number of html select fields based on MySQL response

Ok, here's my latest dilemma.  If anyone has any suggestions, I would love to hear them.  I am not looking for someone to code this for me, just a point in the right direction.

 

I have a value in my MySQL database that is a number between 1 and 50 ($number_value).  When the page loads, I want to use that value to create a dropdown list from 1 to $number_value.

 

I could create a script that checks for $number_value for each possible situation, but that would be a pretty long and probably not the most efficient.  Any other ideas?

 

So you know what I am talking about, this is just a text representation:

If $number_value is 5, echo:
<option value=“1">1</option>
<option value=“2">2</option>
<option value=“3">3</option>
<option value=“4">4</option>
<option value=“5">5</option>

If $number_value is 3, echo:
<option value=“1">1</option>
<option value=“2">2</option>
<option value=“3”>3</option>

If $number_value is 10, echo:
<option value=“1">1</option>
<option value=“2">2</option>
<option value=“3”>3</option>
<option value=“4">4</option>
<option value=“5">5</option>
<option value=“6”>6</option>
<option value=“7">7</option>
<option value=“8">8</option>
<option value=“9”>9</option>
<option value=“10”>10</option>

this is the whole point of variables and control structures in programming. you can set a variable to any value, from wherever you want, and use control structures, such as a loop, to test/use the value that's in the variable to determine what to do.

foreach(range(1,$number_value) as $value){
    echo "<option value='$value'>$value</option>\n";
}
