Difference between Php 4 and php5


Difference in object assignment: 



  
Example:

class Person {
  var $name;
  function getName()
  {
    return $this->name;
   }
  function setName($name)
  {
    $this->name = $name;
  }
  function Person($name)
  {
    $this->setName($name);
   }
}
function changeName($person, $name)
{
   $person->setName($name);
}
$person = new Person("Andi");
changeName($person, "Stig");
echo "Name is :". $person->getName();

Result:
Php 4 :Name is Andi
Php 5 :NAme is Stig

Note: the ones who were aware of this problem , should have a sleepless nights trying to
track down weird bugs that they could not pinpoint.

Hope this blog will help most of the php4 developers
