php上传问题

mac底下上传有点怪：<body>
    <?php
        $fileName=$_FILES["myFile"]["name"];
        move_uploaded_file($_FILES["myFile"]["tmp_name"],"/Application/XAMPP/".$fileName);
        echo $_FILES["myFile"]["tmp_name"];
    ?>
<form action="2.php" enctype="multipart/form-data" method="post">
    <input type="file" name="myFile" id="">
    <input type="submit" value="上传">
</form>
</body>echo $_FILES["myFile"]["tmp_name"]的结果是：
/Applications/XAMPP/xamppfiles/temp/phpnxKgdV所以我在move_uploaded_file（）给的第2个参数是"/Application/XAMPP/".$fileName报错：
Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/Applications/XAMPP/xamppfiles/temp/phpVWQDKw' to '/Application/XAMPP/flux.js' in /Applications/XAMPP/xamppfiles/htdocs/jquery/2.php on line 10
