    <?php
    $serverName = "serverName\sqlexpress";
    $connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password" );
    $conn = sqlsrv_connect( $serverName, $connectionInfo);
    if( $conn === false ) {
         die( print_r( sqlsrv_errors(), true));
    }

    $sql = "UPDATE Table_1 SET data = ( ?) WHERE id = 100";

    $data = fopen( "data://text/plain,[ Lengthy content here. ]", "r");
    $params = array( &$data);

    // Prepare the statement. Use the $options array to turn off the
    // default behavior, which is to send all stream data at the time of query
    // execution.
    $options = array("SendStreamParamsAtExec"=>0);
    $stmt = sqlsrv_prepare( $conn, $sql, $params, $options);

    sqlsrv_execute( $stmt);

    // Send up to 8K of parameter data to the server
