下拉框中选项选择属性的文本

Question

I need to send an email notification of fields in a submitted form.

My question as follows is regarding the HTML select tag in the form.

<select id="country_code" name="country_code">
    <option value="" selected disabled>Country</option>
    <option value="AR">Argentina</option>
    <option value="BR">Brazil</option>
    <option value="CG">Congo</option>
    <option value="ZW">Zimbabwe</option>
</select>

Below I get the country code of a selected option:

$country_code = $_POST["country_code"];

How to get using PHP the text of the selected value in option tag (i.e. the country name)?

Note: I can't use MySQL, or JavaScript, and I can't change the select box values.

HTML:

<select id="country_code" name="country_code">
    <option value="" selected disabled>Country</option>
    <option value="AR">Argentina</option>
    <option value="BR">Brazil</option>
    <option value="CG">Congo</option>
    <option value="ZW">Zimbabwe</option>
</select>

PHP:

<?php
if(isset($_POST['formSubmit'])){ 



    $countrySelection = $_POST['country_code'];

    $countrycode_list = array('AF', 'AX', 'AL', 'DZ', 'AS', 'AD', 'AO', 
    'AI', 'AQ', 'AG', 'AR', 'AM', 'AW', 'AU', 'AT', 'AZ', 'BS', 'BH', 'BD',

    'KE', 'KI', 'KP', 'KR', 'KW', 'KG', 'LA', 'LV', 'LB', 'LS', 'LR', 'LY',

    'NF', 'MP', 'NO', 'OM', 'PK', 'PW', 'PS', 'PA', 'PG', 'PY', 'PE', 'PH',

    'US', 'UM', 'UY', 'UZ', 'VU', 'VE', 'VN', 'VG', 'VI', 'WF', 'EH', 'YE', 
    'ZM', 'ZW');

    $ISO3166 = NULL;
    //Loop all country codes
    foreach ($countrycode_list as $countrycode) {
        $locale_cc = Locale::getDisplayRegion('-' . $countrycode, 
        $countrySelection);

        if (strcasecmp($country_name, $locale_cc) == 0) {
            $ISO3166 = $countrycode;
            break;
        }
    }
//return NULL if not found or country code
return $ISO3166;
}
