Class Details

[line 92]
Base PEAR_Exception Class

Features:

Nestable exceptions (throw new PEAR_Exception($msg, $prev_exception))
Definable triggers, shot when exceptions occur
Pretty and informative error messages
Added more context info avaible (like class, method or cause)

Ideas:

Maybe a way to define a 'template' for the output

1) Inherited properties from PHP Exception Class:

protected $message protected $code protected $line protected $file private $trace

2) Inherited methods from PHP Exception Class:

__clone __construct getMessage getCode getFile getLine getTrace getTraceAsString __toString

3) Usage example

  require_once 'PEAR/Exception.php';

 
  class Test {
     function foo() {
         throw new PEAR_Exception('Error Message', ERROR_CODE);
     }
  }
 
  function myLogger($pear_exception) {
     echo $pear_exception->getMessage();
  }
  // each time a exception is thrown the 'myLogger' will be called
  // (its use is completely optional)
  PEAR_Exception::addObserver('mylogger', 'myLogger');
  $test = new Test;
  try {
     $test->foo();
  } catch (PEAR_Exception $e) {
     print $e;
  }
