In PHP 7.1 which ini file do I use? [duplicate] - php

I have found that:
When I type the following on terminal:
php -i | grep php.ini
I get the output:
The Loaded Configuration file is # /etc/php5/cli/php.ini
However, from phpinfo(), I get to see:
The loaded ini file is # /etc/php5/apache2/php.ini
Which one of these is working right now? How is it possible to have two php.ini files ?

Depends on where you are running PHP from. If you run it from command line, it uses the cli/php.ini and apache2/php.ini when run through apache.
You are executing phpinfo() through the browser, hence you get /etc/php5/apache2/php.ini as the answer. Running php -r "phpinfo();" | grep "Loaded Configuration" from the terminal should output the CLI ini. Same function, context changes.
The advantage of this system is obviously to allow different configurations depending on the context. For a simplified example, you might want to have safe_mode on in apache but it's unnecessary in CLI mode.
Your .ini paths are actually quite unusual. Normally, the default .ini is just php.ini and CLI .ini is called php-cli.ini and they reside in the same folder.
I'm no expert on the subject but this should be the basic idea. If anyone has any corrections, I'd be happy to hear them.

Symfony 5 : could not find driver [duplicate]

A few years ago I installed Apache 2.2x and PHP 5.3.1 on a Linux server I maintain. I used .tar.gz's and built them as instructed (instead of rpms and what-have-you). And all was fine.
Today I need to install this which seems like a PHP library. I went through all the steps up to make install, and I found ibm_db2.so in $PHP_HOME/lib/extensions/somecomplicatedname/ibm_db2.so.
The great catch is the last step is to configure file php.ini, but there aren't any php.ini files on my system. Horror of horrors. PHP works fine, except of course for this newfangled ibm_db2 thingamajig that I want to use so somebody can use a GUI to tinker with DB2. (I tried a small PHP script which fails and indicates that the ibm_db2 functions are not available.)
I have to deal with PHP once every few years, so please enlighten me at a very basic level about what I could do to enable web-based GUI access to DB2.
On the command line execute:
php --ini
You will get something like:
Configuration File (php.ini) Path: /etc/php5/cli
Loaded Configuration File: /etc/php5/cli/php.ini
Scan for additional .ini files in: /etc/php5/cli/conf.d
Additional .ini files parsed: /etc/php5/cli/conf.d/curl.ini,
/etc/php5/cli/conf.d/pdo.ini,
/etc/php5/cli/conf.d/pdo_sqlite.ini,
/etc/php5/cli/conf.d/sqlite.ini,
/etc/php5/cli/conf.d/sqlite3.ini,
/etc/php5/cli/conf.d/xdebug.ini,
/etc/php5/cli/conf.d/xsl.ini
That's from my local dev-machine. However, the second line is the interesting one. If there is nothing mentioned, have a look at the first one. That is the path, where PHP looks for the php.ini file.
You can grep the same information using phpinfo() in a script and call it with a browser. It’s mentioned in the first block of the output. php -i does the same for the command line, but it’s quite uncomfortable.
The best way to find this is:
Create a PHP (.php) file and add the following code:
<?php phpinfo(); ?>
and open it in a browser. It will show the file which is actually being read!
Updates by the OP:
The previously accepted answer is likely to be faster and more convenient for you, but it is not always correct. See comments on that answer.
Please also note the more convenient alternative <?php echo php_ini_loaded_file(); ?> mentioned in this answer.
This works for me:
php -i | grep 'php.ini'
You should see something like:
Loaded Configuration File => /usr/local/lib/php.ini
P.S.
To get only the php.ini path, use:
php -i | grep /.+/php.ini -oE
In a command window, type
php --ini
It will show you the path something like:
Configuration File (php.ini) Path: /usr/local/lib
Loaded Configuration File: /usr/local/lib/php.ini
If the above command does not work then use this:
echo phpinfo();
Use the following command to find the php.ini file path on Linux.
locate php.ini
Output:
/etc/php.ini
/etc/php.ini.rpmnew
/usr/share/doc/php-common-5.4.45/php.ini-development
/usr/share/doc/php-common-5.4.45/php.ini-production
Or try this other way:
php --ini
It shows the path result.
This command should help you to find it
php -r "phpinfo();" | grep php.ini
PHP comes with two native functions to show which configuration file is loaded:
php_ini_loaded_file returns the loaded .ini file
php_ini_scanned_files returns a list of .ini files parsed from the additional ini directory
Depending on your setup, Apache and CLI might use different .ini files. Here are the two solutions:
Apache:
Just add the following in a PHP (.php) file and open it in your browser:
print php_ini_loaded_file();
print_r(php_ini_scanned_files());
CLI:
Copy-paste in your terminal:
php -r 'print php_ini_loaded_file(); print_r(php_ini_scanned_files());'
phpinfo();
will tell you its location, or from the command line
php -i
Try one of these solutions
In your terminal, type find / -name "php.ini"
In your terminal, type php -i | grep php.ini. It should show the file path as "Configuration File (php.ini) Path => /etc"
If you can access one of your PHP files, open it in a editor (Notepad) and insert phpinfo(); after <?php on a new line. This will tell you the php.ini location.
You can also talk to PHP in interactive mode. Just type php -a in the terminal and type phpinfo(); after the PHP interpreter initiated.
Run this in the command line:
php -r "echo php_ini_loaded_file().PHP_EOL;"
find / -name php.ini
Hey... it worked for me!
You can get more information about your configuration files using something like:
$ -> php -i | ack config # Use fgrep -i if you don't have ack
Configure Command => './configure' ...
Loaded Configuration File => /path/to/php.ini
For SAPI: php-fpm
There isn't any need to create a php.info file (it is not a good policy to leave it for the world to read anyway). On the command line:
php-fpm -i | more
Somewhere in its output, it will show this line:
Configuration File (php.ini) Path => /etc

Eclipse and Xdebug does not parse additional ini files in /etc/php5/conf.d

I have setup Eclipse 3.6.2 on Ubuntu 11.4 for AMD64 and Xdebug.
Eclipse was installed with zip download from eclipse.org.
PHP and Xdebug were setup with apt-get.
When I run the PHP script in the shell they will use the /etc/php5/php.ini file and parse additional ini files in /etc/php5/conf.d/.
When I run in Eclipse (run mode or debug mode) it will only parse php.ini and no additional ini files.
Basically, all extensions, are not loaded.
It is an intentional bug.
PDT executes php with "-n" option always. It makes additional ini files unavailable.
see https://bugs.eclipse.org/bugs/show_bug.cgi?id=339547
also https://bugs.eclipse.org/bugs/show_bug.cgi?id=347618
BTW, you'll be able to add a shell script which trims "-n" option as PHP Executable.(Preferences>PHP>PHP Executables)
For example,
#!/bin/sh
if [ $1 = "-n" ]; then
shift;
fi
/usr/bin/php $*
The answer #atlanto gives as a work around did and does still work, but recent version of Eclipse (I'm on Neon) has a fix that may work for you if you don't mind using the php.ini and conf.d set by default for the php executable.
The failing to load additional files only happens now if you put in an explicit php.ini file when defining a PHP executable. Leave this blank and check the box Use system default php.ini configurate.
Now if you use the location/php.ini that was specified as default when the executable was built, it will respect scanning of conf.d directories.
Here's how to check if your php has scanning conf.d enable and where the approriate default location is:
php -i "(command-line 'phpinfo()')" | grep "Configure Command"
You should see something like:
Configure Command => './configure' '--prefix=/usr/local/Cellar/php5/5.6.29_5'
'--localstatedir=/usr/local/var' '--sysconfdir=/usr/local/etc/php/5.6'
'--with-config-file-path=/usr/local/etc/php/5.6'
'--with-config-file-scan-dir=/usr/local/etc/php/5.6/conf.d'
'--mandir=/usr/local/Cellar/php56/5.6.29_5/share/man'
... and so on...
The items that matter are:
with-config-file-path: this where it will look for your php.ini file
with-config-file-scan-dir: this is the conf.d that will be scanned
If you still wish to choose a different in location than the default for the executable your options are:
Inline the module directives from and file in conf.d into your alternate php.ini
Rebuild php and set the above options to your new location as default
Use the wrapper script #atlanto indicates

2 php.ini files

I have found that:
When I type the following on terminal:
php -i | grep php.ini
I get the output:
The Loaded Configuration file is # /etc/php5/cli/php.ini
However, from phpinfo(), I get to see:
The loaded ini file is # /etc/php5/apache2/php.ini
Which one of these is working right now? How is it possible to have two php.ini files ?
Depends on where you are running PHP from. If you run it from command line, it uses the cli/php.ini and apache2/php.ini when run through apache.
You are executing phpinfo() through the browser, hence you get /etc/php5/apache2/php.ini as the answer. Running php -r "phpinfo();" | grep "Loaded Configuration" from the terminal should output the CLI ini. Same function, context changes.
The advantage of this system is obviously to allow different configurations depending on the context. For a simplified example, you might want to have safe_mode on in apache but it's unnecessary in CLI mode.
Your .ini paths are actually quite unusual. Normally, the default .ini is just php.ini and CLI .ini is called php-cli.ini and they reside in the same folder.
