Safe to use strpos with UTF-8 strings?

Question

I have a bunch of strings with different charsets. The $charset variable contains the charset of the current string.

$content = iconv($charset, \'UT         


        

Answer 1

Functions like strlen() count bytes, not characters.

See the notes in the PHP Manual for details:

Note:

strlen() returns the number of bytes rather than the number of characters in a string.

use the mb_* functions if you're working with UTF-8, unless you have the php.ini setting mbstring.func_overload enabled to overload the standard strops(), strlen(), substr(), etc functions... then strlen() will count characters
