Codeigniter PHP getting option value

I've got a complicated re-population system that works, but it's cumbersome.

I've got a dropdown menu for a country of birth, and when the users submit the form it gets thrown in a database. The dropdown menu then gets repopulated with whatever is in the database if there is something.

I get the value from the database like this:

$birthplacecountry = (!set_select('birthplacecountry') && $birth_citizenship) ? $birth_citizenship[0]['birthplacecountry'] : (set_select('birthplacecountry') ? set_select('birthplacecountry') : '');

That works fine, as I've then got my options looking like this:

<option value="Afganistan" <?php if ($birthplacecountry == 'Afganistan') echo 'selected="selected"';?>>Afghanistan</option>
<option value="Albania" <?php if ($birthplacecountry == 'Albania') echo 'selected="selected"';?>>Albania</option>
<option value="Algeria" <?php if ($birthplacecountry == 'Algeria') echo 'selected="selected"';?>>Algeria</option>
<option value="American Samoa" <?php if ($birthplacecountry == 'American Samoa') echo 'selected="selected"';?>>American Samoa</option>

However, it's annoying having to compare $birthplacecountry to the name of the value manually. Is there a general way to compare something to the options value?

Some sort of functionality that works like: if ($birthplacecountry == this.option.value)

In codeIgniter, you should use Form helper to produce a select/dropdown, i.e.

$options = array(
    'Afganistan'  => 'Afganistan',
    'Albania'    => 'Albania',
);
echo form_dropdown('birthplacecountry', $options, 'Albania');

In this example, a dropdown with name birthplacecountry will be created and selected option will be Albania, the seconf one. The third parameter sets the selected option, so, when you want to repopulate the form with selected option, you can do something like this

echo form_dropdown('birthplacecountry', $options, set_select('birthplacecountry', $this->input->post('birthplacecountry') );
