The StringBuilder class implementation method of PHP simulation asp.net _php skill

The StringBuilder class implementation method of PHP simulation asp.net is described in this paper. Share to everyone for your reference. as follows:

In the asp.net development environment, there is a StringBuilder class is more commonly used, this class can be used to achieve a very convenient text text operation. But in PHP, there is no such class. However, we can simulate this method by customizing the class.

/********************************************

    Array_push ($this->list, $str); 
  Public Function Append ($str) 
  { 
    Array_push ($this->list, $str); 
    return $this; 
  } 
  Public Function Appendline ($str) 
  { 
    Array_push ($this->list, $str. self::line); 
    return $this; 
  } 
  Public Function AppendFormat ($str, mixed $args) 
  { 
    Array_push ($this->list, sprintf ($str, $args)); 
    return $this;

  Public Function ToString () 
  {return 
    implode ("", $this->list); 
  } 
  Public Function __destruct ()
