找不到类'mysqli_connect'

Question

好的,这就是我现在的问题.我使用的是PHP 5.5.12和MySQL 5.6.17.php mysqli_connect在我的php设置上检查但仍然出错.有帮助吗？提前致谢.

这是我的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

<?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

#   Time    Memory  Function    Location

mysqli_connect是一个功能,而不是一个类.你想要的是:

$link = mysqli_connect(...);

要么

$link = new mysqli(...);

两者都是等价的.
