Question

I am working on a PHP project that involves making a email class. I have a Java background, and cannot seem to figure out the syntax for calling methods on objects.

I’ll abbreviate the code:

FILE 1:

class Emails {

protected $to;

public function Emails ($_to) {
 //constructor function. 
  $to = $_to;
}

public function getTo () {
  return $to;
}

FILE 2:

require("../phpFunctions/EmailClass.php");//include the class file
$email = new Emails("<email here>");
echo $email->getTo();//get email and return it

However, getTo() keeps returning either nothing, or, if I change the return to $this->$to, I receive an “empty field” error.

Please help me understand how methods work in this instance (and forgive the pun…). In Java, you would just call email.getTo()…

Answer 1

public function __construct ($_to) {
  $this->to = $_to;
}    
public function getTo () {
  return $this->to;
}
