/*** Intercept a Chinese string **/function msubstr ($ str, $ start = 0, $ length, $ charset = "UTF-8", $ suffix = true) {if (function_exists ("mb_substr") {$ slice = mb_substr ($ str, $ start, $ length, $ charset );} elseif (function_exists ('iconv _ substr') {$ slice = iconv_substr ($ str, $ start, $ length, $ charset );} else {$ re ['utf-8'] = "/[x01-x7f] | [xc2-xdf] [x80-xbf] | [xe0-xef] [x80-xbf] {2} | [xf0-xff] [x80-xbf] {3 }/"; $ re ['gb2312'] = "/[x01-x7f] | [ Xb0-xf7] [xa0-xfe]/"; $ re ['gbk'] ="/[x01-x7f] | [x81-xfe] [x40-xfe]/"; $ re ['big5'] = "/[x01-x7f] | [x81-xfe] ([x40-x7e] | xa1-xfe])/"; preg_match_all ($ re [$ charset], $ str, $ match); $ slice = join ("", array_slice ($ match [0], $ start, $ length);} $ fix = ''; if (strlen ($ slice) <strlen ($ str) {$ fix = '... ';} return $ suffix? $ Slice. $ fix: $ slice ;}
