How can I get around the lack of a finally block in PHP?

Question

PHP prior to version 5.5 has no finally block - i.e., whereas in most sensible languages, you can do:

try {
   //do something
} catch(Exception ex) {
   //ha

Here is my solution to the lack of finally block. It not only provides a work around for the finally block, it also extends the try/catch to catch PHP errors (and fatal errors too). My solution looks like this (PHP 5.3):

_try(
    //some piece of code that will be our try block
    function() {
        //this code is expected to throw exception or produce php error
    },

    //some (optional) piece of code that will be our catch block
    function($exception) {
        //the exception will be caught here
        //php errors too will come here as ErrorException
    },

    //some (optional) piece of code that will be our finally block
    function() {
        //this code will execute after the catch block and even after fatal errors
    }
);
