有些字符会自动转义吗？

Question

I'm inputting some fields into a database. One had a value of

foto's

and when I checked in the $_POST[] where that was contained it had

foto\'s

does this happen automatically? I have (not yet) any escaping in my script.

Update: So it's the magic quotes that is doing it. The php.ini-file looked like this:

; Magic quotes
;

So I changed it to:

; Magic quotes
;

; Magic quotes for incoming GET/POST/Cookie data.
magic_quotes_gpc = Off

; Magic quotes for runtime-generated data, e.g. data from SQL, from exec(), etc.
magic_quotes_runtime = Off

; Use Sybase-style magic quotes (escape ' with '' instead of \').
magic_quotes_sybase = Off

; Use Sybase-style magic quotes (escape ' with '' instead of \').
magic_quotes_sybase = Off

But in phpinfo this is still on:

magic_quotes_gpc    On  On

Answer 1

This is probably magic quotes in action. Disable them immediately and then follow the usual best practices to properly escape user-supplied input depending on what you are going to do with it.
