How to replace specialcharacters?

Anon

Hey,
I have a form that inserts/updates data to a table.
How should I write if I want my field/string to replace specialcharacters.

In ASP I would gather the info this way
var information = Request.Form('information');

and replce the ' character this way
information= String(information);
information= information.replace(/'/g,"''");

How would this one look in PHP?

this was my main question, but I'm also wondering how to replace the special Swedish/german characters å, ä, ö.

Once again I was successful in ASP by writing this
var first = Request.Form("firstname");
var last = Request.Form("lastname");
first = String(first);
first = first.replace(/'/g,"");
first = first.replace(/[ao]/ig,"");
first = first.replace(/*/g,"%");
last = String(last);
last = last.replace(/'/g,"");
last = last.replace(/[ao]/ig,"");
last = last.replace(/*/g,"%");
This one gathers the Firstname and Lastname and then replaces å,ä,ö to a and o.
With this a user can search a name, say Jorgen Akesson and still get the result Jörgen Åkesson.

----> SO if anyone could help me out with these two questions, I would appreciate it a lot!

Hi Johan,

Try putting the following before the UPDATE/INSERT statement:

$information = htmlspecialchars($information)

see http://www.php.net/manual/en/function.htmlspecialchars.php for additional info.

Oops, forgot something...

$information = htmlspecialchars($information);

Second question:
I think your looking for this: http://nl.php.net/manual/nl/function.eregi-replace.php

Good luck!
