    This matches with any fieldName that includes the string:
    $mongoRegex = new MongoDB\BSON\Regex("$string", "i");

    This matches with any fieldName that STARTS with the string:
    $mongoRegex = new MongoDB\BSON\Regex("^$string", "i");

    $cursor = $collection->find( [ 'fieldName' => $mongoRegex ] );

    $docs = [];

    foreach($cursor as $doc){
    $docs[] = $doc;
    }

    return $docs;
