复制代码 代码如下:

<?php if(strlen($r[title])>45){$str=utf8Substr($r[title],0,15).\"...\";}else{$str=$r[title];}echo $str; ?>
//截取utf8字符串
function utf8Substr($str, $from, $len)
{
return preg_replace(\'#^(?:[\\x00-\\x7F]|[\\xC0-\\xFF][\\x80-\\xBF]+){0,\'.$from.\'}\'.
\'((?:[\\x00-\\x7F]|[\\xC0-\\xFF][\\x80-\\xBF]+){0,\'.$len.\'}).*#s\',
\'$1\',$str);
}
