Cleanest way to execute code outside of try block only if no exception is thrown

Question

This question is about the best way to execute code outside of try block only if no exception is thrown.

try {
    //experiment
    //can't put code after experiment because I don't want a possible exception from this code to be caught by the following catch. It needs to bubble.
} catch(Exception $explosion) {
    //contain the blast
} finally {
    //cleanup
    //this is not the answer since it executes even if an exception occured
    //finally will be available in php 5.5
} else {
    //code to be executed only if no exception was thrown
    //but no try ... else block exists in php
}

This is method suggested by @webbiedave in response to the question php try .. else. I find it unsatisfactory because of the use of the extra $caught variable.

$caught = false;

try {
    // something
} catch (Exception $e) {
    $caught = true;
}

if (!$caught) {

}

So what is a better (or the best) way to accomplish this without the need for an extra variable?

Answer 1

One possibility is to put the try block in a method, and return false if an exception is cought.

function myFunction() {
    try {
        // Code  that throws an exception
    } catch(Exception $e) {
        return false;
    }
    return true;
}
