note 103717 added to function.serialize

Hello, I wanted to serialize a complex array (an array of arrays with a few levels, it's a configuration file) and I think I have found a bug in the 'serialize' function. I work with PHP 5.2.5 (from SLES 10). I had as result always the string "N;". This value corresponds to NULL value. So I did my own 'serialize' function. Here it is in case you had the same problem. <?php # Function which returns serialization string for a scalar value private function ser_value($value) { if (is_null($value)) { return "N"; } elseif (is_bool($value)) { return $value ? "b:0":"b:1"; } elseif (is_integer($value)) { return "i:".$value; } else { return "s:".strlen($value).":\"".$value."\""; } } # Recursive function which returns serialization string for an array function serialize_data($array) { $n = count($array); $result = "a:".$n.":{"; $i = 1; foreach ($array as $key => $value) { $result .= ser_value($key).";"; $result .= (is_array($value)) ? serialize_data($value) : ser_value($value).";"; } $result .= "}"; return $result; } ?> Greetings from Spain José M.
