Node Js Php Serialize Data
You need to escape a serialized string in a manner appropriate for your DB, just as you do for any string. For example, mysqlrealescapestring or prepared statements in the case of MySQL.If you base64encode the serialized string then you will probably obviate escaping regardless of database it since the base64 code table uses only ASCII’s alpha, numeric, + and / characters.
But that doesn’t mean it’s a good solution.I think base64encode not a good replacement for using your DB’s correct escape procedures for efficiency reasons. Sometimes code fragments found on the web will work as drop-in but are a poor substitute for understanding.
I agree with Shimon in this, there is no reason why adding that layer of base64 encoding AFTER the serialization occurs, should resolve a problem with the unserialization, unless, and that’s not been specified in here, the serialized data was messed up by some escaping function, encoding conversion, etc, before or after being stored in a database or similar.I understand that in that case, preventing the data from containing characters suscettible to escaping such as quotes, would be of help, but it’s not a general case. Excellent solution. This is definitely a good way to go. I was thinking of using the pregreplace function to replace any single quotes, double quotes, semicolons, or colons with a set of characters that is unlikely to be used in the string. For instance:$variable = pregreplace(‘ ’ ’, “SINGLEQUOTE”, $variable);$variable = pregreplace(‘ ’ ’, “DOUBLEQUOTE”, $variable);$variable = pregreplace(‘ ’ ’, “SEMICOLON”, $variable);$variable = pregreplace(‘ ’ ’, “COLON”, $variable); $variable = serialize($variable);The downside to this solution is that it is a lot of work for a similar result and the unserialize function must utilize the same code but in reverse.
I haven’t yet tested the two but speed can definitely be a factor in which direction you would want to go. Also, with the pregreplace solution, you must use a string that will NOT be used in the variable at all or strange results will occur.
Again, thanks for sharing your solution. I believe it may be a way that I will go with my code and its certainly a clever use of the base64encode/decode functions. Thank you for you help!Although your solution wasn’t quite enough to get it to work for me it was definitely part of the solution. I was trying to store the serialized string to my sql server db in a text field.

After I realized that the ” were causing problems with unserialize and used the base64encode I then realized that the string was being truncated when retrieving it from the db. The easiest way I found to get around this was to make these 2 changes in php.inimssql.textlimit = mssql.textsize = They were set by default to 4096 and were commented out so remember to remove the; too.Hope this helps someone. Dear All,i have found that the serialize value stored to database is converted to some other way format. Since the serialize data store quotes marks, semicolon, curly bracket, the mysql need to be save on its own, So it automatically putting “backslash” that comes from gpcmagicquotes (CMIIW).

So if you store a serialize data and you wanted to used it, in the interface you should used htmlentitydecode to make sure you have the actual format read by PHP.here was my sample:$ser = $data-serialization; // assume it is the serialization data from database$arrser = htmlentitydecode($ser);nb: i’ve try it and it works and be sure avoid this type to be stored in tables (to risky). This way can solve the json format stored in table too. Another thing to add to your list of misbehaving characters – the backslash.If you’re storing PHP objects in the DB that have namespaces, when you serialize them, they will be serialized in the form of “namespaceclassName” and the same for any embedded objects that are properties of the class.This will totally hose your unserialize op because the backslashes get stripped out on the insert/update.Thanks for the article.

My objects were serializing/unserializing from the SESSION just fine, but trying to get them back out of the DB was not working.I also have to disagree with Thomas above – this is not spurious and the solution makes perfect sense. You cannot unserialize a base64 encoded string that you retrieve from the database – it has to be decoded first!
