Matching only Arabic and English Alphanumeric with one space allowed only

I have got a forum site and I am currently working on the final piece, the registration form and I want to validate the username. It should only contain Arabic and English alphanumerics and a maximum of one space between words.

I've got the english alphanumeric part working but not the Arabic nor the double spaces.

I am using the preg_match() function to match the username input with the RegEX.

What I currently have:

!preg_match('/\p{Arabic}/', $username) && !preg_match('/^[A-Za-z0-9]$/')
//this is currently inside and if statement, so if they both don't match then it is false.

You should put the unicode properties inside your regular regex because this can all be done with 1 regex. You also need to quantify that character class otherwise you only allow 1 character. This regex should do it.

^[\p{Arabic}a-zA-Z\p{N}]+\h?[\p{N}\p{Arabic}a-zA-Z]*$

Use the u modifier in PHP so unicode works as expected.

PHP Usage:

preg_match('/^[\p{Arabic}a-zA-Z\p{N}]+\h?[\p{N}\p{Arabic}a-zA-Z]*$/u', $string);
