Since you're using PHP, you can use a loop to generate the <option> elements:

<form method="POST">
  <select name="dropdown">
<?php
    for ($x=1; $x<=12; $x++) {
        echo '    <option value="' . $x . '">' . $x . '</option>' . PHP_EOL;
    }
?>
  </select>
  <input type="submit" value="Submit">
</form>

And to read the variable:

<?php
    if (isset($_POST['dropdown']) {
        // cast to integer to avoid malicious values
        $dropdown = (int)$_POST['dropdown'];
    }
?>

Another option using php

<?php

echo "<select name=\"numbers\">";
for($i = 1; $i <= 12 ; $i++){
echo "<option value=\"$i\">$i</option>";
}
echo "</select>"
?>

In HTML:

<select name="myDropDown">
  <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>
  <option value="11">11</option>
  <option value="12">12</option>
</select>

In PHP:

// Note: Perform input sanitizing and type checking as needed here...
$myVariable = $_POST["myDropDown"];

Naturally, there's more scaffolding around all of this which is omitted here for brevity. If there's more you need to know about any of that, please update the question to be more specific. As it stands now, it's difficult to determine your experience level with the technologies in question.
