While this works and is a correct solution,
just keep in mind that some cloud Redis options do not support the "key *" command - as it is very expensive.

A workaround to this is described here:

use Predis\Collection\Iterator;

$client = ...;
$pattern = 'foo*';

foreach (new Iterator\Keyspace($client, $pattern) as $key) {
    ...
}
