唉,我都瞧不起我自己了, 亲们,存库时,我忘了转义
//PHP版本5.4以上:
json_encode($data,JSON_UNESCAPED_UNICODE);
//PHP版本5.2以上才有json_encode/json_decode系列函数。
//PHP版本5.2-5.3,可以利用PHP的urlencode/urldecode的组合使用,可以达到类似的保留中文的效果。
//示例如下:代码里的MyJsonEncode和MyJsonDecode函数可以保留中文。
<code>//数组转换保留为中文的JSON字符串 function MyJsonEncode($data){ return urldecode(json_encode(MyUrlEncode($data))); //需要PHP版本5.4以上: //return json_encode($data,JSON_UNESCAPED_UNICODE); } //保留中文的JSON字符串转换为数组 function MyJsonDecode($data){ $data = urlencode($data); $data = str_replace("%7B",'{',$data); $data = str_replace("%7D",'}',$data); $data = str_replace("%5B",'[',$data); $data = str_replace("%5D",']',$data); $data = str_replace("%3A",':',$data); $data = str_replace("%2C",',',$data); $data = str_replace("%22",'"',$data); return MyUrlDecode(json_decode($data,true)); } //自定义的URL编码 function MyUrlEncode($data) { //可对关联数组进行URL编码,并处理换行符 //内部递归调用 //用于MyJsonEncode函数调用 if(!is_array($data)){ $data = str_replace("\r",'\r',$data); $data = str_replace("\n",'\n',$data); $data = urlencode($data); } else { foreach($data as $key=>$value) { $data[MyUrlEncode($key)] = MyUrlEncode($value); if((string)MyUrlEncode($key)!==(string)$key){ unset($data[$key]); } } } return $data; } //自定义的URL解码 function MyUrlDecode($data) { //可对关联数组进行URL解码,并处理换行符 //内部递归调用 //用于MyJsonDecode函数调用 if(!is_array($data)){ $data = urldecode($data); $data = str_replace('\r',"\r",$data); $data = str_replace('\n',"\n",$data); } else { foreach($data as $key=>$value) { $data[MyUrlDecode($key)] = MyUrlDecode($value); if((string)MyUrlDecode($key)!==(string)$key){ unset($data[$key]); } } } return $data; } </code>

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
