问题描述

好的，这是我现在的问题.我正在使用PHP 5.5.12和MySQL 5.6.17.在我的PHP设置中检查了php mysqli_connect，但仍然出现错误.有帮助吗?预先感谢.

Okay so this is my problem now. I am using PHP 5.5.12 and MySQL 5.6.17. The php mysqli_connect is checked on my php settings but still getting error. ANy help? Thanks in advance.

这是我的dbcon.php

Here is my dbcon.php

<?php
//Connect to the database 
$link = new mysqli_connect ("localhost", "root", "", "towertec_master"); 
if (mysqli_connect_errno()) 
{
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}?>

这是我的main.php

And this is my main.php

<?php
include ("lib\dbcon.php");

// is a client logged in?
include("lib/login_check.php");

include("lib/fetch_org_data.php");
$thispage="main";   
?>

这是错误消息:

Fatal error: Class 'mysqli_connect' not found in C:\wamp\www\Trading\lib\dbcon.php on line 3
Call Stack
#   Time    Memory  Function    Location
1   0.0014  244472  {main}( )   ..\main.php:0
2   0.0023  247912  include( 'C:\wamp\www\Trading\lib\dbcon.php' )  ..\main.php:2

推荐答案

mysqli_connect 是一个函数，而不是一类.您想要的是:

mysqli_connect is a function, not a class. What you want is either:

$link = mysqli_connect(...);

或

$link = new mysqli(...);

两者都是等效的.
