HomeBackend DevelopmentPHP TutorialWIN 7 64位下PHP无法链接MYSQL

WIN 7 64位下IIS+php(5.2.5)+mysql(5.5.27)
安装过程没有报错。
独运PHP文件正常。

一边链接数据库就不行了。
安装ECSHOP,检查过程,提示MySQL....不支持
运行PHPMYADMIN 提示MYSQL加载,

PHP.ini文件如下
;extension=php_bz2.dll

回复讨论(解决方案)

代码是什么? 报错了没有?

PHPMYADMIN下提示:

缺少 mysqli 扩展。请检查 PHP 配置。 WIN 7 64位下PHP无法链接MYSQL

链接数据库提示:

Fatal error: Call to undefined function mysql_connect() in

链接数据库代码:

$server_name="localhost";
$server_user="root";
$server_pass="密码";
$server_database="数据库名"; 

$conn=mysql_connect($server_name,$server_user,$server_pass);
mysql_select_db($server_database,$conn);
mysql_query("set names gb2312");

phpinfo 看看mysql 扩展是否开启, php/ext 目录中没有 php_mysql.dll 文件吗?

phpinfo 无MYSQ信息。

php/ext 目录下有 php_mysql.dll 文件,并已经复制WINDOWS/SYSTEM32

extension=php_mysql.dll
extension=php_pdo_mysql.dll
 已经开启

原因应该就是MYSQL扩展没被加载起。

PHP.ini文件扩展都开了。
GD都能加载。
就MYSQL加载不上。

应该是没有dll文件

WINDOWS/SYSTEM32/(PHP/ext) 下都有php_mysql.dll 、 php_pdo_mysql.dll

不是把 php_mysql.dll 文件,并已经复制WINDOWS/SYSTEM32,而是libmysql.dll

libmysql.dll  也复制了的

已经解决了

你怎么解决的呀 正好遇到这样的问题

不是因为php.ini的问题, 是libmysql 没被加载

如何解决的?我也碰到这个问题

extension_dir 中指定绝对路径

解决办法:
右键我的电脑--属性--高级--环境变量
找到path最后面加上 D:\PHP,这个目录是你的PHP根目录哦,然后重启apache,打印 phpinfo(),哈哈!终于看到了久违了的mysql被加载进来,(改了path之后,最好是重启一下电脑哦。。。。)

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
