special chars

[saku]

lets say, that the user may input this string in the textbox:
1;2'3"4>5<6?7&8%9/10\11

what functions do i have to call
1) before inserting this string in database?

2) before outputing it to textbox (after selecting from db), of course i want to see the same string as input

take a look here:

you shouldn't need to do anything when you display something selected from the database I think, since the escapes are there to mask certain characters, they shouldn't be entered into the database at all.
