get list of ODBC data source in local pc using PHP

I'm looking for a way to get a li开发者_如何学Cst of ODBC data sources in local PC using PHP. How can I achieve that?

If I assume that you're running on windows

User defined ODBC connections are stored under HKEY_CURRENT_USER\Software\ODBC\ODBC.INI

System defined ODBC connections are stored under HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI

ODBC drivers are defined under HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI

So you need some trick with php to read from registry like this one or this one

If I assume that you are on unix/linux then

User defined ODBC connections are stored under /etc/odbc.ini

System defined ODBC connections are stored under /home/username/.odbc.ini

ODBC drivers are defined under /etc/odbcinst.ini

All of them are INI-like syntax text files.

PHP has built-in connection support for MySQL so a ODBC connection is not required. ODBC would be needed for any database environment not supported by PHP.

    define('HKEY_LOCAL_MACHINE', 0x80000002); 
    $computer = '.'; 
    $reg = new COM("winmgmts:{impersonationLevel=impersonate}!\\\\$computer\\root\\default:StdRegProv"); 
    $key_path = 'SOFTWARE\ODBC\ODBCINST.INI'; 
    $sub_keys = new VARIANT(); 
    $reg->EnumKey(HKEY_LOCAL_MACHINE, $key_path, $sub_keys); 

    foreach($sub_keys as $sub_key){ 
        echo $sub_key . "\n"; 
    }
