How can multiple options selected in a form be evaluated in PHP?

When multiple options are selected in a form (such as checkboxes or a multi-select dropdown), the selected values are sent as an array in PHP. To evaluate these selections, you can use the $_POST superglobal array to access the array of selected values and loop through them to perform any necessary actions. 

// Assuming the form has checkboxes with name attribute as an array (e.g. <input type="checkbox" name="options[]">)
if(isset($_POST['options'])) {
    $selectedOptions = $_POST['options'];
    
    foreach($selectedOptions as $option) {
        // Perform actions based on the selected options
        echo "Selected option: " . $option . "<br>";
    }
}
