How can PHP be used to query software versions, such as Backup Exec, on a Windows XP or Windows 2003 system?

To query software versions, such as Backup Exec, on a Windows XP or Windows 2003 system using PHP, you can utilize the Windows Management Instrumentation (WMI) functionality in PHP. By connecting to the WMI service on the target system, you can run queries to retrieve information about installed software versions.

<?php
$wmi = new COM('winmgmts:{impersonationLevel=impersonate}!\\\\.\\root\\cimv2');
$software = $wmi->ExecQuery('SELECT * FROM Win32_Product WHERE Name LIKE "%Backup Exec%"');

foreach ($software as $app) {
    echo 'Software Name: ' . $app->Name . '<br>';
    echo 'Version: ' . $app->Version . '<br>';
    echo 'Vendor: ' . $app->Vendor . '<br><br>';
}
?>
