The flags argument is optional and defaults to an empty string.

Characters in the flags argument will be sorted alphabetically when a Regex is constructed. Previously, the characters were stored in the order provided.

MongoDB\Driver\Exception\InvalidArgumentException is thrown if pattern or flags contain null bytes. Previously, values would be truncated at the first null byte.

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;
