PHP - 如果域

Question

我有以下的片上多域1個模板設置編碼的：當我

<?php $host = parse_url($domain, PHP_URL_HOST); 
if($host == 'www.justdoors.co') { 
echo "action goes here"; 
} ?> 

出於某種原因，它不進行動作的www.justdoors.co域名，我錯過了什麼？

Answer 1

使用$_SERVER['SERVER_NAME']或$_SERVER['HTTP_HOST']可變

$host = $_SERVER['HTTP_HOST']; 
if($host == "www.justdoors.co" or $host == "justdoors.co") { 
    //do anything you want to do 
} 

Answer 2

我以前在我的服務器上成功地使用了它。

<?php if ($_SERVER['SERVER_NAME'] == 'www.domain.com') { echo ''; } ?> 

Answer 3

我曾經嘗試這樣做，它的工作完美..

<?php 
function conn() 
{ 
    $ora_con=0; 
    //development connection building 
    if ($_SERVER['SERVER_NAME'] == 'xyz.com') 
    {$username='scott'; 
    $password = 'tiger'; 
    $ora_conn_string = 'conn_name:port_no/db_name'; 
    //echo "<br>development connection building"; 
     $ora_con = oci_connect($username,$password,$ora_conn_string); 
    //echo '<br>dev connection build<br>'; 
    } 
    //Production connection building 
    elseif ($_SERVER['SERVER_NAME'] == 'abc.net') 
     {$username='prod_scott'; 
     $password = 'prod_tiger'; 
     $ora_conn_string = 'conn_name:port_no/db_name'; 
     //echo "<br>Production connection building"; 
     $ora_con = oci_connect($username,$password,$ora_conn_string); 
     //echo '<br>Prod connection build<br>'; 
     } 

    return $ora_con; 
} 
?>
