How to set a text input control value through REST api

//Parameter1 is the Input Control ID (Singlue Value Item as Text)

        $controls = array(
            "Parameter1" => "Laravel"
        );
        $data = $rs->runReport($sample_report, 'html', NULL, $controls);
    
Or,
    
        $controls = array(
            "Parameter1" => array("Laravel")
        );
        $data = $rs->runReport($sample_report, 'html', NULL, $controls);
    
None of the above work.
