Populate a Drop down box from a mySQL table in PHP

You can use the PHP MySQLi extension to connect to a MySQL database and retrieve the data from a table to populate a drop-down box. Here's an example:

<?php
  
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT id, name FROM mytable";
$result = $conn->query($sql);

echo "<select>";
while ($row = $result->fetch_assoc()) {
  echo "<option value='" . $row['id'] . "'>" . $row['name'] . "</option>";
}
echo "</select>";

$conn->close();
?>

You can use the above code snippet to populate your dropdown box. Replace "mytable" with the name of your table, and "id" and "name" with the appropriate column names from your table.
