微信开发中有个问题,$this->logger("R ".$postStr);
<code>public function responseMsg() { $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];//保留xml类型原始数据 if (!empty($postStr)){ $this->logger("R ".$postStr); $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);//把数据载入到对象postObj中 $RX_TYPE = trim($postObj->MsgType);//调用对象postObj里的MsgType switch ($RX_TYPE) { case "event": $result = $this->receiveEvent($postObj); break; case "text": $result = $this->receiveText($postObj); break; } $this->logger("T ".$result); echo $result; } }</code>
<code>private function logger($log_content) { }</code>
代码如上,问题是
$this->logger("R ".$postStr);
$this->logger("T ".$result);
这两行代码的作用是?
<code>//写日志,参数log_content传日志的内容 private function logger($log_content){ //日志大小 1000KB echo "6"; $max_size = 1000; $log_filename = "log.xml"; if(file_exists($log_filename) && (abs(filesize($log_filename)) > $max_size)){ unlink($log_filename); } file_put_contents($log_filename,date("H:i:s")." ".$log_content."\n",FILE_APPEND); }</code>
百度看到了这个...这个看懂了点,但是我之前那个logger方法是空的也有用吗?

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

In PHP, you can effectively prevent CSRF attacks by using unpredictable tokens. Specific methods include: 1. Generate and embed CSRF tokens in the form; 2. Verify the validity of the token when processing the request.

H5. The main difference between mini programs and APP is: technical architecture: H5 is based on web technology, and mini programs and APP are independent applications. Experience and functions: H5 is light and easy to use, with limited functions; mini programs are lightweight and have good interactiveness; APPs are powerful and have smooth experience. Compatibility: H5 is cross-platform compatible, applets and APPs are restricted by the platform. Development cost: H5 has low development cost, medium mini programs, and highest APP. Applicable scenarios: H5 is suitable for information display, applets are suitable for lightweight applications, and APPs are suitable for complex functions.

Strict types in PHP are enabled by adding declare(strict_types=1); at the top of the file. 1) It forces type checking of function parameters and return values to prevent implicit type conversion. 2) Using strict types can improve the reliability and predictability of the code, reduce bugs, and improve maintainability and readability.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

In PHP, the final keyword is used to prevent classes from being inherited and methods being overwritten. 1) When marking the class as final, the class cannot be inherited. 2) When marking the method as final, the method cannot be rewritten by the subclass. Using final keywords ensures the stability and security of your code.

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.
