Re: [PHP] Serialised Data DBs
Yes, you would need to. serialize() does not encode any of the variable data. -Rasmus On Tue, 30 Jul 2002, Danny Shepherd wrote: Hi, Is it necessary to perform addslashes() on serialised data before inserting it into a database?

Re: [PHP] Serialised Data DBs
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?
