APPSERV权限问题???

刚开始研究php，碰到了个问题，代码如下：
<?php
include('db_login.php');
// require_once('../php5/PEAR/DB.php');
$connection=mysql_connect($db_host,$db_username,$db_password);
$db_select=mysql_select_db($db_database);
if(!connection or !$db_select)
{
die("Could non connect mysql:<br/>".mysql_error());
}
$query="DROP TABLE books";

$result=mysql_query($query);
if(!$result)
{
die("Could not query the database:<br>".mysql_error());
}
else{
echo "Drop successfully!";
}
mysql_close($connection);
?>
这段代码出现了这个错误
Could not query the database:
Error on delete of '.\jttest\books.MYI' (Errcode: 13)

还有一段代码：

<?php
$maxsize=28480;//最大上传限制
if(!$HTTP_POST_VARS['submit'])
{
//print_r($HTTP_POST_FILES);
$error=" ";
// 导致跳过其余处理上传表单
}

if(!is_uploaded_file($HTTP_POST_FILES['upload_file']['tmp_name']) and !isset($error))
{
$error="<b>You must upload a file</b><br><br>";
unlink($HTTP_POST_FILES['upload_file']['tmp_name']);

}
if($HTTP_POST_FILES['upload_file']['size']>$maxsize and !isset($error))
{
$error="<b>Error,file must be lass than $maxsize bytes</b><br><br>";
unlink($HTTP_POST_FILES['upload_file']['size']);
}
if ($HTTP_POST_FILES['upload']['type']!="image/gif" and
$HTTP_POST_FILES['upload']['type']!="image/pjpeg" and
$HTTP_POST_FILES['upload']['type']!="image/jpeg" and !isset($error)){
$error="<b>You may only upload .gif or .jpg files</b><br><br>";
unlink($HTTP_POST_FILES['upload_file']['tmp_name']);
}
if(isset($error))
{
copy($HTTP_POST_FILES['upload_file']['tmp_name'],"uploads".$HTTP_POST_FILES['upload_file']['name']);
unlink($HTTP_POST_FILES['upload_file']['tmp_name']);
echo "Thank you for your upload.";
exit;
}
else {echo($error);}
?>
<html>
<head><title>Upload Files Test</title>
</head>
<body>
<form action="<?php $PHP_SELF?>" method="post" enctype="multipart/form-data">
Choose a file to upload:<br>
<input type="file" name="upload_file" size="80">
<br>
<input type="submit" name="sumbit" value="UPLOAD">
</form>
</body>
</html>这个出现错误是:  Warning: unlink() [function.unlink]: Permission denied   都是权限问题，怎么回事呢？想不通啊，难道是我直接作用于我自己的www文件夹？
