How can the value of an option in a select box be retrieved in PHP?

To retrieve the value of an option in a select box in PHP, you can use the $_POST superglobal array to access the selected option value. This value is sent to the server when the form containing the select box is submitted. You can then use this value in your PHP code for further processing. 

// Assuming the select box has a name attribute of 'mySelect'
if(isset($_POST['mySelect'])){
    $selectedValue = $_POST['mySelect'];
    echo "Selected option value: " . $selectedValue;
}
