Где находится php.ini, файл конфигурации PHP?

В этом уроке мы обсудим php.ini — основной файл конфигурации в PHP. С точки зрения начинающего, мы обсудим, для чего он предназначен, где его найти, и пару важных настроек конфигурации, которые он предоставляет.

Что такое php.ini ?

Если вы новичок в PHP или опытный разработчик, я уверен, что вы слышали о php.ini : самом важном файле конфигурации PHP.

Когда PHP запускается, он ищет файл php.ini в некоторых определенных местах и ​​загружает его. Этот файл позволяет вам настроить несколько важных параметров, о которых вы должны знать. Довольно часто вы обнаружите, что вам нужно настроить параметры в файле php.ini .

С другой стороны, вполне возможно, что вам никогда не понадобилось изменять php.ini . PHP может успешно работать с настройками, предоставленными в файле php.ini по умолчанию, поскольку PHP поставляется с этими рекомендуемыми настройками по умолчанию. На самом деле, нет критических параметров конфигурации, которые вы должны установить для запуска PHP.

Однако файл php.ini содержит несколько важных настроек, с которыми вы хотите ознакомиться. На самом деле, как разработчик PHP, это неизбежно, и вы столкнетесь с этим раньше, чем позже.

Где находится php.ini?

В этом разделе мы увидим, как найти файл php.ini, который загружается при запуске сценария PHP. Это может быть непросто — расположение файла php.ini сильно зависит от среды, в которой вы используете PHP. Если вы работаете в Windows, вы, скорее всего, найдете файл php.ini в каталоге вашей установки PHP на системном диске. С другой стороны, если вы работаете в другой операционной системе, трудно угадать точное местоположение файла php.ini — есть несколько возможностей.

Здесь на phpinfo() приходит функция phpinfo() . Он скажет вам, где находится php.ini , а также выведет всю важную информацию о конфигурации PHP.

Вы можете запустить phpinfo() , создав файл .php и вызвав эту функцию. Создайте файл phpinfo.php со следующим содержимым и поместите его в корневой каталог документа:

In this tutorial, we will explore a few methods to help you locate the correct php.ini file on your web server.

Method 1: Use phpinfo() function

The phpinfo() function displays detailed information about your PHP configuration, including the location of your php.ini file. To use this function, follow these steps:

1. Create a new PHP file on your web server. You can name it anything you like, but for this tutorial, we will name it phpinfo.php.
2. Open the phpinfo.php file in a text editor and add the following code:

You should see a page with detailed information about your PHP configuration. Look for the “Loaded Configuration File” section, which should contain the full path to your php.ini file.

Method 2: Use the command line

If you have access to the command line, you can use the `php —ini` command to find the location of the php.ini file. Follow these steps:

1. Log in to your web server using SSH or another terminal application.
2. Type the following command and press Enter:

This command will display a list of all the php.ini files that are currently being used, as well as their locations.

Method 3: Check default locations

Depending on your operating system and server configuration, the php.ini file may be located in one of the default locations. Here are some common default locations:

On Linux:

On Windows:

You can try searching for the php.ini file in these locations using your FTP or file manager.

If none of these methods work, you can contact your web hosting provider or system administrator for assistance in locating the php.ini file on your server.

Conclusion

The php.ini file is an essential configuration file for PHP. By following the methods outlined in this tutorial, you should be able to locate the correct php.ini file on your web server. Remember, the location of the php.ini file can vary depending on your server setup and operating system, so it’s important to double-check the location before making any changes to the file.

How to find the php.ini file used by the command line?

There are a few ways to locate php.ini file by command line on Linux Ubuntu, Linux Mint, and other Linux distributions. Some of the options showed here are also compatible with Windows, specially usin WSL.

What is php.ini

The php.ini file is the configuration file that is read when PHP starts up. For the server module versions of PHP, this happens only once when the web server is started. For the CGI and CLI versions, it happens on every invocation.

It is the main place where you declare changes to your PHP settings. The server is already configured with standard settings for PHP, which your site or application will use by default. Unless you need to change one or more settings, there is no need to create or modify a php.ini file.

Where is php.ini file located by default

The php.ini file is searched for in these locations (in order):

• SAPI module specific location (PHPIniDir directive in Apache 2, -c command line option in CGI and CLI)
• The PHPRC environment variable.
• The location of the php.ini file can be set for different versions of PHP. The root of the registry keys depends on 32- or 64-bitness of the installed OS and PHP. For 32-bit PHP on a 32-bit OS or a 64-bit PHP on a 64-bit OS use [(HKEY_LOCAL_MACHINE\SOFTWARE\PHP] for 32-bit version of PHP on a 64-bit OS use [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PHP]] instead. For same bitness installation the following registry keys are examined in order: [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y.z], [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y] and [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x], where x, y and z mean the PHP major, minor and release versions. For 32 bit versions of PHP on a 64 bit OS the following registry keys are examined in order: [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x.y.z], [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x.y] and [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x], where x, y and z mean the PHP major, minor and release versions. If there is a value for IniFilePath in any of these keys, the first one found will be used as the location of the php.ini (Windows only).
• [HKEY_LOCAL_MACHINE\SOFTWARE\PHP] or [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PHP], value of IniFilePath (Windows only).
• Current working directory (except CLI).
• The web server’s directory (for SAPI modules), or directory of PHP (otherwise in Windows).
• Windows directory (C:\windows or C:\winnt) (for Windows), or –with-config-file-path compile time option.

If php-SAPI.ini exists (where SAPI is the SAPI in use, so, for example, php-cli.ini or php-apache.ini ), it is used instead of php.ini . The SAPI name can be determined with php_sapi_name() (returns the type of interface between web server and PHP).

The Apache web server changes the directory to root at startup, causing PHP to attempt to read php.ini from the root filesystem if it exists.

How can I find the php.ini file from command line

php –ini

There is a simple option called —ini that you can use when run php command:

The output will show where is the php.ini used by command line, as well additional scanned configuration files:

Configuration File (php.ini) Path: /etc/php/7.4/cli Loaded Configuration File: /etc/php/7.4/cli/php.ini Scan for additional .ini files in: /etc/php/7.4/cli/conf.d Additional .ini files parsed: /etc/php/7.4/cli/conf.d/10-mysqlnd.ini, /etc/php/7.4/cli/conf.d/10-pdo.ini, /etc/php/7.4/cli/conf.d/15-xml.ini, /etc/php/7.4/cli/conf.d/20-bcmath.ini, /etc/php/7.4/cli/conf.d/20-exif.ini, /etc/php/7.4/cli/conf.d/20-gd.ini, /etc/php/7.4/cli/conf.d/20-gettext.ini, /etc/php/7.4/cli/conf.d/20-iconv.ini, /etc/php/7.4/cli/conf.d/20-intl.ini, /etc/php/7.4/cli/conf.d/20-json.ini, /etc/php/7.4/cli/conf.d/20-mbstring.ini, /etc/php/7.4/cli/conf.d/20-mysqli.ini, /etc/php/7.4/cli/conf.d/20-pdo_mysql.ini, /etc/php/7.4/cli/conf.d/20-pdo_pgsql.ini, /etc/php/7.4/cli/conf.d/20-pdo_sqlite.ini, /etc/php/7.4/cli/conf.d/20-pgsql.ini, /etc/php/7.4/cli/conf.d/20-redis.ini, /etc/php/7.4/cli/conf.d/20-simplexml.ini, /etc/php/7.4/cli/conf.d/20-sockets.ini, /etc/php/7.4/cli/conf.d/20-sqlite3.ini, /etc/php/7.4/cli/conf.d/20-xmlreader.ini, /etc/php/7.4/cli/conf.d/20-xmlwriter.ini, /etc/php/7.4/cli/conf.d/20-xsl.ini, /etc/php/7.4/cli/conf.d/20-zip.ini, /etc/php/7.4/cli/conf.d/xdebug.ini 

php-config –ini-dir

Using php-config you can list only the path where the main PHP configuration file is located:

The output is something like:

php -i and grep

The command php -i shows a complete phpinfo() result. You can find all configurations and apply grep command to filter only the .ini configuration file:

php -i | grep 'Configuration File' 

Or in Windows you can use find instead:

php -i | find/i"configuration file" 

The result to both command will be similar to:

Configuration File (php.ini) Path => /etc/php/7.4/cli Loaded Configuration File => /etc/php/7.4/cli/php.ini 

Finally you can use grep to filter all lines of the phpinfo() that shows .ini :

The output will be similar to php -i command:

Configuration File (php.ini) Path: /etc/php/7.4/cli Loaded Configuration File: /etc/php/7.4/cli/php.ini Scan for additional .ini files in: /etc/php/7.4/cli/conf.d Additional .ini files parsed: /etc/php/7.4/cli/conf.d/10-mysqlnd.ini, /etc/php/7.4/cli/conf.d/10-pdo.ini, /etc/php/7.4/cli/conf.d/15-xml.ini, /etc/php/7.4/cli/conf.d/20-bcmath.ini, /etc/php/7.4/cli/conf.d/20-exif.ini, /etc/php/7.4/cli/conf.d/20-gd.ini, /etc/php/7.4/cli/conf.d/20-gettext.ini, /etc/php/7.4/cli/conf.d/20-iconv.ini, /etc/php/7.4/cli/conf.d/20-intl.ini, /etc/php/7.4/cli/conf.d/20-json.ini, /etc/php/7.4/cli/conf.d/20-mbstring.ini, /etc/php/7.4/cli/conf.d/20-mysqli.ini, /etc/php/7.4/cli/conf.d/20-pdo_mysql.ini, /etc/php/7.4/cli/conf.d/20-pdo_pgsql.ini, /etc/php/7.4/cli/conf.d/20-pdo_sqlite.ini, /etc/php/7.4/cli/conf.d/20-pgsql.ini, /etc/php/7.4/cli/conf.d/20-redis.ini, /etc/php/7.4/cli/conf.d/20-simplexml.ini, /etc/php/7.4/cli/conf.d/20-sockets.ini, /etc/php/7.4/cli/conf.d/20-sqlite3.ini, /etc/php/7.4/cli/conf.d/20-xmlreader.ini, /etc/php/7.4/cli/conf.d/20-xmlwriter.ini, /etc/php/7.4/cli/conf.d/20-xsl.ini, /etc/php/7.4/cli/conf.d/20-zip.ini, /etc/php/7.4/cli/conf.d/xdebug.ini 

Conclusions

There are several ways to find php.ini file and other configurations files of your PHP installation using native commands on terminal.
