PHP MySQL连接错误

我试图通过以下代码通过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);
 ?>

---

您是否在“pass”之后缺少分号？
您在
$pass
行中缺少分号。
您缺少；在pass之后使用以下语法

   $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());

只是一个提示，您可能需要设置错误报告（E_ALL）；在php脚本的开头。这样，您将收到所有错误的通知。现在看起来你正在抑制一些错误。我从中找到了这篇文章。
