RegEx "/[^A-z]/"

[Flos]

Hello!

I want to make a validation for a string which can be only letters AND
space. for example "apple house", but not "apple3 house"

i have found

if (preg_match ("/[^A-z]/", $string)) return false
esle return true

this does not accept a space. i tried \s, \S. and [:space:] but it
didn't work.

I tried several tutorials, but my problem is not mentioned there. And to
say the true RegEx seem pretty difficult to me.

I apreciate any help,

Flos

sorry for spelling mistakes

It shouldn't do, you haven't included space in the character class. And you've
got a lot more than you probably want.

A-z is:

ABCDEFGHIJKLMNO PQRSTUVWXYZ[\]^_`abcdefghijkl mnopqrstuvwxyz

You said you wanted a space, not all whitespace.
What makes you think it "didn't work"? Prove it with an example.

/[^A-z]/ means match any string that contains a character other than the load
I posted above.

Sounds like you want:

/[^A-Za-z ]/

Or:

/[^a-z ]/i

Change your " to ' and use \s
