Codeigniter Environment setting
提问by Zohaib
Codeigniter development environment is not setting. I always use this code in index.php. but i don't understand why i am getting "production" as output while i am working on localhost.
Codeigniter 开发环境未设置。我总是在 index.php 中使用这段代码。但我不明白为什么我在本地主机上工作时将“生产”作为输出。
switch(dirname(__FILE__)){
case "H:\wamp\www\sitedirectory":
define('ENVIRONMENT', 'development');
break;
default:
define('ENVIRONMENT', 'production');
break;
}
echo ENVIRONMENT ; // output is "production" while i am on localhost
echo dirname(__FILE__) ; // output is "H:\wamp\www\sitedirectory"

That's strange. It did the exact same thing for me. Could you try something like this?
真奇怪。它对我做了完全相同的事情。你能试试这样的吗？
switch($_SERVER["HTTP_HOST"]){
case "localhost":
define('ENVIRONMENT', 'development');
break;
default:
define('ENVIRONMENT', 'production');
break;
}
echo ENVIRONMENT ; // output development

To dynamically set the ENVIRONMENT based on the server's IP, below I have used regular expression to check for local IP's such as 127.0.* and 10.0.*.
为了根据服务器的 IP 动态设置环境，下面我使用正则表达式来检查本地 IP，例如 127.0.* 和 10.0.*。
At the root of you project look to index.phpand replace:
在您项目的根目录查找index.php并替换：
define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');
with:
和：
$server_ip = getHostByName(getHostName());
if (preg_match("/^(127\.0\.|10\.0\.).+/i", $server_ip)) {
define("ENVIRONMENT", "development");
define("BASEURL", "http://localhost:8000/");
} else {
define("ENVIRONMENT", "production");
define("BASEURL", "https://domain.com/");
}
Make sure to replace the value from BASEURLwith your own and in application/config/config.phpadd:
确保BASEURL用您自己的值替换并application/config/config.php添加：
$config['base_url'] = BASEURL;
To improve further add to application/config/database.phpright before the database settings $db['default'] = array(:
为了进一步改进application/config/database.php在数据库设置之前添加$db['default'] = array(：
if(ENVIRONMENT !== 'production') {
$db = [
'username' => '',
'password' => '',
'database' => '',
'hostname' => '127.0.0.1'
];
} else {
$db = [
'username' => '',
'password' => '',
'database' => '',
'hostname' => ''
];
}

Adding on to the other answers. Now the below answer might look like an overkill (if you have to define the environment variables then why use the HTTP_HOST at all? Well in my experience CI fails to reflect any changes made to the environment variables even after restarting apache. It somehow gets the updated values when sending a request from the CLI.)
补充其他答案。现在下面的答案可能看起来有点矫枉过正（如果你必须定义环境变量，那么为什么要使用 HTTP_HOST？根据我的经验，即使在重新启动 apache 之后，CI 也无法反映对环境变量所做的任何更改。它以某种方式获得了从 CLI 发送请求时更新的值。）
if (php_sapi_name() === 'cli')
{
// incase the request is made using the cli, the $_SERVER['HTTP_HOST'] will not be set
define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');
}
else
{
switch ($_SERVER["HTTP_HOST"])
{
case "localhost":
define('ENVIRONMENT', 'development');
break;
default:
define('ENVIRONMENT', 'production');
break;
}
}

You can Also use this one to auto change Environment in codeigniter
您也可以使用这个来自动更改 codeigniter 中的环境
if ($_SERVER['HTTP_HOST'] == 'localhost'){
define('ENVIRONMENT', 'development');
}else{
define('ENVIRONMENT', 'production');
}
