Exception::getMessage
May be I am late (5.2 is not supported). But if you want use the functionality of "previous Exception" in PHP < 5.3 or write compatible code, you can use next way as below.
<?php
abstract class App_Exception_PreviousNativeAbstract extends Exception {
public static $printPrevious = true;
public function __toString() {
$result = array();
$result[] = sprintf("Exception '%s' with message '(%s) %s' in %s:%d", get_class($this), $this->code, $this->message, $this->file, $this->line);
$result[] = '---[Stack trace]:';
$result[] = $this->getTraceAsString();
if (self::$printPrevious) {
$previous = $this->getPrevious();
if ($previous) {
do {
$result[] = '---[Previous exception]:';
$result[] = sprintf("Exception '%s' with message '(%s) %s' in %s:%d", get_class($previous), $previous->getCode(), $previous->getMessage(), $previous->getFile(), $previous->getLine());
$result[] = '---[Stack trace]:';
$result[] = $previous->getTraceAsString();
} while(method_exists($previous, 'getPrevious') && ($previous = $previous->getPrevious()));
}
}
return implode("\r\n", $result);
}
}
abstract class App_Exception_PreviousLegacyAbstract extends App_Exception_PreviousNativeAbstract {
protected $previous;
public function __construct($message, $code = 0, Exception $previous = null) {
$this->previous = $previous;
parent::__construct($message, $code);
}
public function getPrevious() {
return $this->previous;
}
}
if (version_compare(PHP_VERSION, '5.3.0', '>=')) {
abstract class App_Exception_PreviousAbstract extends App_Exception_PreviousNativeAbstract {}
}
else {
abstract class App_Exception_PreviousAbstract extends App_Exception_PreviousLegacyAbstract {}
}
class App_Exception extends App_Exception_PreviousAbstract {
public function __construct($message, $code = 0, Exception $previous = null) {
parent::__construct($message, 0, $previous);
}
}
// Example:
try {
// ...
throw new Exception('Exception mesage');
// ...
} catch (Exception $e) {
throw new App_Exception('App exception mesage', 0, $e);
}
?>

Ejemplos
Ejemplo #1 Ejemplo de Exception::getPrevious()
Recorre e imprime las excepciones.
<?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());
}
?>
El resultado del ejemplo sería algo similar a:
/home/bjori/ex.php:8 Something happend (911) [MyCustomException] /home/bjori/ex.php:6 You are doing it wrong! (112) [InvalidArgumentException]
