android客户端和php+mysql+apache搭建之间的简单交互,实现log信息存储。
实现原理就是android客户端发送请求,传给服务器log信息,服务器收到这些,连接数据库进行存储,并将存储后的状态返回给客户端。
服务器端:
先在mysql里面建一个testlog的数据库,里面有一个log_info表,记录了LogCategory,System,Executor,Action等信息。
在php的虚拟目录下新建一个php项目testlog,创建conn.php和log_deal.php文件。
<?php include_once('conn.php'); //echo '$_POST接收:</br>'; $System = $_POST['System']; $LogCategory = $_POST['LogCategory']; $Executor = $_POST['Executor']; $Action = $_POST['Action']; $sqlstr = "insert into log_info(System,LogCategory,Executor,Action,CreateTime) values('".$System."','".$LogCategory."','".$Executor."','".$Action."','".date('Y-m-d H:m:s')."')"; if (mysql_query($sqlstr)){ echo "succeed"; } else { die(mysql_error()); echo "error"; }?>服务器搭建完成。
android客户端:
布局随意写一下就OK了
下面是主要代码:
class SendlogHandler implements Runnable{ @Override public void run() { try { String url = "http://localhost/testlog/log_deal.php"; String result = null; boolean isSendSucceed = false; HttpPost httpRequest = new HttpPost(url); List params = new ArrayList(); params.add(new BasicNameValuePair("System", "系统名称")); params.add(new BasicNameValuePair("LogCategory", "LOG等级")); params.add(new BasicNameValuePair("Executor", "操作人")); params.add(new BasicNameValuePair("Action", "发生了什么事")); httpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8)); HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest); int stateCode = httpResponse.getStatusLine().getStatusCode(); if (stateCode == 200){ HttpEntity httpEntity = httpResponse.getEntity(); result = EntityUtils.toString(httpEntity); } if (result.equals("succeed")){ isSendSucceed = true; } Message msg = new Message(); msg.what = 2; msg.obj = isSendSucceed; handler.sendMessage(msg); } catch (Exception e){ e.printStackTrace(); } } }好了,简单的客户端post数据到php服务器端存储的功能已经完成了。

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.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
