//function //laravel 官方打印sql
    public static function printAllSql(){
        DB::listen(function($query) {
            $sql_arr = [];
            $bindings = $query->bindings;
            $sql = $query->sql;
            foreach ($bindings as $replace){
                $value = is_numeric($replace) ? $replace : "‘".$replace."‘";
                $sql = preg_replace(‘/\?/‘, $value, $sql, 1);
            }
            $sql_arr[] = $sql;
            print_r($sql_arr);
        });
    }

printAllSql();
