根据存储的mysql值选择Select Option

I have an edit page for user profiles. One option is 'Country' with all the countries listed in the php file (countries are not loaded from database). On the user edit profile page I want to be able to select the currently stored option value from the list.

I could do this:

<option value="Afghanistan" <?php if ($results['country'] == 'Afghanistan') echo 'selected';?> >Afghanistan</option>
<option value="Albania" <?php if ($results['country'] == 'Albania') echo 'selected';?> >Albania</option>
<option value="Algeria" <?php if ($results['country'] == 'Algeria') echo 'selected';?> >Algeria</option>
<option value="American Samoa" <?php if ($results['country'] == 'American Samoa') echo 'selected';?> >American Samoa</option>
 // The rest of the countries here :(..

Is there a better (cleaner) way to do this without putting all the countries into the db?

There is, iterate a $countries array using a foreach loop, and generate the options, match against the country value to find the selected.

Example:

$countries = array("Afghanistan", "Albania", "Algeria", "American Samoa");

foreach ($countries as $country) {
    echo "<option value='$country'";
    if ($country == $results["country"]) {
        echo " selected";
    }
    echo ">$country</option>
";
}

Outputs (for $results["country"] = "Albania"):

<option value='Afghanistan'>Afghanistan</option>
<option value='Albania' selected>Albania</option>
<option value='Algeria'>Algeria</option>
<option value='American Samoa'>American Samoa</option>

If I understand what you want right, I suggest using a foreach loop:

$countries = array(
    "Afghanistan",
    "Albania",
    "Algeria",
    "American Samoa"
    // ...
);

foreach($countries as $country) {
    echo '<option value="'.$country.'"';
    if($country == $results['country']) {
        echo ' selected="selected"';
    }
    echo '>'.$country.'</option>';
}

In addition to the other answers if you can't store the countries in a DB you may consider storing them in a text file. Read them in and iterate over them. This will make it easier to add new countries without changing code. Just a thought.
