PHP substr波斯语字符串以问号结尾

Question

In PHP when I want to substr the Persian string 'حروف فارسی برای امتحان', and it appends the question mark at the end of string.

This is my code:

$a = 'حروف فارسی برای امتحان'; echo substr($a,0,10);

And the problem is حروف �

Anyone has any suggestion or solution for this regards? much appreciated.

Answer 1

use mb_substr($a,0,10,'utf-8') instead of substr() for Persian and Arabic characters

Answer 2

PHP does not have multi-byte character support by default. You have to use mb_* functions, like

mb_substr()
