致命错误:在将 PHP 5.4.22 和 MySQL 5.5 与 Apache 2.4.7 连接时调用未定义的函数 my

问题描述

我正在尝试使用 Apache 2.4.7 作为 Web 服务器连接 PHP 5.4.22 和 MySQL 5.5.所有这三个单独工作正常.但是，当我尝试将 PHP 与 MySQL 连接时，出现错误:

I am trying to connect PHP 5.4.22 and MySQL 5.5 with Apache 2.4.7 as the web server. All three of these individually are working fine. However, when I try to connect PHP with MySQL I get the error:

致命错误:调用未定义的函数 mysqli_connect() in..."

"Fatal error: Call to undefined function mysqli_connect() in..."

db_connect.php 代码

$con = mysqli_connect("localhost","root","root","mylab_dev");

if (mysqli_connect_errno($con))
{
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$conn->close();

httpd.conf 配置:

ServerRoot "c:/Apache24"

#Listen 12.34.56.78:80
Listen 80

LoadModule php5_module "C:/php/php5apache2_4.dll" (Verified the existence of the physical file)

AddHandler application/x-httpd-php .php

DirectoryIndex index.php index.html
PHPIniDir c:/php

修改php.ini-development文件为php.ini

Modified php.ini-development file to php.ini

; extension_dir = "./"

; On windows:

extension_dir = "ext"

extension=php_mysql.dll  --> Uncommented

extension=php_mysqli.dll --> Uncommented

相应地设置日期时区

我注意到一件事，但不确定这是否是原因，在 phpinfo() 页面中，我看到了 MySQL 信息，但没有看到任何显示 mysqli() 的内容.我应该吗?

extension_dir = "C:Program Filesphpext"

extension=php_mysql.dll
extension=php_mysqli.dll
