I am trying to create a function to clean up variables that are user
inputted from a form.  I am not getting this script to work.  Can anyone
help.

---Start Script---
function cleaner($var)
{
trim(strip_tags(ucfirst(addslashes($var))));
}

$var = "abc's";

echo $var;
---End Script---

When I run the above script it produces nothing. Instead of a result of
"Abc\'s".
