Windows Registry Wrapper

A small library for accessing and manipulating the Registry on Microsoft Windows systems. For that one time that you need to access the Windows Registry in a PHP application.

This library can be (and has been) used in production code, but please consider reading the disclaimer below before using.

Features

• Read and write access to any hive, key, or value in the registry (that you have permissions to)
• Automatic conversion between all registry value data types to PHP scalar types
• Lazy-loaded iterators over lists of values and recursive iterators over keys and subkeys
• Ability to connect to registries on remote computers using a remote WMI (Windows Management Instrumentation) connection (see Microsoft's docs on how to connect to WMI remotely for details)

Requirements

• Microsoft Windows (Vista or newer) or Windows Server (Windows Server 2003 or newer)
• PHP com_dotnet extension

Installation

Use Composer:

> composer require coderstephen/windows-registry:~0.9

Examples

Below is an example of creating a new registry key with some values and then deleting them.

use Windows\Registry;

$hklm = Registry\Registry::connect()->getLocalMachine();
$keyPath = 'Software\\MyKey\\MySubKey';

// create a new key
try
{
    $mySubKey = $hklm->createSubKey($keyPath);
}
catch (Registry\Exception $e)
{
    print "Key '{$keyPath}' not created" . PHP_EOL;
}

// create a new value
$mySubKey->setValue('Example DWORD Value', 250, Registry\RegistryKey::TYPE_DWORD);

// delete the new value
$mySubKey->deleteValue('Example DWORD Value');

// delete the new key
try
{
    $hklm->deleteSubKey($keyPath);
}
catch (Registry\Exception $e)
{
    print "Key '{$keyPath}' not deleted" . PHP_EOL;
}

You can also iterate over subkeys and values using built-in iterators:

foreach ($key->getSubKeyIterator() as $name => $subKey)
{
    print $subKey->getQualifiedName() . PHP_EOL;
}

foreach ($key->getValueIterator() as $name => $value)
{
    printf("%s: %s\r\n", $name, $value);
}

Disclaimer

Messing with the Windows Registry can be dangerous; Microsoft has plenty of warnings about how it can destroy your installation. Not only should you be careful when accessing the Registry, this library is not guaranteed to be 100% safe to use and free of bugs. Use discretion, and test your code in a virtual machine if possible. I am not liable for any damages caused by this library. See the license for details.
