Using a .txt document within a select tag

[amstin213]

I have an assignment that I need to use a select tag to list three cities. I know how to code in html for a select tag.
This is what I have already working

<select name="city" size="1">
        <option value="0">-</option>
        <option value="Chicago">Chicago</option>
        <option value="Detroit">Detroit</option>
        <option value="Toronto">Toronto</option>
    </select>

Now what I need is the same results ^^ that gives you but by using a seperate .txt file for the cities. This is the code I have written. I know that the read file code is working fine. What I can't figure out is how to input the information in the select tag. I am sure, I am having a simple syntax issue but I really need to get this figured out.

$filename = 'data/'.'cities.txt';
 
        $lines_in_file = count(file($filename));
 
        $fp = fopen($filename, 'r');   
 
        for ($ii = 1; $ii <= $lines_in_file; $ii++)
        {
            $line = fgets($fp);  
            $city = trim($line);
 
            print"<select  size='1'>;
                '$_POST['$city']';     
                </select>";
        }
 
        fclose($fp);

Thanks for the help!

Please use code tags when posting code.

On line 13, why are you printing out the city from the post array? Just use $city. The $_POST array is to retrieve data that was passed to the page from a form.

It's been a couple of years since I did anything php or html for that matter, but if your data file had each city on its own line in the file, then you might try something like below.

$out = "<select name='city' size='1'><br />"
     . "<option value='0'>--</option><br />";
 
while(($buf = fgets($fp)) !== FALSE)
{
   $out .= "<option value='" 
        . trim($buf)
        . "'>"
        . trim($buf)
        . "</option><br />";
}  
 
if(!feof($fp))
{
   fclose($fp);
   exit("FILE READ ERROR: " . __LINE__);
}
 
$out .= "</select>";
echo $out;
