$str = "This is a string containing 中文 characters. Some more characters - 中华人民共和国 ";
How do I detect chinese characters from this string and print the part which starts with the first character and ends with "-"? (it would be "中文 characters. Some more characters -").
Thank you!

I've solved this problem using preg_match and regular expressions:
$str = "This is a string containing 中文 characters. Some more characters - 中华人民共和国 ";
preg_match(/[\x{4e00}-\x{9fa5}]+.*\-/u, $str, $matches);

Is PHP storing this as Unicode? If so, at worst you could step through the string, character by character, until you hit those within the Chinese range.
