對於thinkphp的截取字串函數無法顯示省略符號的情況，可以參考如下解決方案：開啟common/extend.php頁面，修改msubstr函數為：
- function msubstr($str, $start=0, $length, $charset="utf-8", $suffix=true)
- {
- if(function_exists("mb_substr")) {
- if($suffix)
- {
- if($str==mb_substr($str, $start, $length, $charset))
- {
- return mb_substr($str, $start, $length, $charset);
- }
- else
- {
- return mb_substr($str, $start, $length, $charset)."...";
- }
- } // bbs.it-home.org
- else
- {
- return mb_substr($str, $start, $length, $charset);
- }
- }
- elseif(function_exists('iconv_substr')) {
- if($suffix)
- {
- if($str==iconv_substr($str,$start,$length,$charset))
- {
- return iconv_substr($str,$start,$length,$charset);
- }
- else
- {
- return iconv_substr($str,$start,$length,$charset)."...";
- }
- }
- else
- {
- return iconv_substr($str,$start,$length,$charset);
- }
- }
- $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, $length));
- if($suffix) return $slice."…";
- return $slice;
- }
複製代碼使用以上函數在截取字串時，就可以顯示省略符號了，大家可以測試下看看效果如何。 |
