php使用header导出excel时会少第一行

http://192.168.0.200/test/khall.php?mindate=2014-04-01&maxdate=2014-04-30&keys=

='".$mindate."' and dates<='".$maxdate."'";        if (!empty($_GET['keys'])) {            $keys=$_GET['keys'];            $ww="(`area` like '%".$keys."%' or `type` like '%".$keys."%' or `names` like '%".$keys."%' or `add` like '%".$keys."%' or `dur` like '%".$keys."%')";            $wh="where {$ww} and {$dates}";  }           else{$wh="where {$dates}";}            $sql="SELECT * FROM `khxx` {$wh}";           // echo "$sql";            mysql_query('set names gbk');            $query=mysql_query($sql);            $rs=mysql_fetch_array($query);            while ($rs=mysql_fetch_array($query)){            echo "{$rs['dates']}\t{$rs['type']}\t{$rs['area']}\t{$rs['names']}\t{$rs['add']}\t{$rs['phone']}\t{$rs['no']}\t{$rs['set']}\t{$rs['dur']}\t{$rs['give']}\t{$rs['moneys']}\t{$rs['attn']}\t{$rs['username']}\t{$rs['rem']}\n";            }?>

SELECT * FROM `khxx` where dates>='2014-04-01' and dates<='2014-04-30'

回复讨论(解决方案)

还有就是使用了mysql_query('set names gbk');
但是上个页面会传递$key变量值 因为传递来的值是utf-8的 在执行sql语句时就会失效

$rs=mysql_fetch_array($query); //你这里多读了一行
while ($rs=mysql_fetch_array($query)){

$keys=$_GET['keys'];
改为
$keys = iconv('utf-8', 'gbk', $_GET['keys']);

%".$keys."% 改为%". iconv('utf-8', 'gbk', '$keys')."%

$keys=$_GET['keys'];
改为
$keys = iconv('utf-8', 'gbk', $_GET['keys']);
今天少了你的提点可怎么办呀

认识了规律就好了
