Question

i used to have a function defined like this (that is working fine under ubuntu 9.10):

public function __toString( $surNameFirst = false) { 
     if ($this->givenName . $this->surname == '') return null;
     else .......
}

after i have updated my machine to ubuntu 10.04( and php version Version: 5.3.2-1ubuntu4.2
) my app starts to show an error like this one ==>

Fatal error: Method Application_Model_Person::__tostring() cannot take arguments in /home/speshu/Development/where/application/models/Person.php on line 39

Answer 1

As of version 5.3 The __toString magic method can no longer accept arguments.

In any case should you really be doing that with a magic method? Why not declare toString($whatever) instead?
