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;
