在这份教程中,我们将会学习到如何阻止用户通过PHP上传成人照片或者裸照.
我在phpclasses.org上面偶然发现一个很有用的,由Bakr Alsharif开发的可以帮助开发者基于皮肤像素点来检测图片裸照的类文件.
它会分析在一张图片的不同部分使用的颜色,并决定其是否匹配人类皮肤颜色的色调.
作为分析的结果,他会返回一个反映图片包含裸露的可能性的分值.
此外,他还可以输出被分析的图片,上面对使用给定颜色的肤色的像素进行了标记.
当前它可以对PNG,GIF和JPEG图片进行分析.
PHP
下面展示了如何使用这个PHP类.
让我们先从包含裸体过滤器,nf.php文件开始.
代码如下:
include ('nf.php');
接下来,创建一个新的名叫ImageFilter的类,然后把它放到一个叫做$filter的变量中.
代码如下:
$filter = new ImageFilter;
获取图片的分值并将其放到一个$score变量中.
代码如下:
$score = $filter -> GetScore($_FILES['img']['tmp_name']);
如果图片分值大于或等于60%,那就展示一条(告警)消息.
代码如下:
if($score >= 60){
/*Message*/
}
下面是所有的PHP代码:
代码如下:
/*Include the Nudity Filter file*/
include ('nf.php');
/*Create a new class called $filter*/
$filter = new ImageFilter;
/*Get the score of the image*/
$score = $filter -> GetScore($_FILES['img']['tmp_name']);
/*If the $score variable is set*/
if (isset($score)) {
/*If the image contains nudity, display image score and message. Score value if more than 60%, it is considered an adult image.*/
if ($score >= 60) {
echo "Image scored " . $score . "%, It seems that you have uploaded a nude picture.";
/*If the image doesn't contain nudity*/
} else if ($score
echo "Congratulations, you have uploaded an non-nude image.";
}
}
?>
标记语言
我们可以使用一个基础的HTML表单上传图片.
代码如下:
总结
请记得,PHP不能够检测所有的裸体图片,所以不完全可信.我希望你觉得这还有点用处.

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.
