PHP reverses scenarios based on code and skillfully uses debug_ backtrace()

1. First write a method that counts the method call path

/** * @desc:  Statistics method call path  * @date: 2021-11-9 */
    public function statisticsAllFunctionPath()
    {
    
    	// Connect redis
        $redis = ZFactory::getRedis('***Redis');
        $redis_key = "FunctionPath";
        
        // Record scene path 
        $backtrace = debug_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS);
        $trace_path = "";
        foreach ($backtrace as $key => $trace){
    
            if($key == 0){
    
                $trace_path = $trace['function'];
            }else{
    
                $trace_path = $trace_path.'-'.$trace['function'];
            }
        }

        //md5 String path filtering  hash Eliminate duplicate data 
        $hash_key = md5($trace_path);
        if(!$redis->hExists($redis_key, $hash_key)){
    
            // non-existent   The insert hash value 
            $redis->hSet($redis_key, $hash_key, $trace_path);
        }

        if($_COOKIE['test'] == 2){
    
            echo "<pre>";
            var_dump($redis_key);echo "<br>";echo "<br>";    // Output ：FunctionPath 
            var_dump($hash_key);echo "<br>";echo "<br>";    // Output ：e2806d650d6a13384f412fce61196a1a
            var_dump($trace_path);echo "<br>";echo "<br>";    // Output ：sta********eplinkScene-c*******k-generateShareUrl-displayT6-display-call_user_func_array-call*****d-execute-renderComponent-dispatch
            exit();
        }
        return true;
    }

2. Where statistics are needed , Call the statistical method path method

public function createDeeplink()
    {
    
    	...
    	...
    	// Call the statistics method call the path method 
        $testModel = new TestModel();
        $testModel->statisticsAllFunctionPath();
		...
		...
	}		

3. Print redis Data collected , Push back the interface based on the collected data url

/* string(13) " All the data :" array(8) { ["e2806d650d6a13384f412fce61196a1a"]=>string(138) "sta********eplinkScene-c*******k-generateShareUrl-displayT6-display-call_user_func_array-call*****d-execute-renderComponent-dispatch" }  Based on the above data, the interface can be pushed back url：/index.php?com=test&t=display */

4. According to the interface pushed back url, Then go to find the location or scenario of the front-end calling interface
