How can I know which 'php.ini' file is used?
PhpPhp IniPhp Problem Overview
I search the path where the php.ini file is located in our Linux Ubuntu server, and I found many php.ini files when executing the command find / -name php.ini
. So how can I know exactly from a PHP script web page where the php.ini is located?
Php Solutions
Solution 1 - Php
php --ini
For the webserver-SAPIs use phpinfo()
Here's some sample output:
bash-3.2# php --ini
Configuration File (php.ini) Path: /usr/local/php5/lib
Loaded Configuration File: /usr/local/php5/lib/php.ini
Scan for additional .ini files in: /usr/local/php5/php.d
Additional .ini files parsed: /usr/local/php5/php.d/10-extension_dir.ini,
/usr/local/php5/php.d/20-extension-opcache.ini,
/usr/local/php5/php.d/40-openssl.ini,
/usr/local/php5/php.d/50-extension-apcu.ini,
/usr/local/php5/php.d/50-extension-curl.ini,
/usr/local/php5/php.d/50-extension-gmp.ini,
/usr/local/php5/php.d/50-extension-imap.ini,
/usr/local/php5/php.d/50-extension-intl.ini,
/usr/local/php5/php.d/50-extension-mcrypt.ini,
/usr/local/php5/php.d/50-extension-mssql.ini,
/usr/local/php5/php.d/50-extension-pdo_pgsql.ini,
/usr/local/php5/php.d/50-extension-pgsql.ini,
/usr/local/php5/php.d/50-extension-propro.ini,
/usr/local/php5/php.d/50-extension-raphf.ini,
/usr/local/php5/php.d/50-extension-readline.ini,
/usr/local/php5/php.d/50-extension-xdebug.ini,
/usr/local/php5/php.d/50-extension-xsl.ini,
/usr/local/php5/php.d/60-extension-pecl_http.ini,
/usr/local/php5/php.d/99-liip-developer.ini
Solution 2 - Php
You can use php_ini_loaded_file().
Taken from 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().
Also, you should note that if you run a PHP script from CLI, it's possible that a different php.ini
file will be used than if a server (e.g., nginx or Apache) runs it.
Other options:
-
php -i|grep 'php.ini'
-
create
info.php
that contains<?php phpinfo();
in the webroot, and run it in your browser
Solution 3 - Php
Note that the configuration loaded for PHP when it's being used in the console is different from the configuration for the web process. Most PHP installations would come with a php.ini file for Apache and another for CLI.
To know which configuration file is used for the console commands, use
php -i | grep "Configuration File"
To know which configuration file is used for the web processes, follow these steps
- Create an info file (preferably in the root folder)
- The contents of this file should be
<?php phpinfo(); ?>
- Ctrl + F and search for "Configuration File"
Solution 4 - Php
You have to use the PHP method php_ini_loaded_file
(only after PHP 5.2.4)
> php_ini_loaded_file — Retrieve a path to the loaded php.ini file
PHP website example:
<?php
$inipath = php_ini_loaded_file();
if ($inipath) {
echo 'Loaded php.ini: ' . $inipath;
} else {
echo 'A php.ini file is not loaded';
}
?>

Solution 5 - Php
Just add a file like this:
<?php
phpinfo();
?>
Then look for
Loaded Configuration File
You'll see the full path for the php.ini file.
Solution 6 - Php
Create a simple page and it will be listed there!
<?php
phpinfo();
?>
Solution 7 - Php
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 three different versions of PHP on my server and I got the fix instantly then.
