How can the default case be implemented in a PHP switch statement?

To implement a default case in a PHP switch statement, you can simply add a "default" case at the end of the switch statement. This default case will be executed if none of the preceding cases match the given value. 

switch ($variable) {
    case 'value1':
        // code to be executed if $variable is 'value1'
        break;
    case 'value2':
        // code to be executed if $variable is 'value2'
        break;
    default:
        // code to be executed if $variable does not match any of the cases
}
