Example #1 Error::getPrevious() example

Looping over, and printing out, error trace.

<?php
class MyCustomError extends Error {}

function doStuff() {
    try {
        throw new InvalidArgumentError("You are doing it wrong!", 112);
    } catch(Error $e) {
        throw new MyCustomError("Something happened", 911, $e);
    }
}


try {
    doStuff();
} catch(Error $e) {
    do {
        printf("%s:%d %s (%d) [%s]\n", $e->getFile(), $e->getLine(), $e->getMessage(), $e->getCode(), get_class($e));
    } while($e = $e->getPrevious());
}
?>

The above example will output something similar to:

/home/bjori/ex.php:8 Something happened (911) [MyCustomError]
/home/bjori/ex.php:6 You are doing it wrong! (112) [InvalidArgumentError]
