PHP代码加密
记得我有个非常好的朋友曾经向我大倒苦水,原来他加了半个月的夜班,给别人开发了一套PHP程序,结果遇到了奸商,人家收了源代码说是先测试,然后就消失不见了,电话打不通,QQ也永远不在线了。
仔细想来,使用PHP开发的程序,都是源代码,辛辛苦苦写出来,任何人都可以拿去随便用随便改,这确实是个头疼的问题.
1,那么要怎么加密自己的php代码?
2,让加密的php代码在别人的电脑上也可以运行.
------解决思路----------------------
自己搞一个空间, 要测试的时候, 放自己的空间上。
------解决思路----------------------
加密的还是可以破解的,可以自己弄个站把代码上传到上面,别人可以通过域名查看效果,等他付费了再把源码给他
------解决思路----------------------
另存为的代码也只是页面html的,php的又看不到,不然程序员不悲催了

------解决思路----------------------
对 php 代码加密有专业的加密软件(收费的),加密后的代码要在相应的解密环境中运行
对 php 代码预编译有 zend 的预编译工具(收费,但有盗版的),预编译代码同样需要有 zend 的虚拟处理机
对 php 代码做扰码处理,扰码可理解为自解密的加密,运行时没有特殊要求
无论你做什么处理,客户总是要拿到能运行的代码的。至于客户用此代码做了什么不该做的事情,只有寻求法律的保护了
尽管中国人很聪明,但由于缺乏法律意识,在科技领域总是落后与美国人、日本人.....
------解决思路----------------------
放自己空间测试,测试好了再给。或是走担保交易啊。

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 = 'test.php';
encode_file_contents ( $filename );
echo "OK,加密完成!"?>

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.
