使用数组中的值作为switch-case键

Question

I’m working on an app, and I’m stuck.

I want to do foreach inside switch like this:

<?PHP
$gtid = $_GET['id'];
// ID(key) => value
$dbs  = array(
    "ZTI10" => "Example1",
    "O1JTQ" => "Example2",
    "4V1OR" => "Example3"
);

switch($gtid){

foreach ($dbs as $key => $value) {

    case $key:
        echo "On ID $key is $value";
        break;

  }
}
?>

Is that even possible? Or is there any other way to do what I want here?

Thanks in advance.

Answer 1

if doesn't even need a loop

if (isset($dbs[$_GET['id']])) {
    echo sprintf('On ID %s is %s', $_GET['id'], $dbs[$_GET['id']]);
}
