Exception::getPrevious — Returns previous Exception
Returns previous Exception (the third parameter of Exception::__construct()).
Diese Funktion hat keine Parameter.
Returns the previous Exception if available or NULL otherwise.
Beispiel #1 Exception::getPrevious() example
Looping over, and printing out, exception trace.
<?php
class MyCustomException extends Exception {}
function doStuff() {
try {
throw new InvalidArgumentException("You are doing it wrong!", 112);
} catch(Exception $e) {
throw new MyCustomException("Something happend", 911, $e);
}
}
try {
doStuff();
} catch(Exception $e) {
do {
printf("%s:%d %s (%d) [%s]\n", $e->getFile(), $e->getLine(), $e->getMessage(), $e->getCode(), get_class($e));
} while($e = $e->getPrevious());
}
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
/home/bjori/ex.php:8 Something happend (911) [MyCustomException] /home/bjori/ex.php:6 You are doing it wrong! (112) [InvalidArgumentException]
