Exclude symbol from regular expression PHP

I'm currently using the following to clean a string from symbols/unknown characters:

$title = preg_replace("/[^a-zA-Z0-9-]/", " ", $title);

However, I don't want to remove '&' from the string

Can someone help me out?

Thanks!

the ^ at the start of a character class: [^... ] means that all chars in that class should be excluded from matching. In your case this chars shouldn't be removed. So add & to the class like this:

$title = preg_replace("/[^a-zA-Z0-9-&;]/", " ", $title);
