PHP下，截取中文字符串

One Chinese char in
UFT-8 encoding holds 3 bytes, and let's suppose that your string is encoded by 'UTF-8', and you've already set your page's encoding method is 'UTF-8',
then the following lines will make it:

$match->homegroup = '丙組';
echo substr($match->homegroup, 0, 3); // works, will output '丙' , but not good

echo mb_substr($match->homegroup, 0, 3); // works, will output '丙' , but not good

echo mb_substr($match->homegroup, 0, 1, "UTF-8"); // works, will output '丙'

Just stop here, since it get the work done. And will be back soon!
