Why would a programmer need to use the function? How would the same results have been achieved in php 4?

In any scenario where you want to control how an object behaves when used in a string context (used as a string), e.g.
class FullName
{
protected $firstName;
protected $middleNames = array();
protected $lastName;
// ... methods ...
public function __toString()
{
return sprintf('%s %s %s', $this->firstName,
implode(' ', $this->middleNames),
$this->lastName);
}
}
$fullname = new FullName('John', array('Jim', 'Jamie'), 'Jackson');
echo "Hello, my name is $fullname";
You cannot simulate this method in PHP4. In fact, you shouldn't even be using PHP4 anymore at all.

Please see this question. If its available, its preferable to casting to achieve the same.
