How can PHP developers ensure that all selected options are properly captured and processed when using a multiple select dropdown in a form?

When using a multiple select dropdown in a form, PHP developers can ensure that all selected options are properly captured and processed by accessing the selected values as an array in the PHP script that handles the form submission. This array will contain all the selected options, which can then be processed or stored as needed. 

// Assuming the form has a select dropdown with the name attribute set to "options[]" for multiple selection

if(isset($_POST['submit'])){
    // Access the selected options as an array
    $selectedOptions = $_POST['options'];

    // Process or store the selected options
    foreach($selectedOptions as $option){
        // Process each selected option
    }
}
