$allowed = "/[^a-z\\040]/i"; - how also allow & sign

[johnsmith153]

I want to allow all letters and the & character

 

 

$allowed = "/[^a-z\\040]/i";

 

 

I am sure I need a slight change to the above line of code.

You start your character class with ^, which negates the entire class.. If you want to allow only letters and the ampersand character, then perhaps something along the lines of:

 

$allowed= '#^[a-z\x26]+$#i';
