After receiving the Log recording task, Shuai was relieved to study it...

In fact, according to the boss's level, he is familiar with the open-source framework, and it is easy to write a common Logger. Why does he want to do it?

At that time, he couldn't figure it out because he had never experienced that stage.

Shuai's idea is actually quite simple, that is, to complete the tasks assigned by the boss and become a good employee capable of the job.

Shuai is not sensitive to demands at this stage, so he will study technical details as soon as he receives the task. I don't know if the code has been written.

The first draft of Shuai is to try to use the object-oriented thinking ability to write this Log record task. The first draft is as follows:

class Logger {        public static function log($message){        $file = fopen('application.error.log', "a+");        fwrite($file, $message);        fclose($file);    }}

The code for TopClient is as follows:

class TopClient {    ......    protected function logCommunicationError($apiName, $requestUrl, $errorCode, $responseTxt)    {        $localIp = isset($_SERVER["SERVER_ADDR"]) ? $_SERVER["SERVER_ADDR"] : "CLI";        $logData = "API_NAME:$apiName,APP_KEY:$this->appkey,CLIENT_IP:$localIp,SDK_VERSION:$this->sdkVersion,REQUEST_URL:$requestUrl,ERROR_CODE:$errorCode,ERROR_MSG:".str_replace("\n","",$responseTxt);        Logger::log($logData);    }    ......}

In fact, this is an improvement, and Shuai is finally slowly changing his thinking ability.

When Shuai found the boss with this code, he was very worried about it, but not what he wanted, so he said to him:

1. if you want to record the error log, how do you expect it to be used and what information you want to see.

2. if you want to record the warning log, how do you expect it to be used and what information you want to see.

3. if you want to debug the code and want to see the code execution efficiency, how do you expect it to be used and what information you want to see.

Why did the three handsome guys overwhelm me? I was a little angry when I heard it.

In this way, handsome boy thinks about what the boss says.

When Shuai was lucky enough to understand the meaning, he learned more powerful ways of mind. we hope he will be able to get started.

In Baidu search engines, search words match promotion keywords, for example?

Currently, Baidu has three matching methods: precision, phrase, and broad. Generally, the golden match method is: wide match + search term Report + negative keyword. In terms of traffic, it is widely used> phrase> accurate. you can set it based on your actual situation!
