Please note that this property returns different versionstrings for MariaDB instances on LINUX and WINDOWS environments.
For a MariaDB instance 10.0.17:
on LINUX, this returns strings like "10.0.17-MariaDB-log"
on WINDOWS environments, this returns strings like "5.5.5-10.0.17-MariaDB-log"
To avoid this extra "5.5.5" on windows environments, you could use the SQL query "select version();" rather than this property of the mysqli extension
mysqli::$server_info
mysqli::get_server_info
mysqli_get_server_info
(PHP 5, PHP 7, PHP 8)
mysqli::$server_info -- mysqli::get_server_info -- mysqli_get_server_info — 返回 MySQL 服务器的版本号
说明
面向对象风格
过程化风格
返回字符串，表示 MySQLi 扩展连接的 MySQL 服务器的版本号。
返回值
表示服务器版本的字符串。
示例
示例 #1 $mysqli->server_info 示例
面向对象风格
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password");
/* print server version */
printf("Server version: %s\n", $mysqli->server_info);过程化风格
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password");
/* print server version */
printf("Server version: %s\n", mysqli_get_server_info($link));以上示例的输出类似于：
Server version: 8.0.21
