Okay, this is my first post, so bear with me. I am coding a blog-type site, and I'm trying to filter out some HTML tags from files. I'm using the callback of the filter_var() function. I get a:
Fatal error: Call to undefined function filter_var() in /home/benjamin/public_html/homeofben/blogview.php on line 18
I don't know why the function wouldn't exist, as I am using PHP 5 and www.w3schools.com says the filter_var() function exists in PHP 5. However, I have a feeling this is an obvious thing. Help would be appreciated.
