"<br />"; } public function setPhone($p) { $this->$phone = $p; } public function getPhone() { return $this->$phone . "<br />"; } public function setMail($m) { $this->$mail = $m; } public function getMail() { return $this->$mail . "<br />"; } } $a = new Customer; echo $a->getName(); echo $a->getPhone(); echo $a->getMail(); $a->setName("A"); $a->setPhone("2818"); $a->setMail("gmail.com"); echo $a->getName(); echo $a->getPhone(); echo $a->getMail(); ?> for some reason i get error for the phone and mail variables: Notice: Undefined variable: phone in /home/stud/2011/3/avile/public_html/ex1a/index.php on line 26 Fatal error: Cannot access empty property in /home/stud/2011/3/avile/public_html/ex1a/index.php on line 26 But i dont get this error for the name variable.
