Yes, it'd be really smart to. If any of the data in the serialized string has a ' or " in it, it could break your query. Or the user being able to enter a ' or " into the data could open you to SQL attacks.
You want to do addslashes() on the result of serialize(), not the content going into it, too. PHP will introduct double quotes around any strings that are serialized. These should be escaped or they could end up breaking your query. Note that you don't have to do stripslashes() on the serialized string when you pull it out. ---John Holmes... ----- Original Message ----- From: "Danny Shepherd" <[EMAIL PROTECTED]> To: "PHP-General" <[EMAIL PROTECTED]> Sent: Tuesday, July 30, 2002 2:56 PM Subject: [PHP] Serialised Data & DBs > Hi, > > Is it necessary to perform addslashes() on serialised data before inserting > it into a database? > > Thanks, > > Danny. > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
