Question

    public static function assign($name, $value)
    {
        $this->params[] = array($name => $value);
    }

    public static function draw()
    {
        return $this->params;
    }
}


<?php
    $test = Templater::assign('key', 'value')->draw();
    print_r($test);

I need to function “assign” was static, but $params was common for the whole class..
But this code is not working.

Fatal error: Using $this when not in object context

Any ideas?

Answer 1

Singleton would work nice here

class Templater {
  private static $instance = null;
  private $params = array();

  public function __construct(){
    return $this;
  }

  public static function instance(){
    if(is_null(self::$instance)) self::$instance = new self();
    return self::$instance;
  }

  public function assign($name, $value){
    $this->params[$name] = $value;
    return $this;
  }

  public function draw(){
    return $this->params;
  }
}

Usage:

$test = Templater::instance()
  ->assign('var1', 'value1')
  ->assign('var2', 'value2')
  ->draw();
print_r($test);
