control statment if else

[hmvrulz]

i am confused to write a if statement

$action = 'show';
if($action = "show" or "edit" or "delete")
{
echo 'valid actions';
}else {
echo 'Invalid Action';
}

how to equate to the give text ??

Heres what you are after:

$action = 'show';

if ($action == 'show' OR $action == 'edit' OR $action == 'delete') {
	echo 'valid actions';
} else {
	echo 'Invalid Action';
}

Theres also other possibilities to achieve the same:

$action = 'show';

switch($action) {
	case 'show':
	case 'edit':
	case 'delete':
		echo 'valid actions';
	break;

default:
	echo 'Invalid Action';
break;
}

and..

$action = 'show';
$actions = array('show','edit','delete');

if (in_array($action,$actions)) {
	echo 'valid actions';
} else {
	echo 'Invalid action';
}

Second one(switch statement) is the best way because you'll probably do more than just print 'valid actions':

$action = 'show';

switch($action) {
	case 'show':
		// code for the show
	break;

case 'edit':
	// code for the edit
break;

case 'delete':
	// code for the delete
break;

default:
	echo 'Invalid Action';
break;
}
