  if (is_array($jsonhome)) {
                foreach ($jsonhome as $query) {
                    foreach ($query['results']['place'] as $places) {


                        if (is_array($places['country'])) {
                            echo "Country:
";
                            echo "Content: " . $places['country']['content'] . "

";
                        }

                        if (is_array($places['admin1'])) {
                            echo "State:
";
                            echo "Content: " . $places['admin1']['content'] . "

";
                        }

                        if (is_array($places['admin2'])) {
                            echo "District/City:
";
                            echo "Content: " . $places['admin2']['content'] . "

";
                        }
                    }
                }
            }

    $location_data['user_current_country'] = $places['country']['content'];

            $this->load->view('header_register', $location_data);
            $this->load->view('body_complete_register', $location_data);

So in your controller you want to build an array of options for your <select>. Something like

//Build array of country options
$aData['countryOptions'] = array();
foreach ($jsonhome as $query) {
    foreach ($query['results']['place'] as $places) {
        $aData['countryOptions'][] = $places['country']['content'];
    }
}

$this->load->view('body_complete_register', $aData);

Then in your view you can use the form_dropdown function providing you have the form helper loaded

$this->load->helper('form');
echo form_dropdown('countries', $countryOptions);

Of if you don't want to use the helper you could do

<select name="countries" id="countries">
    <?php foreach($countryOptions as $key => $countryName) { ?>
        <option value="<?php echo $key ?>"><?php echo $countryName ?></option>
    <?php } ?>
</select>

Please note that you shouldn't be echoing anything out in the controller. The controller is just for passing data between models, libraries and views
