How to find the php.ini file used by the command l

Question

I need to enable pdo_mysql in my EasyPhp environment, so I went to php.ini file and uncommented the following line:

extension=php_pdo_mysql.dll

Unfortunately I still have the same problem. I'm using the CLI so I suppose I need to locate the php.ini file used by the CLI. How can I find it?

Answer 1

There is no php.ini used by the command line. You have to copy the file from ...EasyPHP-<<version>>\apache\php.ini to ...EasyPHP-<<version>>\php\php.ini than edit the one in php directory

Run php --ini in your terminal, you'll get all details about ini files

[root@tamilan src]# php --ini

If you want all the configuration files loaded, this is will tell you:

php -i | grep "\.ini"

Some systems load things from more than one ini file. On my ubuntu system, it looks like this:

$  php -i | grep "\.ini"
Configuration File (php.ini) Path => /etc/php5/cli
Loaded Configuration File => /etc/php5/cli/php.ini
Scan this dir for additional .ini files => /etc/php5/cli/conf.d
additional .ini files parsed => /etc/php5/cli/conf.d/apc.ini,
/etc/php5/cli/conf.d/curl.ini,
/etc/php5/cli/conf.d/gd.ini,
/etc/php5/cli/conf.d/mcrypt.ini,
/etc/php5/cli/conf.d/memcache.ini,
/etc/php5/cli/conf.d/mysql.ini,
/etc/php5/cli/conf.d/mysqli.ini,
/etc/php5/cli/conf.d/pdo.ini,
/etc/php5/cli/conf.d/pdo_mysql.ini

Answer 4

On OSX Mavericks, running:

$ php -i | grep 'Configuration File'

Returned:

Configuration File (php.ini) Path => /etc
Loaded Configuration File:         (none)

In the /etc/ directory was:

php.ini.default

(as well as php-fpm.conf.default)

I was able to copy php.ini.default to php.ini, add date.timezone = "US/Central" to the top (right below [php]), and the problem is solved.

(At least the error message is gone.)

Answer 5

Somtimes things aren't always as they seem when in comes to config files in general. So here I'm applying my usual methods for exploring what files are opened by a process.

I use a very powerful and useful command-line program called strace to show me what's really going on behind my back!

$ strace -o strace.log php --version
$ grep php.ini strace.log

Strace digs out kernel (system) calls that your program makes and dumps the output into the file specified by -o

It's easy to use grep to search for occurrences of php.ini in this log. It's pretty obvious looking at the following typical response to see what is going on.

open("/usr/bin/php.ini", O_RDONLY)      = -1 ENOENT (No such file or directory)
open("/etc/php.ini", O_RDONLY)          = 3
lstat("/etc/php.ini", {st_mode=S_IFREG|0644, st_size=69105, ...}) = 0

Answer 6

From what I remember when I used to use EasyPHP, the php.ini file is either in C:\Windows\ or C:\Windows\System32
