Fatal error: Uncaught PDOException: SQLSTATE[IM002] SQLDriverConnect: 0 [Microsoft][ODBC Driver Manager]
The data source name was not found, and no default driver was specified in C:\test.php:29
C:\test.php(29): PDO->__construct('odbc:Driver={Mi...')
With an older PHP version it worked.

Test script:

    // HEAD

    declare( strict_types = 1 );

    error_reporting( -1 );

    ini_set( 'html_errors', '0' );

    ini_set( 'display_errors', '1' );

    define( 'CORE_DIR', dirname( __FILE__ ) . DIRECTORY_SEPARATOR );

    header( 'Content-Type:text/plain' );

    // CODE


    extension_loaded( 'pdo_odbc' ) or trigger_error( 'The pdo odbc extension is required.', E_USER_ERROR );

    $database_path = CORE_DIR . 'test.accdb';

    file_exists( $database_path ) or trigger_error( 'Could not find database file.', E_USER_ERROR );

    $database = new PDO( 'odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)}; Dbq=' . $database_path );

    // $database = new PDO( 'odbc:Driver={Microsoft Access Driver (*.accdb)}; Dbq=' . $database_path . '; Uid=; Pwd=;' );

    // $database = odbc_connect( 'Driver={Microsoft Access Driver (*.mdb, *.accdb)}; Dbq=' . $database_path, '', '');

That works fine for me with current PHP 7.3.

Maybe there is a permission issue in your setup?

I tested it again, it works with PHP 7.3.23 x86. But I would like to use x64. When I try to use the current PHP version 7.4.11 x86 / x64, I get the following error: PHP Warning: 'vcruntime140.dll' 14.0 is not compatible with this PHP build linked with 14.16 in Unknown on line 0

Thanks for the swift feedback!

Apparently, you have a pretty old vcruntime140.dll; just download
the latest VC redistributable[1] and install it.
