Answer 1

This should work :

preg_match("(^[\x{0600}-\x{06FF}]*$)", 'فارسی');

And also you can use all these forms for Persian language :

Persian Alphabet

فارسی

/^([\x{0600}-\x{06EF}])+$/

Persian Numbers

۱۲۳۴۵۶۷۸۹۰

/^([\x{06F0}-\x{06F9}])+$/

Persian simple text with space and half-space

اگر زمان و مکان در اختیار ما بود، ۱۰ سال پیش از طوفان نوح عاشقت می‌شدم

/^([\x{0600}-\x{06FF}| |\x{200C}])+$/
