
$dbuser = 'root';
$pass   = 'pass';


 $con = mysql_connect($dbhost,$dbuser,$pass);
 if (!$con)
   {
   die('Could not connect: ' . mysql_error());
   }

 mysql_select_db("test", $con);

 mysql_query("UPDATE cbdb SET fax = '36160'
 WHERE cemail = 'test_cemail@gmail.com' AND cbref = 'test_cbref'");

 mysql_close($con);
 ?>

但是，即使显示MySQL连接错误，也会显示错误。

Answer 1

您缺少；在传递后使用以下语法

   $db_host=" "; //the host name of the sql server (if you do not know, leave as localhost. usually works)
   $db_name=" ";  //the name of the database
   $db_user=" ";  //the username that is associated with the database
   $db_pass=" "; //the password for the username

   $dbc=mysql_connect($db_host,$db_user,$db_pass) OR DIE (mysql_error());
   $dbs=mysql_select_db($db_name) OR DIE (mysql_error());

Answer 2

“pass”后有没有漏掉分号？

Answer 3

您在$pass行中缺少分号。
