ThinkPHP 模板substr的截取字符串函数
在Common/function.php加上以下代码/**<br>
** 截取中文字符串<br>
**/<br>
function msubstr($str, $start=0, $length, $charset="utf-8", $suffix=true){<br>
if(function_exists("mb_substr")){<br>
$slice= mb_substr($str, $start, $length, $charset);<br>
}elseif(function_exists('iconv_substr')) {<br>
$slice= iconv_substr($str,$start,$length,$charset);<br>
}else{<br>
$re['utf-8'] = "/[x01-x7f]|[xc2-xdf][x80-xbf]|[xe0-xef][x80-xbf]{2}|[xf0-xff][x80-xbf]{3}/";<br>
$re['gb2312'] = "/[x01-x7f]|[xb0-xf7][xa0-xfe]/";<br>
$re['gbk'] = "/[x01-x7f]|[x81-xfe][x40-xfe]/";<br>
$re['big5'] = "/[x01-x7f]|[x81-xfe]([x40-x7e]|xa1-xfe])/";<br>
preg_match_all($re[$charset], $str, $match);<br>
$slice = join("",array_slice($match[0], $start, $length));<br>
} <br>
$fix='';<br>
if(strlen($slice)
$fix='...';<br>
}<br>
return $suffix ? $slice.$fix : $slice;<br>
}前端页面需要截取字符串时{$v.title|msubstr=0,5}
