    Assuming we’re at the WordPress URL “http://www.example.com/client/?details=value1&type=value2&date=value3″…

    Note the use of esc_url() before outputting the link.

    // This would output '/client/?type=value2&date=value3'
echo esc_url( remove_query_arg( 'details' ) );

// This would output '/client/'
$arr_params = array( 'details', 'type', 'date');
echo esc_url( remove_query_arg( $arr_params ) );

    When you want to manipulate a URL that is not of the page your script is in, add the targeted URL in the second parameter as below. The use of esc_url() is not required here (though encouraged), because the value is known to be safe:

    // This would output 'http://www.example.com/2014/03/11/'
echo esc_url( remove_query_arg( 'details',  'http://www.example.com/2014/03/11/?details=value1' ) );

// This would output 'http://www.example.com/2014/03/11/?type=value2&date=value3'
echo esc_url( remove_query_arg( 'details',  'http://www.example.com/2014/03/11/?details=value1&type=value2&date=value3' ) );

// This would output 'http://www.example.com/2014/03/11/'
$arr_params = array( 'details', 'type', 'date');
echo esc_url( remove_query_arg( $arr_params, 'http://www.example.com/2014/03/11/?details=value1&type=value2&date=value3' ) );
