The PHP magic __call method accepts two arguments.

• $method

• $parameters

• __call($method, $parameters)

• The $method variable

  • Is a string

  • Is the name of the actual method that was called.
    
    

• The $parameters variable 

  • Is an array

  • The array is filled with the parameters passed to the method that was called.

Another way to think about $method is like this: 

$building->$method($parameters)

•  $building->height($parameters)

  • • • $method = "height"

• $building->floors($parameters)

  • • • $method = "floors"

• $building->windows($parameters)

  • • • $method = "windows"

Another way to think about $parameters is like this: 

$building->$method($parameters)

•  $building->$method("one", "two", "three")

  • • • $parameters = ["one", "two", "three"]

• $building->$method(1)

  • • • $parameters = [1]

• $building->$method()

  • • • $parameters = []

Together you can think about the magic __call method like this.

•  $building->height("one", "two", "three")

  • • • • $method = "height"

        • $parameters = ["one", "two", "three"]

•  $building->floors(1)

  • • • $method = "floors"

      • $parameters = [1]

• $building->windows()

  • • • $method = "windows"

• • • • • • $parameters = []
