Would this match letters only no matter case?

I wanna use this in a preg_match and want to know if this will match to only strings that contain case insensitive letters

preg_match("/[^a-z]/i",$str)

sure, that would work, though opposite of what you're asking.  If it finds anything that is not a-z or A-Z it will return true.  So true means the string has more than just letters, false means that it IS only a-z or A-Z

 

if you want to have it return true if the string is only case insensitive letters, you would need to do this:

 

preg_match("/^[a-z]+$/i',$str);

I got it to do what I needed it to do without even full knowing what I needed it to do lol

It worked the way I wanted it to the way I wrote it. Thankyou for the help and explanation
