Regular Expression Arabic characters and numbers only

Question

I want Regular Expression to accept only Arabic characters, Spaces and Numbers.

Numbers are not required to be in

Answer 1

In PHP, use this:

preg_replace("/\p{Arabic}/u", 'x', 'abc123ابت');// will replace arabic letters with "x".

Note: For \p{Arabic} to match arabic letters, you need to pass u modifier (for unicode) at the end.
