The article introduces two methods to encrypt the PHP program itself. Our common method is base64_encode(gzdeflate($contents)) to encrypt. The second method is rare and friends in need can also refer to it.

Example 1

}
return false;
}
//Call function
$filename='dam.php';
encode_file_contents($filename);
echo "OK, encryption completed!"
?>

The code is as follows

代码如下

复制代码

function encode_file_contents($filename) {
$type=strtolower(substr(strrchr($filename,'.'),1));
if('php'==$type && is_file($filename) && is_writable($filename)){// 如果是PHP文件并且可写则进行压缩编码
$contents = file_get_contents($filename);// 判断文件是否已经被编码处理
$contents = php_strip_whitespace($filename);
// 去除PHP头部和尾部标识
$headerPos = strpos($contents,' $footerPos = strrpos($contents,'?>');
$contents = substr($contents,$headerPos+5,$footerPos-$headerPos);
$encode = base64_encode(gzdeflate($contents));// 开始编码
$encode = '";
return file_put_contents($filename,$encode);

}
return false;
}
//调用函数
$filename='dam.php';
encode_file_contents($filename);
echo "OK,加密完成！"
?>

Copy code

代码如下

复制代码

function encode_file_contents($filename) {
$type=strtolower(substr(strrchr($filename,'.'),1));
if('php'==$type && is_file($filename) && is_writable($filename)){// If it is a PHP file and can be written, compress it and encode it
$contents = file_get_contents($filename); // Determine whether the file has been encoded
$contents = php_strip_whitespace($filename);
// Remove PHP header and trailer tags
$headerPos = strpos($contents,' $footerPos = strrpos($contents,'?>');
$contents = substr($contents,$headerPos+5,$footerPos-$headerPos);
$encode = base64_encode(gzdeflate($contents));//Start encoding
$encode = '";
return file_put_contents($filename,$encode);
