Thinkphp模板如何进行中文字符串截取?

Question

{$vons.title|msubstr=0,26} 像这样，总是显示错误，说msubstr函数未定义，在使用这个函数之前是否需要引入什么文件？

Answer 1

Common/common.php中定义函数：function msubstr($str, $start=0, $length, $charset="utf-8", $suffix=true){if(function_exists("mb_substr")){if ($suffix && strlen($str)>$length)return mb_substr($str, $start, $length, $charset)."...";elsereturn mb_substr($str, $start, $length, $charset);}elseif(function_exists('iconv_substr')) {if ($suffix && strlen($str)>$length)return iconv_substr($str,$start,$length,$charset)."...";elsereturn 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;}
