php判断上传文件大小的示例代码

代码如下：

120 || $arr[2]>60){

echo "";
exit();
    }
       
    switch ($type) {
case 'image/pjpeg' :
    $ok = 1;
    break;
case 'image/jpeg' :
    $ok = 1;
    break;
case 'image/gif' :
    $ok = 1;
    break;
    //case 'image/x-png' :
    //    $ok = 1; //IE为x-png；FOX为png
    //    break;
    }
    if ($ok && $error == '0') {
       move_uploaded_file($tmp_name, "c:/" . $name);
       return $name;
    }
} else {
    return null;
}
}
?>
