Question

我有一个本地和远程服务器，我正在开发一个项目

//local
$servername = "localhost";
$username = "bob";
$password = "fred";
$dbname = "jane";

//remote
$servername = "arthur";
$username = "Milly";
$password = "Horace";
$dbname = "Erastus";

目前我正在评论//本地或//远程位，具体取决于我连接的方式。当然，我经常错误地覆盖连接文件，这很痛苦。

是否有某种方法可以检测到我所在的服务器，然后自动连接。我试过谷歌搜索，但无法改变任何可能因为我想不出正确的搜索条件。

Answer 1

执行此操作的方法不止一种，但您可以尝试的方法是从IP地址检测您所在的服务器

if ($_SERVER['SERVER_ADDR'] === '127.0.0.1') {
  $servername = "localhost";
  $username = "bob";
  $password = "fred";
  $dbname = "jane";
} else {
   //remote
  $servername = "arthur";
  $username = "Milly";
  $password = "Horace";
  $dbname = "Erastus";
}

Answer 2

您可以尝试以下代码： -

<?php

if ($_SERVER['SERVER_NAME'] == "localhost") {
$servername = "localhost";
$username = "bob";
$password = "fred";
$dbname = "jane";
}
elseif ($_SERVER['SERVER_NAME'] == "google.com") {
$servername = "arthur";
$username = "Milly";
$password = "Horace";
$dbname = "Erastus";
}
else {
echo "No configuration found!";
exit;
}

Answer 3

试试这段代码： -

$conn = new mysqli($servername1, $username1, $password1);
if (! $conn->connect_error) {
$conn = new mysqli($servername2, $username2, $password2);    
}

或检查： -

$_SERVER['HTTP_HOST']=="localhost"

不同服务器上的php / mysql连接
