I want to know how to remove special characters from url like:

 

product.php?id=--35

 

i want to remove all the special characters from url like ( ', " , - , /, etc) all special characters.

So you're concerned that someone can mess with your URLs and put all sorts of bad stuff into the "id" value?

 

Honestly, I think it's better to treat invalid values (like "--35") as invalid values, not try to somehow force them to be valid. Take the same action you would as if someone entered "id=foo" or "id=" or removed the id entirely.
