echo '
';
echo iconv_substr($str, 1, 1, 'UTF-8'); //Truncate by the number of characters instead of bytes
print_r(iconv_get_encoding()); //Get the current page encoding information
echo iconv_strlen($str, 'UTF-8'); // Get the string length of the set encoding

for ($i=0;$i

## echo $utf;

If your PHP file is GB, then the following code can work:

　

##　$str='I love Baidu';

#　　for ($i=0;$i
