<?php
$ory=mysql_connect("127.0.0.1:3306","root","");
$bgok0="select * from xia_zha order by thfc asc limit 0,4";
mysql_query("set names gb2312");
$bgok1=mysql_db_query("ok",$bgok0,$ory);
while($bgok2=mysql_fetch_array($bgok1)){
if($bgok2[biao_ti]>20){
echo substr($bgok2[biao_ti],0,20)."....<br>";
}else{
echo $bgok2[biao_ti];
}
}
?>我的意思是输出数据库里面的字符当大过20个字符的时候就在后面加....如果不大于20个字符就不用加....我的写法有些不对请帮我改一下谢谢
