Bug description:  __toString() problem with an integer return

Description:
------------
When we want to use __toString() method for an object we can't return a
integer, that's a problem for example if we have a class named Zip and
__toString() method have to return zipcode.

I my example, seconde class represent the fix in php : we have to force
implicit conversion from integer to string

Reproduce code:
---------------
<?php 
Class Zip
{
  protected $zipcode = 33000;

  public function __toString() 
  {
    return $this->zipcode;
  }
}

$zip = new Zip();
echo  'Zip : ' .$zip;
?>

// and now the fix
Class Zip2
{
  protected $zipcode = 33000;
  
  public function __toString()
  {
    return (string) $this->zipcode;
  }
}
 


Expected result:
----------------
Zip : 33000

Actual result:
--------------
Catchable fatal error: Method Zip::__toString() must return a string value
