Question

I am contemplating taking the next step with my PHP applications and making the option fields dynamic. That would open the doors for more automation.

I have drop downs throughout my project, they are used to select a specific user and I update them manually when a new user is added (which is also a manual process). But if i take the first step and make these drop downs become populated by a MySQL Database, then i can move on to dynamic user creation.

I know how I can achieve this, but I am curious about some other alternatives (If there is any).

Here is what I would do..

$query = ** MySQL Select * From Database Query **

echo '<select name="usernames">';

while($row == mysql_fetch_array($query))
{
     echo '<option>' . $row['username'] . '</option>';
}

echo '</select>';

So my questions is, would you do this differently? And why? Thanks!

What you are doing will work fine. I like to make it into a function so that if I ever need that dropdown on another page I dont have to write a lot of code over again.

function userDD()
{
   $query = ** MySQL Select * From Database Query **
   $html = '<select name="usernames">';

   while($row == mysql_fetch_array($query))
   {
        $html .= '<option>' . $row['username'] . '</option>';
   }

   $html .= '</select>';

   return $html;
}

This code does exactly what your code does except it doenst use echo. Instead you use a variable ($html) to store all of the data then when you are done you return it.
