想写一个查找1000条记录的 文本字段（1000个字符）,找出包含A字串,B字串,C字串的记录,对应替换沉D,E,F字符串,写回对应记录

第一天搞
$link = mysql_connect("*.*.*.*", "******", "******") or die("Could not connect
");
mysql_select_db("hdm0990625_db") or die("Could not select database
");

/* 执行 SQL 查询 */
$query = "SELECT goods_id,intro FROM sdb_goods where (intro like '%http://misc.360buyimg.com/product/skin/2013/i/20130604A.png%') or (intro like '%天猫%') or (intro like '%淘宝%') or (intro like '%%E5%A4%A9%E7%8C%A%') or (intro like '%%E6%B7%98%E5%AE%9D%') or (intro like '%%BA%AC%E4%B8%9C%')";
$result = mysql_query($query) or die("Query failed");


$i=0;
$txt="";
while($row = mysql_fetch_array($result))
{
//print $row['goods_id'];
$txt=str_replace("http://misc.360buyimg.com/product/skin/2013/i/20130604A.png","/themes/newjd/images/cndqc.png",$row['intro']);
$txt=str_replace("天猫","商城",$txt);
$txt=str_replace("淘宝","商城",$txt);
$txt=str_replace("京东","商城",$txt);
$txt=str_replace("%E5%A4%A9%E7%8C%A","商城",$txt);
$txt=str_replace("%E6%B7%98%E5%AE%9D","商城",$txt);
$txt=str_replace("%BA%AC%E4%B8%9C","商城",$txt);

mysql_query("UPDATE sdb_goods SET intro='".$txt."' WHERE goods_id = '".$row['goods_id']."'");

//print $txt;
//print "
";
$txt="";
$i++;
}

print "



";
print $i;

/* 释放资源 */
mysql_free_result($result);
/* 断开连接 */
mysql_close($link);
?>

程序有问题？
mysql_query("UPDATE sdb_goods SET intro='$txt' WHERE goods_id = '$row['goods_id']'");
mysql_query("UPDATE sdb_goods SET intro='".$txt."' WHERE goods_id = '".$row['goods_id']."'");

这２句哪句是对的？

回复讨论(解决方案)

$query = "SELECT goods_id,intro FROM sdb_goods where (intro like '%http://misc.360buyimg.com/product/skin/2013/i/20130604A.png%') or (intro like '%天猫%') or (intro like '%淘宝%') or (intro like '%%E5%A4%A9%E7%8C%A%') or (intro like '%%E6%B7%98%E5%AE%9D%') or (intro like '%%BA%AC%E4%B8%9C%')";


如果开头是

天猫　淘宝　查询不出来
