Hi Peter,
As you probably already know, PHP 4 constructors are functions named
after the class
<?php
class Foo
{
function Foo()
{
echo "in constructor";
}
}
$a = new Foo;
?>
Although destructor emulation is implemented in the PEAR class
(destructor would be function _Foo), I don't recommend using a
destructor in PHP 4. Instead, manually destruct your objects. PEAR
does it with a shutdown function, so if performance is not a question,
by all means, use PEAR's implementation. It has been battle-tested for
years and years.
However, I wouldn't bother with writing new code in PHP 4. It will be
cheaper for you to switch hosting providers to one that allows you to
use PHP 5. Why? You will waste tons of time working around reference
issues that are non-existent in PHP 5 due to object handles.
