remote_addr PHP
网上很多伪造ip刷票,可是现在的网站获取ip只用$_SERVER["REMOTE_ADDR"],那应该如何去伪造呢?回复讨论(解决方案)
$_SERVER["REMOTE_ADDR"] 不可伪造!
但你可以通过代理来改变,当然他反映的是代理的IP,也是真实的
php的curl加代理就可以了。
首先你去找一堆代理ip,很容易就能找到上百个。
若是投票每个一小时才能投一次,那么你就可以每一小时投一百次,目前只能这样做了。
不过小心被封,我之前有帮同学弄过一次投票,后来那个展品被封了。。。

获取真实的ip 方法
function real_ip()
{
static $realip = NULL;
if ($realip !== NULL)
{
return $realip;
}
if (isset($_SERVER))
{
if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
{
$arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
/* 取X-Forwarded-For中第一个非unknown的有效IP字符串 */
foreach ($arr AS $ip)
{
$ip = trim($ip);
if ($ip != 'unknown')
{
$realip = $ip;
break;
}
}
}
elseif (isset($_SERVER['HTTP_CLIENT_IP']))
{
$realip = $_SERVER['HTTP_CLIENT_IP'];
}
else
{
if (isset($_SERVER['REMOTE_ADDR']))
{
$realip = $_SERVER['REMOTE_ADDR'];
}
else
{
$realip = '0.0.0.0';
}
}
}
else
{
if (getenv('HTTP_X_FORWARDED_FOR'))
{
$realip = getenv('HTTP_X_FORWARDED_FOR');
}
elseif (getenv('HTTP_CLIENT_IP'))
{
$realip = getenv('HTTP_CLIENT_IP');
}
else
{
$realip = getenv('REMOTE_ADDR');
}
}
preg_match("/[\d\.]{7,15}/", $realip, $onlineip);
$realip = !empty($onlineip[0]) ? $onlineip[0] : '0.0.0.0';
return $realip;
}

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
