How can multiple selectbox values be processed in PHP after submission?

When processing multiple selectbox values in PHP after submission, the selected values can be accessed as an array in the $_POST or $_GET superglobals. You can loop through this array to handle each selected value individually or perform operations on the array as a whole. 

// Assuming the selectbox in the HTML form has the name attribute set to 'selectbox[]'
if(isset($_POST['selectbox'])) {
    $selectedValues = $_POST['selectbox'];
    
    foreach($selectedValues as $value) {
        // Process each selected value here
        echo $value . "<br>";
    }
}
