How can PHP developers ensure that their form submissions trigger the desired actions, such as displaying specific content based on radio button selections?

To ensure that form submissions trigger the desired actions in PHP, developers can use conditional statements to check the values of form inputs and display specific content based on those values. For example, if a radio button is selected, the developer can use an if statement to determine which content to display based on the selected value. 

if(isset($_POST['submit'])){
    $radio_value = $_POST['radio_button'];
    
    if($radio_value == 'option1'){
        echo "Content for option 1";
    } elseif($radio_value == 'option2'){
        echo "Content for option 2";
    } else {
        echo "Default content";
    }
}
