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.
include ('nf.php');
$filter = new ImageFilter;
$score = $filter -> GetScore($_FILES['img']['tmp_name']);
if($score >= 60){
/*Message*/
}
/*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.";
}
}
?>
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.
复制代码 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.
复制代码 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.
复制代码 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.
复制代码 代码如下:
if($score >= 60){
/*Message*/
}
下面是所有的PHP代码:
复制代码 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.
复制代码 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.
