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]
