如何连接多个远程sql server？

Question

我的本​​地 sql 太大了。

现在我想添加另一个远程mysql。

任何人都可以在以下本地mysql连接中设置远程mysql吗？

<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"

#Localhost mysql: Make it only read

$hostname_saha = "localhost";
$database_saha = "bdwebstk_1a";
$username_saha = "bdwebstk_1a";
$password_saha = "111111111111"; 

#remote mysql : Plesae make it read and write

$hostname_saha = "xx.yy.zz.zz";
$database_saha = "horjecom_aw";
$username_saha = "horjecom_aw";
$password_saha = "000000000000000000"; 

$saha = mysqli_connect($hostname_saha, $username_saha, $password_saha, $database_saha) or trigger_error(mysqli_error($saha),E_USER_ERROR); 

mysqli_set_charset( $saha, 'utf8');

?>

您必须为每个 SQL Server 创建单独的连接 - 最好在单独的字段中。

我强烈建议从他们将服务的业务中命名您的连接名称。 另一个强烈建议您将配置文件存储在代码库之外https://stackoverflow.com/a/3724607/3711660

文件 localhost_sql.php

<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"

#Localhost mysql: Make it only read

$hostname_saha = "localhost";
$database_saha = "bdwebstk_1a";
$username_saha = "bdwebstk_1a";
$password_saha = "111111111111"; 

$sqlcon_localhost= mysqli_connect($hostname_saha, $username_saha, $password_saha, $database_saha) or trigger_error(mysqli_error($saha),E_USER_ERROR); 

mysqli_set_charset( $sqlcon_localhost, 'utf8');
?>

文件remote_sql.php

<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"

#Localhost mysql: Make it only read


$hostname_saha = "66.96.566.53";
$database_saha = "horjecom_aw";
$username_saha = "horjecom_aw";
$password_saha = "000000000000000000"; 


$sqlcon_remote= mysqli_connect($hostname_saha, $username_saha, $password_saha, $database_saha) or trigger_error(mysqli_error($saha),E_USER_ERROR); 

mysqli_set_charset( $sqlcon_remote, 'utf8');
?>

然后在下面的另一个文件中使用它

require('remote_sql.php');
$result = mysqli_query($sqlcon_remote, "SELECT DATABASE()")
