Question

I have a piece of code where a variable can either be an array or just a string.

if(!is_array($relation['display_name']))
{
    // do something with $relation['display_name']
}
else
{
    foreach($relation['display_name'] as $display_name)
    {
        // do the same with $display_name
    }
}

This of course works – but it’s not very nice. And I would have to do it a lot of times. Is there a better way of doing this?

You can do it like this:

foreach((array)$relation['display_name'] as $display_name) {
     // do something with $display_name
}
