Are there any specific considerations or adjustments that need to be made when writing PHP code that interacts with dropdown lists in Opera?

When interacting with dropdown lists in Opera, it is important to ensure that the PHP code used to populate or interact with the dropdown list is compatible with Opera's browser specifications. One common issue is that Opera may not handle certain JavaScript events or functions in the same way as other browsers, so it is important to test the code thoroughly in Opera to ensure it functions as expected. Additionally, it may be necessary to make adjustments to the code to account for any specific quirks or differences in how Opera handles dropdown lists compared to other browsers. 

// Example PHP code snippet for interacting with a dropdown list in Opera

// Populate the dropdown list with options
$options = array("Option 1", "Option 2", "Option 3");

echo "<select>";
foreach ($options as $option) {
    echo "<option>$option</option>";
}
echo "</select>";

// Retrieve the selected option from the dropdown list
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $selected_option = $_POST['dropdown'];
    echo "Selected option: $selected_option";
}
