What is the significance of using $_POST['select1'] in the PHP code provided?

Using $_POST['select1'] in the PHP code provided allows the script to access the value selected in a form dropdown menu with the name 'select1'. This is significant because it enables the PHP script to process and manipulate the selected value as needed. By using $_POST['select1'], the script can effectively handle user input from the form and perform actions based on the selected option. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $selectedOption = $_POST['select1'];
    
    // Process the selected option here
    echo "You selected: " . $selectedOption;
}
?>

<form method="post">
    <select name="select1">
        <option value="option1">Option 1</option>
        <option value="option2">Option 2</option>
        <option value="option3">Option 3</option>
    </select>
    <input type="submit" value="Submit">
</form>
