PEAR on Windows: How to change pear.ini location

Question

I am trying to install a PEAR package into my recent XAMPP PHP installation (PHP 5.3.1) on Windows 7 64-bit.

Installing new packages fails because PEAR tries to access c:\windows\pear.ini instead of the existing c:\path_to_xampp\php\pear.ini. This results (rightly) in a permission denied error. I am logged on as Administrator, but the Windows directory enjoys some additional protection IIRC.

Rather than fiddle with write rights in the windows directory, I would like to use the existing pear.ini file.

Does anybody know where to change PEAR's behaviour accordingly?

Solution 1

Not entirely sure but PEAR registered the following keys in the registry of my machine

REGEDIT4
[HKEY_CURRENT_USER\Environment]
"PHP_PEAR_SYSCONF_DIR"="D:\\webserver\\xampp\\php"
....

And PEAR/Config.php contains the following code snippet:

if (getenv('PHP_PEAR_SYSCONF_DIR')) {
    define('PEAR_CONFIG_SYSCONFDIR', getenv('PHP_PEAR_SYSCONF_DIR'));

and the constructor for the Config class

function PEAR_Config($user_file = '', $system_file = '', $ftp_file = false,
                         $strict = true)
    {
        $this->PEAR();
        PEAR_Installer_Role::initializeConfig($this);
        $sl = DIRECTORY_SEPARATOR;
        if (empty($user_file)) {
            if (OS_WINDOWS) {
                $user_file = PEAR_CONFIG_SYSCONFDIR . $sl . 'pear.ini';
            } else {
                $user_file = getenv('HOME') . $sl . '.pearrc';
            }
        }

$user_file = PEAR_CONFIG_SYSCONFDIR . $sl . 'pear.ini'; seems to be the line that makes "my" PEAR installation use the file D:\webserver\xampp\php\pear.ini.
If that's correct all you have to do is to somehow set the environment variable PEAR_CONFIG_SYSCONFDIR

Solution 2

Another way is edit your windows system environment and add PHP_PEAR_SYSCONF_DIR variable pointing to php's dir.

Solution 3

To change the path from c:\windows\pear.ini to c:\path_to_xampp\php\pear.ini you can download this file at http://pear.php.net/go-pear.phar and place it in your c:\path_to_xampp\php folder. Run:

php go-pear.phar

Change the location of your pear.ini (11) to c:\path_to_xampp\php ($prefix\pear.ini). Save and run the new file c:\path_to_xampp\php\PEAR_ENV.reg. Log out of Windows and run (in c:\path_to_xampp\php)

pear config-show

Now you can see that the path has been updated :)

Solution 4

In windows 7 i use powershell.

you can set the PHP_PEAR_SYSCONF_DIR variable and then run a pear command. For Example:

$env:PEAR_CONFIG_SYSCONFDIR = 'c:\path_to_xampp\php'
pear install pear.phpunit.de/PHPUnit

Cheers Volker! PHP_PEAR_SYSCONF_DIR it is.

Works beautifully for a global PEAR install. But if there are multiple local PEARs, you need to patch pear.bat. See here for more: stackoverflow.com/a/10219809/508355

On Windows, edit your pear.bat to have the line IF "%PHP_PEAR_SYSCONF_DIR%"=="" SET "PHP_PEAR_SYSCONF_DIR=c:\dev\php" (or pointing to wherever your PHP installation actually is)
