Form validation in PHP

When someone enters a string similar to this in my address input field:

Some street 98, 1'st floor.

I get an error due to the ' char. It's substituted by / and a space!
This is no good...

Does anyone have the valid php ereg function to disable or replace the illigal chars like ' & // $ etc etc... ?

If someone enters something like this in a form that submits it to a php page, it errors on me big time.

try addslashes();

example

<? php

echo "This is correct field value: ".addslashes($_POST["form_field"]);

?>

Edited: there is space between '<?' and 'php' - just remove it to get it work

Edited 2: whe your form method is GET then change $_POST to $_GET
