For a project I must save some binary data in the database. I start with some hexadecimal values like
A5 FF B3 23 DF
etc. This can be anything and the string can get quite long. From this string I take 2 chars every time and translate this hex code into a character. So I get a long string of strange looking chars (mostly displayed as squares on the screen). This is what I want to save into the MySQL database.
So I made a nice update query, nothing fancy... just UPDATE xyz SET abc = [BINARY STRING]
But the thing doesn't seem to work... I don't get an error message and when I echo the query and copy/paste it in MySQL administrator it seems to work fine (although the data is incorrect, because it's trying to insert the squares and all that stuff, not the actual char/code).
I tried escaping it, I've tried base64 stuff etc... the thing just won't update.
Is there anything I could have missed? Are there special ways to insert this kind of data into a MySQL database with PHP?
If more information is needed, please ask; I'll provide ;).
