"Echo" My Age is: ". $this->age;    }}

 
  SUM ($a, $b);            return $this->prt ($a, $c);        }    }    $c =new cal ();    echo "(2+3) *10=". $c->result (' 2 ', ' 3 ', ' 10 ');? >

Can you explain it in detail? Not quite understand $this->prt () can be var mixed in parentheses?

Can you answer it in detail!

$this objects themselves

Like you.
$c =new cal (); Instantiate the Class Cal, when $c is the object
echo "(2+3) *10=". $c->result (' 2 ', ' 3 ', ' 10 '); You can access this object in this way $c

So how do you access the inside of the $c?
The answer is to use $this

$this->prt () should not be put inside.
You will get an error when executing to the $a* $c.
Unsupported operand types
It means that arrays and numbers cannot be multiplied.
The $this represents the instantiated object itself.
This object includes the PRT () method.
$this->prt () means that the execution of this object itself contains the PRT ()
General is the meaning of selection and execution.

Seems to be able to put, no error

Is it?
Can you execute this code? I have an error.
Can run the trouble to tell me the result.

 
  SUM ($a, $b);            return $this->prt ($a, $c);        }    }    $c =new cal ();    echo "(2+3) *10=". $c->result ($a, ' 3 ', ' 10 ');? >

This code does not work, but

 
  SUM ($a, $b);            return $this->prt ($a, $c);        }    }    $c =new cal ();    echo "(2+3) *10=". $c->result (' 2 ', ' 3 ', ' 10 ');? >

This code can run this section of my post

Of course it can run.

I don't know if I misunderstood the LZ's meaning.
