How to know which php.ini is used?
提问by pheromix
I search the path where the php.ini file is located in our Linux Ubuntu server, and I found many php.ini when executing the command find / -name php.ini. So how to know exactly from a php script web page where the php.ini is located ?

php --ini
For the webserver-SAPIs use phpinfo()

You can use php_ini_loaded_file()
Taken from php.net:
摘自 php.net：
$inipath = php_ini_loaded_file();
if ($inipath) {
echo 'Loaded php.ini: ' . $inipath;
} else {
echo 'A php.ini file is not loaded';
}
You may also want to check php_ini_scanned_files()
您可能还想检查php_ini_scanned_files()
Also, you should note that if you run a PHP script from CLI, it's possible that a different php.inifile will be used than if a server (ie nginx or apache) runs it.
另外，您应该注意，如果您从 CLI 运行 PHP 脚本，则可能php.ini会使用与服务器（即 nginx 或 apache）运行它不同的文件。
Other options:
其他选项：
php -i|grep 'php.ini'- create
info.phpthat contains<?php phpinfo();in the webroot, and run it in your browser
php -i|grep 'php.ini'- 创建
info.php包含<?php phpinfo();在 webroot 中的文件，并在浏览器中运行它

Note that the configuration loaded for PHP when it's being used on the console is different from the configuration for the web process. Most PHP installations would come with a php.ini for apache and another for CLI.
请注意，在控制台上使用 PHP 时为 PHP 加载的配置与 Web 进程的配置不同。大多数 PHP 安装都会附带一个用于 apache 的 php.ini 和另一个用于 CLI。
To know which configuration file is used for the console commands, use
要知道哪个配置文件用于控制台命令，请使用
$ php -i | grep "Configuration File"
To know which configuration file is used for the web processes, follow these steps
要了解 Web 进程使用哪个配置文件，请按照下列步骤操作
- Create an info file [preferably in the root folder]
- The contents of this file should be
<?php phpinfo(); ?> Ctrl+Fand search for "Configuration File"
- 创建一个信息文件[最好在根文件夹中]
- 这个文件的内容应该是
<?php phpinfo(); ?> Ctrl+F并搜索“配置文件”

You have to use the php method php_ini_loaded_file(only after php 5.2.4)
你必须使用php方法php_ini_loaded_file（只有在php 5.2.4之后）
php_ini_loaded_file — Retrieve a path to the loaded php.ini file
php_ini_loaded_file — 检索加载的 php.ini 文件的路径
php website example:
php网站示例：
<?php
$inipath = php_ini_loaded_file();

}
?>

As mentioned, "find / -name php.ini" will help get all the php.ini files. The one you may be editing may not be the one from which the server is drawing the command from! I found php.ini for 3 different versions of php on my server and I got the fix instantly then.
如前所述，“find / -name php.ini”将有助于获取所有 php.ini 文件。您可能正在编辑的那个可能不是服务器从中提取命令的那个！我在我的服务器上找到了 3 个不同版本的 php 的 php.ini，然后我立即得到了修复。
